Which Battery is Best for Your UTV: AGM or Lithium?
When you're hitting the trails or tearing through dunes in your UTV, your battery choice is crucial. Whether you're powering essential electronics, lighting systems, or even aftermarket accessories like winches and sound systems, the right battery makes all the difference. Two of the most common options for UTV owners are AGM (Absorbed Glass Mat) and Lithium-ion batteries. Each has its own strengths and weaknesses, so let’s break it down.
AGM Batteries: The Reliable Workhorse
AGM batteries are well-known in the UTV world for their durability and dependability. They're a type of lead-acid battery but use a special glass mat that absorbs the electrolyte, making them spill-proof and highly efficient in terms of power delivery.
Why Choose AGM?
- Cost-effective: AGM batteries tend to be more affordable than lithium-ion batteries, making them a great option for those looking to balance performance with cost.
- Durability: They’re rugged and built to withstand heavy vibrations and impact, perfect for offroading.
- Deep-cycle performance: AGM batteries can deliver a steady supply of power over a long period, which is important if you’re running winches or extra lights.
- No maintenance: AGM batteries are sealed, meaning no water topping or maintenance is needed.
Drawbacks of AGM
AGM batteries, while tough, are heavier than their lithium counterparts. They also tend to have a shorter lifespan compared to lithium-ion, meaning they may need replacement sooner if you're a hardcore rider putting in long hours on rough terrain.

Lithium Batteries: The Lightweight Powerhouse
Lithium-ion batteries are becoming increasingly popular among UTV enthusiasts for their lightweight design and exceptional energy density. These batteries offer a high level of efficiency and have a significantly longer lifespan than AGM batteries.
Why Choose Lithium?
- Weight savings: Lithium-ion batteries weigh significantly less than AGM batteries, which can make a noticeable difference in the performance and handling of your UTV.
- Longer lifespan: On average, lithium batteries last up to 2-4 times longer than AGM batteries, saving you money in the long run.
- Consistent power output: Lithium batteries maintain a steady voltage even when running low on charge, ensuring optimal performance throughout their lifespan.
- Fast charging: Lithium batteries charge quicker than AGM, which can be a major advantage when you're preparing for the next adventure.
Drawbacks of Lithium
While lithium-ion batteries come with a range of benefits, they are more expensive upfront. Additionally, they are more sensitive to extreme temperatures, and their performance can be affected in cold weather conditions without an internal heating system.

Which is Best for Your UTV?
The choice between AGM and lithium depends largely on your budget and the type of performance you’re looking for. If you're an occasional weekend rider who values durability and affordability, AGM might be your go-to. However, if you’re looking to minimize weight, extend battery life, and don’t mind the higher initial investment, lithium-ion batteries are hard to beat.
Dual Battery Kits: Power Up for Extensive Accessories
If you're running a bunch of aftermarket accessories—like light bars, winches, GPS units, sound systems, or additional cooling fans—your stock battery might not cut it. That’s where dual battery kits come into play. A dual battery setup can help you power more accessories without draining your primary battery, ensuring your UTV stays running strong even when fully loaded.
Benefits of Dual Battery Kits
- Power distribution: With a second battery dedicated to your accessories, your main battery stays charged and ready for starting your UTV, reducing the risk of getting stranded.
- Longer run times: Dual batteries provide more available power, so you can run multiple accessories for extended periods without worrying about depleting your power supply.
- Accessory management: A dual battery system allows you to isolate your accessories from your main battery, improving battery management and preventing overloading your electrical system.
Key Features to Look For in a Dual Battery Kit
- Automatic isolators: These devices separate your starting battery from your accessory battery, ensuring your starting battery is always charged.
- High-quality wiring: Heavy-duty wiring ensures a reliable connection between the two batteries and the rest of your electrical system.
- Compact design: Look for kits that don’t take up too much space or add too much weight to your UTV, especially if you’re concerned about performance.
A dual battery kit is a must-have for riders who frequently use multiple power-draining accessories or venture into remote areas where reliable power is essential.

Battery Maintenance: Keep Your Power Source in Top Shape
No matter which battery type you choose, maintaining it properly is essential to ensuring it lasts as long as possible. A common tool for UTV owners is a trickle charger, especially when the UTV is stored for extended periods.
Why Use a Trickle Charger?
A trickle charger maintains your battery at an optimal charge level when not in use. UTVs that sit for weeks or months can experience battery drain, which can lead to a dead battery the next time you go for a ride. A trickle charger ensures that your battery stays charged without overcharging it, which is a risk with some conventional chargers.
How to Use a Trickle Charger Effectively
- Connect properly: Always connect the charger’s positive clamp to the battery’s positive terminal and the negative clamp to the negative terminal.
- Use in a well-ventilated area: Especially important for lead-acid batteries like AGM, which may release gases during charging.
- Check the status: Many modern trickle chargers have LED indicators that show the charging status, so you know when the battery is topped up.
Key Features of a Good Trickle Charger
- Smart charging: Opt for a charger with automatic shutoff and float-mode monitoring to prevent overcharging.
- Compatibility: Make sure the charger is compatible with both AGM and lithium batteries if you have multiple types in your garage.
- Weatherproof design: If your UTV is stored outdoors or in a humid environment, invest in a weather-resistant charger for longevity.

Choosing between AGM and lithium batteries comes down to your individual needs. While AGM is reliable and affordable, lithium offers superior performance and lifespan. For UTV enthusiasts running multiple accessories, a dual battery kit ensures you won't run out of juice when you need it most. Finally, maintaining your battery with a trickle charger is the best way to ensure it’s ready to go when adventure calls.
When upgrading your UTV’s power system, choosing the right products will keep your ride ready for whatever the trail throws at you.
