If you love your Polaris side by side, then you know how important it is to choose the best RZR battery for your machine. The wrong size or type of battery can leave you stranded in the middle of nowhere and can even cause damage to your engine. To make sure that you get the best performance and longevity from your RZR, it’s important to select the most suitable battery for your needs. Here are some tips on selecting the best RZR battery for your ride.

The first thing to consider when selecting a battery is the amount of power you need. How much power do you need from a single charge? The amount of power required will depend on several factors, including where and how often you use your RZR and what type of accessories or upgrades you have installed on it. Knowing what type of accessories or upgrades can help determine which type and size of battery will best meet those needs.

The second factor to consider is whether AGM (Absorbent Glass Mat) or GEL (Gel Cell) batteries are more suitable for powering your Polaris RZR. AGM batteries are spill-proof and generally last longer than GEL batteries, but they also require more recharging time between uses. GEL batteries tend to produce more consistent power over time but are not spill-proof like AGM batteries so they may require additional protection when storing or transporting them in rough terrain.

Finally, make sure to check out the warranties provided by different companies before purchasing a new battery for your Polaris RZR as some companies may offer different levels of coverage depending on how long it is meant to last or where it will be used as well as additional features that come with certain types of batteries that may offer better performance and durability over time.

Types of Batteries

When it comes to the best battery for RZR 800 side by sides, there are various types to choose from. Each type has its own advantages and disadvantages that you should consider when selecting the best one for your model.

Let’s take a look at the different types of batteries and what they offer.

Lead Acid Batteries

Lead acid batteries are a popular choice for automotive and industrial applications. They are reliable, offer good performance and are fairly inexpensive compared to other types of batteries. Lead acid battery design and construction varies greatly, depending on the type of application it is intended for.

One of the most common applications for lead acid batteries is in vehicles, such as cars and off-road vehicles. These types of lead acid batteries are designed to provide high power output over a relatively long period of time, while also being able to recharge quickly when completely drained. Lead acid batteries can also be found in boats, motorcycles and some aircrafts, as well as other everyday appliances.

Within this category, there are several different types: wet cell (flooded), absorbed glass mat (AGM), gel cell, valve-regulated (or sealed) lead-acid (VRLA), dual purpose (deep cycle / starting), starting only. Each type features its own benefits, so it’s important to understand what kind of battery you require before making a purchase.

Wet Cell: Traditional flooded lead-acid battery that is the most economical type; this type needs maintenance but offers robust performance over the longest life span.

Absorbed Glass Mat: Absorbed glass mat or AGM technology provides superior heat an corrosion resistance with very low internal resistance; allows safer operation when mounted on its side or tilted position as compared to wet cells with spillage risks and gassing problems at higher rates of charge/discharge cycles.

Gel Cell: This type features a “gel” electrolyte suspended inside the casing; designed for superior cycling capability (higher rate of charge/discharge cycles), maximum vibration resistance due to encasement and relatively maintenance free operating conditions under normal circumstances; generally more expensive than other types due to gel technology costs associated with manufacture process.

Valve Regulated Lead Acid: These sealed batteries do not require topping up with distilled water or electrolyte like wet cells do; instead they feature an integrated valve at the top that works both ways releasing internal gases when needed during charging or recharging and trapping them afterwards as long as voltage levels remain above designated thresholds; they can be mounted in any orientation which is an advantage over AGMs but cost slightly more due to intricate design requirements associated with built-in valve mechanism

Dual Purpose: Designed both for starting purposes such as car engines where high cranking amp surges over shorter periods followed by slower gradual discharges required if vehicle isn’t used again until next start up period arrives; also capable of deeper discharges than simply shallow usage used in starting instances without damaging itself if recharged shortly afterwards thus making it suitable for deep cycle applications under appropriate technical settings modified from factory settings per manufacturer guidelines if necessary

Starting Only: similar design principles applicable towards single use purpose only applicable towards start ups where quick surges required followed by slow discharge levels whilst vehicle chained idle before next start up utilising same battery unit again

Lithium Batteries

Lithium batteries are a popular choice for many different power equipment and devices, including recreational vehicles (RV), motorcycles, snowmobiles, all-terrain vehicles (ATV) and utility task vehicles (UTV). This type of battery offers several advantages when compared to traditional lead-acid batteries.

For starters, lithium batteries are significantly lighter than their lead-acid counterparts. This means that these batteries can provide more power in a smaller package. In addition, they tend to have higher energy density, meaning they can store more energy in a given size or weight than other types of battery technology.

Another advantage is that lithium batteries have longer life cycles. As long as they are properly taken care of, they put out consistent performance over long periods of time with minimal maintenance required. Finally, because they are so light and efficient with energy storage and delivery, they tend to be less expensive to buy and use than other types of non-rechargeable batteries or alternative forms of power such as fuel cells or solar cells.

Lithium batteries also come in different sizes and configurations for RVs and other units that require larger quantities of power generation such as uninterruptible power supplies (UPS) or large UPS systems designed around lithium ion technology. There is now even the possibility for owners to select from various more specialized types such as “deep cycle” Lithium Iron Phosphate (LiFePO4) batteries which are most commonly used in electric bicycles or RV conversions due their high discharge capacity rate and ability to handle deep charge/discharge cycles without much loss in cell power output over the life span.

AGM Batteries

Absorbed Glass Mat (AGM) batteries are a type of lead-acid deep cycle battery that has been becoming increasingly popular to power electric vehicles and other applications over the past few years. AGM batteries are made with a proprietary mixture of sulfuric acid, lead oxide and a mat of combined glass fibers.

The advantages of AGM batteries include: maintenance-free operation, faster recharging times when compared to conventional flooded lead-acid (FLA) batteries, increased current capacity, longer lifespan and better vibration resistance. They also produce substantially lower levels of gassing and hydrogen emissions than other types of batteries, making them much more suitable for enclosed spaces such as RVs or marine vessels.

Safety is an important factor to consider when selecting an AGM battery as they can’t leak acid when in use or mounted on its side. This makes them a great choice for fragile environments or people with small children who need to be kept out of harm’s way. Additionally, their superior energy density means that given the same size class, an AGM battery will often have more amp hours available than its FLA counterpart. This means that users can get longer run time from their electric vehicles before needing to recharge them.

Choosing the right battery for your RZR can be a daunting task. You may have questions such as what size, or capacity the battery should be, or which type is best.

There are a few factors you should consider when selecting a battery, such as its power requirements, durability and ease of maintenance.

Let’s get into the details of these factors and what you should look for in a good battery for your RZR.

Battery Capacity

When selecting a battery, it’s important to consider the capacity of the battery. The capacity of a battery is measured in Amp-hours (Ah) and this capacity indicates the maximum amount of energy that can be stored in the battery. Generally, increased capacity will result in increased cost, so it is important to choose a battery that has a suitable capacity for your specific application.

In addition to choosing an appropriate Ah rating for your application, you should also pay attention to the voltage rating of your battery and ensure that it matches with any equipment or accessories you want to power. Many automotive-type batteries are rated 12 volts or higher – these are good general-purpose batteries, but depending on what you need to run specifically, may not be suitable. In some circumstances, you may wish to look into specialty batteries such as AGM (Absorbed Glass Mat) or Gel Cell batteries that offer higher performance levels than traditional lead acid batteries.

It is also important to take note of voltage drops when selecting a suitable battery as well – especially if running multiple voltages at once or powering sensitive electronics or devices. You should also consider looking into sealed lead acid or lithium ion batteries for applications requiring frequent deep cycling – such as electric scooters and off-road vehicles – since these types are better suited for this kind of use than traditional flooded lead acid style ones are. Finally, take time to research different brands before purchasing a new battery – read reviews from other users about their experiences with various models and brands and factor these ratings into your decision as well!

Battery Voltage

When selecting a battery for your recreational vehicle such as a side-by-side, there are many factors to consider. Knowing the voltage of the battery and the corresponding discharge rate is essential for making sure that your vehicle has the power capacity to perform your desired activities.

Typically side-by-side vehicles require either 12V or 14V batteries. A 12V battery typically contains 6 lead acid cells of 2.1 volts each, and a 14V battery contains 7 cells of 2 volts each. The choice between 12V and 14V batteries will depend on the type of motor you have in your vehicle and what type of power load you need it to withstand.

12 V batteries will produce greater amperage than their 14 V counterparts as they contain more lead acid cells per pack. For instance, one 12 V battery might provide 45 Amp hours (AH) capacity while two 7 cell 14 V batteries linked together will only give about 36 AH capacity because two 7 cells result in less amperage output combined than one 12v battery does on its own due to differences in their voltages.

The AH rating provided on the label of a given product is an indication of how long it can provide usable power with given current discharge rates compared against bigger rated units which can generally deliver more power over longer periods of time before needing recharging. When choosing between different AH rated products it is important to understand what load requirements are needed for your vehicle and go with the most suitable option according to those needs while keeping in mind that bigger rated products generally cost more money upfront but may save you money in the long run due to needing less replacing over time compared against smaller rated products due lower overall current draw demand placed upon them when used for their intended purposes.

Battery Weight

Choosing the right battery for your application involves selecting a battery that is the right size, has adequate capacity, and is lightweight enough that your vehicle can handle it. When browsing batteries for your vehicle, you should carefully consider the weight of each model.

Weight is an important factor for many reasons; for example, if a battery is too heavy, it can put too much strain on the engine and suspension components of a vehicle. Additionally, if you plan to move or transport your vehicle frequently, you may want to look for a lighter-weight battery to make the job easier.

Typically, lithium-ion batteries offer the best combination of light weight and durability compared with lead acid batteries. Lead acid batteries are often heavier than their lithium-ion counterparts and can be easily damaged from vibration or shock.

Knowing exactly how much weight your vehicle can handle in terms of a battery will help you narrow down your selection of favorites!

Battery Life

When it comes to choosing the best battery for your vehicle, you want to consider the overall battery life. Battery life is measured in two ways – how long it takes to discharge the battery and how many times a battery can be charged and discharged before it needs to be replaced. When determining which type of battery is best for you, consider both of these factors.

The size of the battery also plays a role in its longevity. Smaller batteries are more efficient, using less energy so they last longer than larger batteries. It’s important to choose a size that fits your vehicle and provides enough power for your needs without being too heavy or bulky.

Other factors to consider when choosing a battery include environmental conditions, such as temperature and humidity; charging replacement time; capability of discharging quickly; current draw capabilities; internal resistance; self-discharge rate; operating temperature range; vibration resistance; and shelf life. To ensure you’re getting the best possible performance from your vehicle’s battery, consider all of these factors before you make your purchase decision.

Tips for Buying a RZR Battery

When you’re shopping for a RZR battery, there are a few important factors to consider.

First, you need to make sure the voltage and capacity of the battery are right for your machine. Most models usually require 12 volts with 120 amp hours capacity or higher, so be sure to check your owners manual before purchasing.

The running wattage of your accessories will also play a role in selecting the right battery. Accessories like winches and stereos require more watts, while lower wattage accessories can get by with fewer amps and volts. Range on electric power items like winches is typically limited without upgrading the battery size.

At least as important as size and voltage is durability. Even though you’re looking for a reliable charge, most riders also want their battery to last long-term under different conditions such as extreme temperatures and constant vibration from rough trails or offroad races. So be sure to ask about the manufacturer’s testing results when shopping for a RZR battery, including proof that it was tested in all temperatures from cold Canadian winters to scorching South Texas heat waves. Reliability should come first when it comes to choosing an off-road vehicle’s power source!
