The most famous battery in off-roading does not belong on this list. OPTIMA’s own spec sheet says the RedTop is “not recommended or warranted for use in deep cycle applications” — and winching is exactly that: a winch at full load pulls roughly 300–450 amps in long, deep draws. The previous version of this guide recommended the RedTop anyway, alongside a powersports battery and an ASIN nobody can identify. This rebuild starts from what WARN itself specifies — a fully charged battery of at least 650 CCA, with the reserve capacity to keep feeding the winch through a pull — and recommends only batteries whose makers design them for that work.
How we researched: manufacturer datasheets from OPTIMA, NorthStar, XS Power, ACDelco and Renogy, WARN’s published battery guidance, and owner reports from off-road forums. We do not test batteries. Where a number conflicts between a listing and a manual, the manual wins and the conflict is printed.
Short answer: the OPTIMA YellowTop D34/78 is the winch battery to buy — a dual-purpose AGM whose maker explicitly names trucks with winches. The NorthStar AGM34 is the heavy-duty step up. And buy reserve capacity, not just CCA.

How our score works: winch suitability (dual-purpose/deep-draw design) 30% · reserve capacity 25% · CCA vs the 650 floor 15% · warranty 15% · owner record in winching use 15%. Our Score is editorial judgement based on published specs and owner reports, not test results.
What a winch actually asks of a battery
650 CCA is the floor. WARN’s manuals and its Winch Battery Basics guidance set the minimum at a fully charged 650 CCA battery for peak winch performance, covering winches up to about 12,000 lb. CCA measures a 30-second starting burst, though — and a recovery is not a burst.
Reserve capacity is the endurance number. RC (minutes at a 25-amp draw before voltage falls) is what keeps a winch fed through a long pull, pull after pull. That is why this guide weighs RC as heavily as CCA, and why a dual-purpose or deep-cycle design beats a pure starting battery even at equal CCA. Supporting details from the same sources: winch leads are 2-gauge and should never be extended with thinner wire; keep the engine running while winching (Mile Marker’s manuals say the same); and a battery mounted on its side must be AGM — flooded cells leak.
The dual-battery answer: WARN sells a Dual Battery Control Kit for exactly this problem — the second battery shares winch and accessory loads while the main battery is saved for starting, with a manual override to parallel both. That architecture is also the only honest home for the Renogy pick below: auxiliary capacity, never the cranking battery.
Battery safety: winch cables carry starter-motor current for minutes at a time. Use the battery’s top posts for winch connections where the maker advises it (OPTIMA does — see the YellowTop section), keep terminals tight and protected, and never let a loose cable chafe against the tray.
1. OPTIMA YellowTop D34/78 — Best Overall
The YellowTop is the battery this category is named after: OPTIMA’s dual-purpose design starts the truck and tolerates the deep draws a winch makes, and OPTIMA’s own product copy names trucks with winches as a use case. 750 CCA clears WARN’s floor; 120 minutes of reserve capacity does the endurance work; and the owner record below is the strongest winching-specific one in this guide.
| Type | Dual-purpose (starting + deep cycle) AGM SpiralCell, Group 34/78 |
| CCA | 750 (870 MCA) |
| Capacity | 55 Ah |
| Reserve capacity | 120 min |
| Terminals | Dual SAE top posts + GM side terminals |
| Weight | 43.5 lb |
| Warranty | 36-month free replacement |
Pros
- Manufacturer explicitly endorses winch use
- Dual-purpose: starts and deep-cycles
- Strong, specific winching owner record
Watch-outs
- 55 Ah is modest — heavy winchers should look at the NorthStar or a dual setup
- Premium price
What owners say: On IH8MUD, owners describe the classic split — a starting battery for the engine circuits and a YellowTop for the winch and accessories — working well. A Tacoma World owner reports a 2005 YellowTop doing “great on long hard winch pulls in well below freezing temperatures” across eight years and two vehicles, and a Steel Soldiers owner ran one in a Jeep for about six years of regular winching and would buy another. One practical warning from OPTIMA via owner forums: connect winch cables to the TOP posts, not the side posts.
2. NorthStar NSB-AGM34 — Best Heavy-Duty
NorthStar’s pure-lead thin-plate AGM is the connoisseur step up: 880 CCA, the joint-best published cycle life here (400+ cycles to 80% depth of discharge) and a 4-year full warranty — the longest in this guide. Two honest caveats: the NorthStar automotive line is being folded into EnerSys/Odyssey, so treat listings as current-but-legacy stock; and the exact variant behind this listing (34 vs the near-identical 34/78) could not be confirmed — the specs differ negligibly.
| Type | Pure-lead thin-plate AGM, Group 34 |
| CCA | 880 (1,050 CA/MCA) |
| Capacity | 63 Ah |
| Reserve capacity | 133 min |
| Cycle rating | 400+ cycles to 80% DoD |
| Weight | 49 lb |
| Warranty | 4-year full |
Pros
- Highest CCA-to-size here
- 4-year full warranty
- Deep cycle rating is genuinely published
Watch-outs
- Brand being folded into Odyssey — legacy stock
- 49 lb
- AGM charging-voltage caveat (below)
What owners say: A DMCTalk owner calls his NorthStar “perhaps overkill — but has worked flawlessly over the last two years”. Tacoma World’s winch-battery thread recommends NorthStar-class AGMs for winching with one caveat worth repeating: some stock charging systems run voltages too low to keep an AGM fully topped, and a voltage booster fixes it.
3. XS Power D6500 — Best Endurance
The XS Power D6500 is an audio-world AGM that happens to carry the biggest endurance numbers here: RC 174 minutes and 86 Ah, with 968 CCA from the manual. Paperwork flag, printed as found: the listing title advertises “3,900 Amp” while XS Power’s own manual says 3,800 max amps — we use the manual’s figure. It earns its slot for rigs that run a winch and a heavy accessory load from one battery.
| Type | AGM power cell, Group 65 |
| Max amps | 3,800 (manual; listing title says 3,900) |
| CCA | 968 |
| Capacity | 86 Ah |
| Reserve capacity | 174 min |
| Weight | 53.8 lb |
| Warranty | 3-year |
Pros
- Highest reserve capacity and capacity here
- Strong CCA
- Built for sustained high-draw abuse
Watch-outs
- Audio-first design and marketing
- Listing title overstates the manual’s amp figure
- No winching-specific owner reports found
What owners say: Owner coverage for winching specifically is thin — we found none, and say so. General owner reports (Crutchfield) are positive for truck and audio duty, including one owner with two units still holding charge after nine years.
4. ACDelco Gold 48AGM — Best Value
The value pick, framed honestly: the 48AGM is a starting-class AGM, and Summit classifies its usage as starting. It still clears WARN’s 650 CCA floor with room (760 CCA) and matches the YellowTop’s 120-minute reserve capacity, which is why it can serve a light-duty winch vehicle as a compromise — just do not mistake it for a deep-cycle battery, and heavy winchers should buy the picks above.
| Type | AGM, Group 48 (H6) |
| CCA | 760 (880 CA) |
| Capacity | 70 Ah |
| Reserve capacity | 120 min |
| Weight | ~46 lb (45.6–46.9 lb across retailers) |
| Warranty | 36-month free replacement |
Pros
- Lowest price of the credible picks
- Clears the 650 CCA floor with margin
- RC matches the YellowTop
Watch-outs
- Starting-class design, not deep-cycle
- Weight figure varies by source
What owners say: General owner sentiment for starting duty is positive (a roundup of owner reviews cites a C7 Corvette owner reporting strong, consistent power). Winching-specific owner reports were not found — hence the compromise framing, not a headline recommendation.
5. Renogy Deep Cycle AGM 100Ah — Auxiliary Bank Only
The Renogy is a house-power battery — RV, solar, marine — and Renogy publishes no CCA for it because starting engines is not its job. It appears here for exactly one honest reason: as the auxiliary half of a dual-battery setup, where its 100 Ah of deep-cycle capacity feeds accessories and supports the winch bank while a real cranking battery starts the truck. Bought as your only battery, it is the wrong purchase.
| Type | Deep-cycle AGM (house power) |
| CCA | Not published — not a starting battery |
| Capacity | 100 Ah |
| Max discharge | 1,100 A for 5 seconds (datasheet) |
| Weight | 63.9 lb |
| Warranty | 2-year prorated |
Pros
- 100 Ah of true deep-cycle capacity
- Ideal auxiliary-bank role
- Low self-discharge
Watch-outs
- No CCA rating — never the cranking battery
- Heavy
- Prorated warranty
What owners say: Owner reports sit in its own world: an Amazon owner review reports a pair outperforming pricier batteries over a 14-day dry-camping trip while struggling to start a built-in generator — exactly the behaviour its datasheet predicts. No winching use was reported anywhere, and none is claimed here.
What was removed from this guide, and why
The OPTIMA RedTop — removed because its maker says it is not designed or warranted for deep-cycle work, and an OPTIMA representative has told Jeep owners the same about winching specifically. A Chrome Pro iGel powersports battery (YTX14-BS class, for ATVs and motorcycles) — removed as a category error. And one listing could not be identified as any product at all after repeated checks — removed rather than guessed at. A battery guide that cannot say these things plainly is not worth following; the sizing advice lives in our winch power requirements guide.
Winch battery FAQ
What size battery does a winch need?
WARN’s floor is a fully charged 650 CCA battery for winches up to about 12,000 lb — plus the reserve capacity to sustain the pull. Every cranking pick in this guide clears the floor; the dual-purpose designs are the ones built for the work.
CCA or reserve capacity — which matters?
Both, for different jobs: CCA starts your engine and covers the first seconds; reserve capacity decides whether the tenth minute of winching still has voltage behind it. For a winch battery, RC is the number buyers under-read.
Can a starting battery run a winch?
It can, briefly and at a cost — starting batteries are built for shallow, short bursts, and deep draws shorten their lives. That is the whole RedTop lesson: use a dual-purpose or deep-cycle design for the winch side.
Do I need a dual-battery setup?
Only if you winch often, run heavy accessories, or cannot risk a no-start after a recovery. WARN’s control kit exists for exactly that split: winch loads on the auxiliary, starting guaranteed on the main.
Why does cable gauge matter?
A winch can draw 300–450 amps at full load; thin or extended cables drop voltage, and a starved winch is a weak, hot winch. WARN supplies 2-gauge leads for a reason — do not extend them with thinner wire.
Our verdict
Buy the YellowTop for the winch battery its maker endorses for winches, the NorthStar for heavy-duty headroom, the XS Power when one battery must feed everything, and the ACDelco as the honest budget compromise. Add the Renogy only as auxiliary capacity in a dual setup. And whichever you buy, read the reserve capacity line before the CCA line — that is the difference between a battery that starts your truck and a battery that finishes your recovery.
