Best 12 volt golf cart batteries: four for a 48V cart

If your cart has four batteries under the seat and runs at 48 volts, you need 12 volt golf cart batteries, and the Trojan T-1275 is the one to buy if the budget allows. The Interstate GC12 is the one to buy if it does not. Either way, buy four of the same brand on the same day; a mixed set charges unevenly and dies early.

The golf cart batteries hub covers the rest of the category. If you are not sure which voltage or how many slots you have, the 48 volt battery page walks through the six-8V, four-12V and eight-6V layouts, and the battery calculator will tell you whether a flooded set or lithium is the cheaper ten-year answer for the way you drive.

Which carts use four 12V batteries

The EZGO RXV, from 2008 on, left the factory with four 12V batteries, usually Trojan T-1275s or an equivalent. That is the main reason the GC12 case exists in golf cart sizes at all. The Club Car Precedent ran four 12V from its 2004 launch until the i2 battery bucket arrived in mid-2008, and the 2007 to 2010 Yamaha Drive (G29) also came with four 12V as standard; Yamaha offered a six-8V tray as an option from about 2008 and fitted a floor pan that takes either layout from the 2011 model year. EZGO sells a six-battery tray for the RXV, so an RXV you are looking at may have been converted; count before you order.

Everything else at 48V came with six 8V: the Club Car DS from 1995, the Precedent from mid-2008, the Onward and Tempo, the EZGO TXT48 from 2010, and the Yamaha G19, G22, 2011 and later Drive and Drive2. Yamaha also offers eight 6V as a long-range option on the Drive and Drive2. Those trays will also hold four 12V if you move the hold-downs, which is the budget route some owners take. The fitment finder confirms your layout from make and year.

Why four 12V gives you less range than six 8V

Every golf cart battery in the GC family sits in a case about 10 by 7 inches and 11 to 12 inches tall. A 6V battery fills that case with three cells. An 8V fills it with four. A 12V fills it with six. Same lead, same box, more partitions, so each cell in a 12V gets less plate area, and plate area is capacity.

Put numbers on it. The T-1275 is rated 150Ah at the 20-hour rate. Four of them at 48V is 7.2 kWh. Six T-875 8-volts at 170Ah is 8.2 kWh. Eight T-105 6-volts at 225Ah is 10.8 kWh. A four-12V cart gives up about 12 percent against six 8V and a third against eight 6V. On a four-seater that is roughly 24 miles against 28 against 36.

The trade is weight and money. Four 12V batteries weigh about 330 pounds against 380 for six 8V and nearly 500 for eight 6V, and a set of four costs a few hundred less than a set of six.

Flooded, AGM or lithium

Flooded is the default and the cheapest per amp-hour. It needs distilled water about once a month, the terminals need cleaning a couple of times a year, and it will sulfate if you leave it half charged. For a cart that is driven and charged most days, flooded is still the best value. The maintenance page covers the routine.

AGM costs about a third more, holds a little less, and asks nothing of you. It makes the most sense where the cart sits for weeks between uses, or where the owner is not going to lift the seat with a jug of water every month.

Lithium costs about twice a flooded set up front: about $2,400 to $3,000 for four Allied 12V batteries against about $1,200 to $1,560 for four T-1275s, and a little more than that against an Interstate set. In a four-slot cart it is a clean swap because Allied and a few others sell 12V lithium batteries in a car-battery case that drop in and wire in series like the old ones. The lithium guide covers what changes; the short version is 50 pounds less per battery, no water, and the same range from fewer amp-hours because you can use nearly all of them.

Reading the spec sheet

Amp-hours at the 20-hour rate is the number to compare; some sellers quote the 100-hour rate, which reads 10 to 15 percent higher for the same battery. Reserve capacity in minutes is a car battery figure and tells you little here.

Look for the date code stamped or stickered on the case or the post. A flooded battery loses charge on the shelf, and one that is more than six months old when you buy it has already lost some life. Trojan uses a letter for the month and a digit for the year.

Terminals on golf cart batteries are 5/16-inch stud posts or a combined post that takes a 5/16 bolt. The battery cables page has lug sizes and gauge if you are replacing cables at the same time, which you should if the old ones are green.

Which one for your cart

Cart	Stock layout	12V pick	Note
EZGO RXV 2008 and later	Four 12V	Trojan T-1275 or Interstate GC12	The tray is sized for GC12; group 31 AGM needs the hold-down shimmed
EZGO TXT48 2010 and later	Six 8V	Four T-1275 only as a budget swap	Loses about 12 percent range against the stock six 8V
Club Car Precedent, Onward, Tempo	Six 8V (some fleets four 12V)	T-1275 if the tray has four slots	Check for the four-battery tray before ordering
Club Car DS 1995 and later	Six 8V	Four 12V as a budget swap	Stock cables may be short for the four-battery layout
Yamaha Drive, Drive2, G19, G22	Eight 6V	Not recommended	Eight 6V gives far more capacity in the same tray; stay with 6V

Fitment pages for Club Car, EZGO and Yamaha have the serial plate locations if you need to confirm the year.

Install: about an hour

Photograph the old wiring before you touch anything. Set a Club Car or RXV to Tow before you disconnect. Remove the main negative first, then the main positive, then the jumpers. Lift each battery out with a strap; 82 pounds held by the posts is how posts break.

Clean the tray with baking soda and water, rinse, dry, and set the new batteries in the same orientation as the old. Wire in series: positive of battery one to the main positive cable, negative of one to positive of two, and so on, with the negative of battery four to the main negative. The 48 volt diagram page has this as a table by cart. Tighten the terminal bolts to about 8 foot-pounds, which is Trojan’s spec, coat them, and charge to full before the first drive.
