Quick answer: The best 12 volt golf cart battery for most four-battery 48V carts is the Trojan T-1275, rated at 150 Ah (20-hour), 70 minutes at 75 amps and 85 lb on Trojanâs own spec page, at $1,798.95 for a four-pack with free shipping at Golf Cart Tire Supply. The best-value set is the Crown CR-GC150 four-pack at $1,368.95, which carries the same 150 Ah rating and a 24-month warranty. Before you buy, know that four 12-volt batteries hold less energy than six 8s: US Battery puts the difference at 7,440 versus 8,160 watt-hours, almost 10% less range.
Twelve-volt batteries are the four-battery way to build a 48-volt cart (and the six-battery way to build a 72-volt one). They are bigger and heavier than the 6V and 8V golf cart batteries most guides cover, and the search results for â12 volt golf cart batteryâ are full of small lithium packs for electric push carts that wonât run a cart at all. This guide compares the five GC12 batteries we would actually put in a cart in 2026, with specs taken from manufacturer data sheets and prices from retailer pages checked on October 30, 2026.

Prices are before sales tax and core charges. âSet of 4â is what a four-battery 48-volt cart needs; a 72-volt cart needs six.
1. Trojan T-1275 â Best Overall
Trojan T-1275 12V Flooded Deep-Cycle Battery (GC12)
- Trojan's spec page lists the T-1275 at 120 Ah at the 5-hour rate, 134 Ah at 10 hours, 150 Ah at 20 hours and 166 Ah at 100 hours, with 70 minutes at 75 amps, 102 minutes at 56 amps and 280 minutes at 25 amps.
- It weighs 85 lb and measures 12.96 x 7.13 x 11.13 inches. That is the same 85 lb per battery Golf Cart Tire Supply quotes for the factory batteries in a lead-acid EZGO RXV.
- Golf Cart Tire Supply sells a four-pack for a 48V cart at $1,798.95 (list $2,199.99) with free shipping and an 18-month Trojan warranty, about $450 per battery. Single batteries were listed from $356.40 at A1 Solar Store to $365.99 at Continental Battery, before freight or pickup.
- Trojan publishes all three runtime ratings (75, 56 and 25 amps), so you can line it up against any other GC12 on the same terms.
2. Crown CR-GC150 â Best Value Set
Crown 12-Volt Golf Cart Battery CR-GC150 (4-Pack, 48V)
- Crown's golf and utility spec sheet lists the CR-GC150 at 150 Ah at 20 hours and 120 Ah at 5 hours, the same as the T-1275, with 61 minutes at 75 amps, 103 at 56 amps and 243 at 25 amps, and 81 lb.
- Golf Cart Tire Supply's four-pack is $1,368.95 (list $1,899.99) with free shipping, $430 less than the Trojan four-pack, and it carries a 24-month Crown warranty versus 18 months on the Trojan set. The retailer lists the batteries as made in the USA.
- The trade-off is runtime under heavy load: 61 minutes at 75 amps against the Trojan's 70, about 13% less, and 243 versus 280 minutes at 25 amps.
- Walmart marketplace listings titled "Crown T-1275" mix Crown's brand with Trojan's model number. Crown's own part number is CR-GC150; the step-up CR-GC155 is rated 155 Ah and 75 minutes at 75 amps.
3. Duracell Ultra GC12 (Batteries Plus) â Cheapest Walk-In Battery
Duracell Ultra 12V 150Ah Flooded Golf Cart Battery (Batteries Plus SLIGC12V-ELPT)
- Batteries Plus lists it at $319.99, rated 150 Ah with 280 minutes of reserve capacity, 86 lb, in the GC12 case with a 12-month free replacement warranty.
- A set of four is $1,279.96 before the refundable core deposit, which Batteries Plus lists at up to $27 per battery ($108 on a set of four if you don't bring the old ones).
- It is the cheapest new GC12 we found at a walk-in store, which matters when a single battery fails mid-season and the rest of the pack is young.
- Batteries Plus doesn't publish a 75-amp runtime, so you can't compare it with the Trojan or Crown on the number that matters most for a cart.
4. US Battery US 12VRX XC2 â Most Flooded Runtime
US Battery US 12VRX XC2 12V Flooded Deep-Cycle Battery (GC12)
- US Battery rates it at 155 Ah at the 20-hour rate, 77 minutes at 75 amps and 292 minutes at 25 amps, the longest 75-amp runtime of any flooded GC12 in this guide.
- US Battery recommends it for the Club Car Precedent Champion's four-battery 48V pack as "a great compromise between daily and occasional use."
- The cheaper US 12VE XC2 in the same case is rated 145 Ah and only 62 minutes at 75 amps, so check which model a dealer is quoting.
- US Battery sells through distributors rather than direct, and no retail price is published. Use its distributor locator and compare the quote against the Trojan four-pack.
5. Duracell Ultra GC12 AGM (Batteries Plus) â Best No-Watering
Duracell Ultra 12V 150Ah Sealed AGM Golf Cart Battery (Batteries Plus SLIGC12VAGM)
- A sealed, spill-proof AGM battery in the GC12 case with 320 minutes of reserve capacity and a listed weight of about 92.6 lb, per Batteries Plus.
- Batteries Plus listed it at $464.99; another listing for the same part showed $491.99 including the $27 core deposit and no ship-to-home. A set of four is $1,859.96 before cores.
- For comparison, US Battery's sealed US AGM 12V150 is rated 150 Ah, 90 minutes at 75 amps and 93 lb, and Trojan's heavier T1275-AES AGM (146 Ah, 105 lb) is validated at 1,200 cycles at 100% depth of discharge versus 400 for standard AGM, per Trojan.
- No watering, no acid on the tray and lower self-discharge in storage, but your 48V charger needs an AGM profile and the set costs about $60 more than the Trojan flooded four-pack.
Also worth a look: Interstateâs GC12-HCL-UTL lists at $374.95 (SRP) with 150 Ah at the 20-hour rate and a 12-month free replacement warranty, sold through Interstate dealers.
Which golf carts use 12 volt batteries?
- Four batteries in a 48V cart = 12-volt. The lead-acid EZGO RXV uses four (85 lb each, per Golf Cart Tire Supplyâs RXV conversion guide), and US Battery lists the Club Car Precedent Champion as a four-GC12 cart.
- Six batteries in a 72V cart = 12-volt. Golf Cart Tire Supply sells the same Crown battery as a six-pack for 72V carts at $1,898.95 (480 lb total).
- Six batteries in a 48V cart = 8-volt, the standard Club Car DS and Precedent layout. See our 8 volt golf cart battery guide. Six batteries in a 36V cart = 6-volt, covered in our 6 volt golf cart battery guide.
- Count the vent caps. Each lead-acid cell makes about 2 volts, so a 12-volt battery has six caps, an 8-volt battery four and a 6-volt battery three. A 12V golf cart battery is also visibly longer: about 13 inches against roughly 10 inches for 6V and 8V cases.
- Check resting voltage. A healthy 12-volt battery reads about 12.5-12.6 volts at rest. Our battery tester guide covers load testers that handle 12V batteries.
The wrong 12 volt battery: push carts, cars and accessories
Search â12 volt golf cart batteryâ and many of the results arenât cart batteries at all. RELiONâs RBGT-22, for example, is a 12V 22 Ah lithium battery for electric golf push carts that weighs about 6 lb and plugs in with an Anderson connector, per RELiONâs product spec guide. A 22 Ah battery holds about one-seventh of the amp-hours of a 150 Ah GC12, and it canât be wired into a cartâs 48V pack. Car and marine starting batteries are the other mix-up: they come in different case sizes and are built for short cranking bursts, not hours of deep discharge.
If you want 12 volts for lights, a radio or a USB charger on a 48V cart, you donât need a 12V battery either. A voltage reducer steps the whole pack down to 12V and draws evenly from all four batteries instead of draining one.
Runtime: 12-volt batteries are rated at 75 amps (check the label)
Unlike 8-volt batteries, which Trojan rates at 56 amps, 12-volt golf cart batteries are usually compared on minutes at 75 amps, the closest figure to real cart use. The numbers below come straight from manufacturer data sheets:
| Battery | 20-hr rate | 5-hr rate | Minutes at 75 A | Minutes at 56 A | Minutes at 25 A | Weight |
|---|---|---|---|---|---|---|
| Trojan T-1275 | 150 Ah | 120 Ah | 70 | 102 | 280 | 85 lb |
| Crown CR-GC150 | 150 Ah | 120 Ah | 61 | 103 | 243 | 81 lb |
| Crown CR-GC155 | 155 Ah | 125 Ah | 75 | 110 | 286 | 88 lb |
| US Battery US 12VRX XC2 | 155 Ah | Not listed | 77 | Not listed | 292 | Not listed |
| US Battery US 12VE XC2 | 145 Ah | Not listed | 62 | Not listed | 270 | Not listed |
| US Battery US AGM 12V150 (AGM) | 150 Ah | 133 Ah | 90 | 120 | 323 | 93 lb |
| Trojan T1275-AES (AGM) | 146 Ah | 124 Ah | Not listed | 113 | 295 | 105 lb |
Sources: Trojan product pages, Crownâs golf and utility battery spec sheet, US Battery product pages, all checked October 30, 2026.
Watch the label on marketplace listings. At least one Walmart marketplace listing for the Crown CR-GC150 gives its runtime as â103 minutes at 75 amps.â Crownâs own sheet puts 103 minutes in the 56-amp column and 61 minutes at 75 amps. Running 103 minutes at 75 amps would mean pulling about 129 Ah out of a battery rated for only 120 Ah at the far gentler 5-hour rate, which a lead-acid battery canât do. Compare the CR-GC150 on its 61-minute figure.
Four 12s, six 8s or six 12s: what the layout costs you
Using Trojanâs own 20-hour ratings:
| Layout | Example battery | Pack energy (20-hr rate) | Pack weight |
|---|---|---|---|
| 48V: four 12-volt | Trojan T-1275 (150 Ah) | 7.2 kWh | 340 lb |
| 48V: six 8-volt | Trojan T-875 (170 Ah) | 8.2 kWh | 378 lb |
| 72V: six 12-volt | Trojan T-1275 (150 Ah) | 10.8 kWh | 510 lb |
A four-battery 48V pack is 38 lb lighter than a six-battery one and has fewer cable connections to corrode, but it carries about 12% less energy. US Batteryâs VP of marketing, Mike Wallace, ran the same comparison with his companyâs batteries: six 8-volt units hold 8,160 watt-hours against 7,440 for four 12-volt units, âalmost a 10% reduction in driving range.â He also noted that switching a six-battery cart to four 12s means modifying the battery tray and hold-downs, so it rarely pays off. Trojanâs spec page lists the T-1275 at 1.99 kWh, but that uses the 100-hour rating (12 V x 166 Ah); at the 20-hour rate it is 1.8 kWh per battery.
How to choose a 12 volt golf cart battery
- Replace all four (or all six). A series pack is only as strong as its weakest battery, and one new battery next to three worn ones gets over-worked. If the set is under a year old and one battery failed a load test, a single matched replacement is reasonable.
- Size the charger to the pack. Trojanâs rule is a charge rate of 10-13% of the 20-hour rating, about 15-20 amps for a set of 150 Ah batteries. Four 12s need a 48V charger, six need a 72V one. Our golf cart charger guide covers 48V smart chargers, including AGM-compatible models.
- Plan the lift. At 81-93 lb for the picks above, a GC12 outweighs every 6V and 8V battery in our other battery guides. Golf Cart Tire Supplyâs RXV guide tells owners to be extra careful with the small lifting tabs on the 85 lb batteries and to use a battery strap.
- Keep up with water. A 48V pack of four 12s has 24 cells to check, the same as six 8s. Trojan says to check monthly until you know how fast your batteries use water, and to top up after charging. Our battery maintenance checklist covers the routine, and a single-point golf cart battery watering kit makes it a two-minute job (note that Trojan says no watering system is available for the T-1275 Plus).
- Donât run them flat. Trojan recommends discharges of 50% or less and calls 80% the maximum safe discharge. Our battery lifespan guide explains why deep cycling shortens pack life.
- Swap tired cables at the same time. The longer GC12 case often means different cable lengths from a six-battery layout; see our battery cable guide and battery box guide.
Lead-acid or lithium?
A new set of four 12-volt batteries runs about $1,280 at the low end (Duracell Ultra at Batteries Plus), $1,369 for the Crown four-pack, $1,799 for Trojan T-1275s and $1,860 for sealed AGM. Golf Cart Tire Supply notes that a single 48V lithium pack for the RXV weighs about 100 lb against 340 lb for the four lead-acid batteries it replaces, and it needs no watering. If you plan to keep the cart for years, price a conversion in our best lithium golf cart battery guide first. If youâre selling in a year or two, a fresh lead-acid set is the cheaper move.
The bottom line
For a four-battery 48-volt cart you plan to keep, the Trojan T-1275 is the 12-volt battery to beat: 150 Ah at the 20-hour rate, 70 minutes at 75 amps and a spec sheet that publishes every rating. The Crown CR-GC150 four-pack saves $430 with the same amp-hour rating and a longer 24-month warranty, at the cost of about 13% less runtime under heavy load. The Duracell Ultra GC12 at $319.99 is the walk-in fix for a single failed battery, the US Battery US 12VRX XC2 has the longest flooded 75-amp runtime if your dealer can price it well, and the sealed Duracell Ultra GC12 AGM is the pick if you never want to add water again. When you compare runtime, compare minutes at 75 amps, and check which column a listingâs number actually came from.
