A dead battery on a Polaris Ranger 570 is more than an inconvenience. It usually shows up on a cold morning, miles from the trailer, after the winch, lights, and a season of short rides have quietly drained the cells. The 570 uses a 12V U1 footprint battery, and the factory unit is fine until it is not, which is why so many owners go looking for a stronger replacement.
We pulled the seven batteries that 570 owners buy most often, checked fitment against the U1 tray, and weighed each on the things that actually matter on a side by side: cold cranking power, how it holds up to winch and accessory loads, vibration tolerance on rough trails, and how long it lasts before it leaves you stranded. Below are our top picks, ranked best first, with honest notes on where each one falls short.

1. NOCO NLP14 Lithium Powersports Battery: Best Overall
The NOCO NLP14 is the pick we would put in our own Ranger 570 first. It is a lithium iron phosphate battery that delivers 500 cranking amps, far more than the 570 needs to fire its single cylinder, and it keeps that punch even after the machine has been parked for a few weeks. The included foam spacers and the dual terminal layout let it sit tight in the factory U1 tray without rattling, which matters on a UTV that spends its life over washboard and rock.
The real weakness is the chemistry itself. Lithium does not like to be charged in freezing weather, and the onboard BMS will limit charging when the pack is very cold, so deep winter riders need to warm the machine before expecting a full charge. It also wants a lithium aware charger for maintenance. If you can live with those habits, the light weight, fast cranking, and slow self discharge make it the most complete battery here.
- Lithium iron phosphate chemistry stays light and holds voltage under heavy winch and light loads
- Ships with foam spacers and dual terminal positions to lock into the Ranger 570 U1 tray
- Integrated battery management system guards against over discharge, over charge, and shorts
Pros: Drops a large amount of weight versus a flooded battery; Strong, consistent cranking even after sitting between rides; Self discharge is slow, so it survives off season storage well
Cons: Lithium needs a compatible charger and does not love freezing temperatures during charging; Sits at the premium end of the lineup
2. Antigravity Batteries ATX30-HD Lithium: Best Lithium for Heavy Accessories
If your 570 wears a winch, a snow plow, or a row of light bars, the Antigravity ATX30-HD is built for exactly that abuse. This is a heavy duty lithium pack with serious output, and the standout trick is its RE-START technology, which can hold back a small reserve charge and let you wake the battery with a button if you flatten it leaving lights on. On a work machine that asks a lot of its electrical system, that safety net is genuinely useful.
The honest caveat is that this is more battery than a stock Ranger 570 will ever use. The cranking demand of the single cylinder is modest, so the extra capacity and output are wasted unless you are running real accessory loads. It also carries Antigravity pricing and the usual lithium charging rules. Bought for the right build it is brilliant, but a bone stock 570 does not need it.
- Heavy duty lithium pack built to feed winches, plows, and full light bars
- RE-START feature can reserve a reset charge if the battery is drained too far
- Compact and very light, with strong cranking for the 570 single cylinder
Pros: Massive cranking headroom for accessory heavy builds; Reserve start function can save a ride after an accidental deep drain; Among the lightest options for the power on offer
Cons: Premium pricing and a premium charger requirement; Overkill for a stock 570 with no add ons
3. Polaris OEM Battery 4011138: Best OEM Replacement
For owners who simply want the machine back to the way the factory built it, the Polaris OEM 4011138 is the safe answer. It is a genuine sealed AGM battery designed to drop into the Ranger 570 with the correct dimensions, terminal layout, and venting, so there is no spacer fiddling and no question about fit. It ships charged and sealed, and it behaves exactly the way the original did, which is reassuring if you have had bad luck with mystery batteries.
The trade off is that you are paying for the Polaris badge to get average performance. Its cranking output and service life are solid but unremarkable, and several third party AGM units match it for less. It is the right pick when fitment certainty and warranty added security matter more than squeezing out extra cold cranking amps or shaving weight.
- Genuine Polaris part designed to match the original tray, terminals, and venting
- Sealed AGM build that ships ready to install with no acid filling
- Plug and play fit that avoids any spacer or terminal guesswork
Pros: Exact factory fitment with zero modification; Proven on Polaris machines, so behavior is predictable; Sealed AGM design is maintenance free
Cons: Cranking and lifespan are average rather than class leading; Costs more than equivalent third party AGM units
4. Weize YTX20L-BS High Performance AGM: Best Value AGM
The Weize YTX20L-BS is the battery we point budget minded 570 owners toward. It is a sealed AGM unit that arrives factory activated and charged, so you bolt it in and go with no acid handling. The AGM build shrugs off the vibration and the occasional steep angle that come with side by side life, and it cranks the 570 reliably in cold weather, which is all most owners are really asking for.
It is not perfect. Being a lead acid AGM, it is noticeably heavier than the lithium picks, and while its lifespan is respectable it will not match a quality LiFePO4 pack kept on the right charger. But for an honest, no drama replacement that does the job and respects your wallet, the Weize is hard to argue with and represents the strongest value in the lineup.
- Sealed AGM construction that resists spills and vibration on rough trails
- Ships factory activated and charged, ready to bolt in out of the box
- Widely used across UTV and powersports applications with strong owner reports
Pros: Excellent value for a sealed AGM battery; Maintenance free and spill proof for trail vibration; Reliable cold starts for a stock 570
Cons: Heavier than any lithium option here; Lifespan is good but not the longest in the group
5. Mighty Max Battery ML-U1-CCAHR: Best for Accessory Power
The Mighty Max ML-U1-CCAHR earns its spot for owners who run accessories and want a battery that can take some deep cycling without complaint. It uses a true U1 case, so it sits in the Ranger 570 tray without spacers, and its 320 cranking amp rating gives a little extra margin over a basic stock replacement. The AGM construction lets it handle the partial discharge that comes with sitting and running lights or a radio without quickly killing the plates.
Where you need to pay attention is the terminal layout. Depending on your cable lengths, you may want to confirm the post orientation matches your routing before ordering, since U1 batteries vary. It is also a lead acid unit, so it carries the usual weight penalty over the rear of the machine. Those points aside, it is a tough, flexible battery that punches above its modest reputation.
- True U1 case that fits the Ranger 570 tray directly without adapters
- Higher cranking amp rating than many stock replacements
- AGM design tolerates partial deep cycling for accessory heavy use
Pros: Generous cranking amps for a sealed AGM; Handles accessory and light deep cycle duty well; Sealed and maintenance free
Cons: Terminal orientation may need checking against your cable routing; Heavier unit that adds weight over the rear axle
6. ExpertPower U1 Lithium LiFePO4 Battery: Best Lightweight Lithium
The ExpertPower U1 LiFePO4 is the choice for owners who mainly want to cut weight and are not chasing the highest cranking number. It is a lithium iron phosphate battery in a proper U1 case, so it slots into the Ranger 570 tray as a drop in, and the built in BMS handles balancing and protection so you do not have to think about it. The weight savings over an AGM are immediately obvious when you lift it into the tray.
Its limitation is that it is a general purpose U1 lithium rather than a dedicated powersports cranking battery, so its cold cranking output sits below the NOCO and Antigravity picks. For a stock or lightly accessorized 570 that is perfectly adequate, but heavy winch users should look higher up the list. As with any lithium, it also wants a compatible charger and does not like charging in freezing conditions.
- LiFePO4 chemistry in a drop in U1 case for the Ranger 570 tray
- Built in BMS manages charging, balancing, and discharge protection
- Dramatic weight savings over an equivalent AGM battery
Pros: Very light, which is noticeable on a small UTV; Flat discharge curve holds cranking voltage well; Long potential cycle life when charged correctly
Cons: Cranking output trails the dedicated powersports lithium picks; Needs a lithium friendly charger and warmth to charge in winter
7. Banshee YTX20L-BS AGM Powersports Battery: Best for Cold Starts
The Banshee YTX20L-BS rounds out our list as a focused cold start option. It is a sealed AGM powersports battery with a high cranking amp rating, and that is exactly what you want when a frosty morning makes the 570 sluggish to turn over. It comes sealed and charged, installs with no maintenance, and the absorbed glass mat design helps it hold up to the constant trail vibration that loosens lesser batteries over time.
The honest notes are familiar for the category. It is lead acid, so it is among the heaviest batteries here, and owner reports on long term consistency are a little mixed, which makes it worth registering the warranty as soon as it arrives. Taken for what it is, an affordable AGM that prioritizes cranking grunt over weight, it is a dependable way to make sure your Ranger 570 fires up when the temperature drops.
- High cranking amp AGM built for confident cold weather starts
- Sealed and pre charged so it installs without maintenance
- Rugged plates and absorbed mat design for vibration resistance
Pros: Strong cold cranking for a lead acid battery; Sealed, spill proof, and maintenance free; Good value for the cranking power on offer
Cons: Lead acid weight is the heaviest tier here; Quality control reports vary, so register any warranty promptly
Frequently Asked Questions
What size battery does a Polaris Ranger 570 take?
The Polaris Ranger 570 uses a 12V battery in the U1 footprint, the same general case size found on many UTVs and riding mowers. The factory unit is a sealed AGM, and the OEM part most commonly referenced is the Polaris 4011138. When shopping, confirm the battery is a U1 case (roughly 7.7 by 5 by 6.9 inches) and that the terminal positions match your cable routing. Many powersports batteries listed as YTX20L-BS or U1 will fit the tray, but always check the posts and any included spacers so the battery locks in without shifting on rough trails.
Is a lithium battery worth it for a Polaris Ranger 570?
For most owners, yes, with a couple of caveats. A lithium iron phosphate battery like the NOCO NLP14 saves a meaningful amount of weight, cranks strongly, and holds its charge far better during off season storage, so it is less likely to be dead when you pull the machine out in spring. The trade offs are that lithium needs a compatible charger and resists charging in freezing temperatures, so deep winter riders need to plan around that. If you ride in extreme cold and never warm the machine, a quality AGM can be the simpler choice.
Why does my Ranger 570 battery keep dying?
Repeated dead batteries usually come from one of a few causes. Short rides do not give the charging system time to replace what starting and accessories drew out, so the battery slowly falls behind. Parasitic draws from accessories, a winch, or aftermarket electronics can drain it while parked. Loose or corroded terminals reduce charging, and an aging battery simply loses its ability to hold a charge. Test the charging system, clean and tighten the terminals, and put the battery on a maintainer between rides. If it still will not hold a charge, the battery itself is likely worn out.
Can I use a regular car battery charger on my Ranger 570 battery?
For a standard AGM or flooded U1 battery, a normal automotive charger or maintainer set to a low amperage AGM mode works fine, and a trickle charger is ideal for keeping it topped up over winter. For a lithium battery you should use a charger that has a dedicated lithium or LiFePO4 setting, because a standard lead acid profile can overcharge or improperly balance a lithium pack. Avoid high amp fast chargers on small powersports batteries, since the low capacity means a gentle charge is safer and better for long term life.
How long should a Polaris Ranger 570 battery last?
A quality AGM battery typically lasts around three to five years in a Ranger 570, while a well maintained lithium iron phosphate battery can last considerably longer because of its higher cycle life. Real world lifespan depends heavily on care. Letting the battery sit discharged, exposing it to extreme heat, and frequent deep drains all shorten its life, while keeping it on a maintainer between rides and avoiding deep discharges extends it. If your battery is struggling to crank after two or three seasons, it is reasonable to plan a replacement before it strands you.
Our Verdict
Our top pick for the Polaris Ranger 570 is the NOCO NLP14, a lithium battery that combines strong, consistent cranking with light weight and excellent storage behavior, making it the most complete all round choice for the machine. If you run a winch, plow, or heavy lighting, the Antigravity ATX30-HD is the runner up and the smarter buy, with the extra output and a reserve start feature built for accessory heavy work. Owners who simply want guaranteed factory fitment should reach for the Polaris OEM 4011138, while the Weize YTX20L-BS remains the standout value for a dependable AGM replacement.
