Are you wondering about 12 volt batteries, then, why they weren't mentioned in this discussion? It's because the "Lead Foot Factor" I just mentioned becomes a REAL issue with 12 volt batteries. These are usually reserved for either AC drive systems, which use batteries more conservatively, or EV racers who are simply looking to pour as many amps into their electric motors for the quarter-mile as quickly as possible. They don't care if the range is stunted by the drivers lead foot, just as long as they win; ) Most popular 8 volt golf cart batteries used in electric carsTwo major brands of 8 volt golf cart battery dominate with respect to EV popularity: Trojan, with their most popular T-875, the leader by far, and their T-860 (less AH) and T-890 (more AH); and US Battery with their 8VGC family. Trojan T-875 8 volt golf cart battery These don't come in the preferred L-terminal type, so be aware of this before you decide on an 8-volt battery format.
The Trojan website isn't too forthcoming with cycle life information for these (I got "650 cycles" from a discussion on the EVDL), nor rate of discharge at 75 amps (which is the rate that matters more to EV drivers). Trojan T-860 8 volt golf cart battery

The US Battery 8VGC comes in three flavors, depending on the number of amp hours you want. More amp hours means more lead, so the higher the AH, the heavier and more expensive they are. US Battery 8VGCE-XC

Expert Opinion: Northwest Golf CartsI called up the owner of Northwest Golf Carts, Inc. here in Seattle this morning to ask him a few questions about the different 8 volt golf cart batteries available for sale. He says that, in his 18 years of experience in the business, he's found the Trojan 8 volt and the US Battery 8 volt batteries to last pretty much an identical length of time (cycle life) if you take care of them properly. He emphasized the point about taking care of them properly. This means keeping the water and the charge topped up! Remember, lead-acid is too stupid to have a memory, so you DON'T have to let them drain every once in a while, and it's not recommended. The Trojans cost a lot because of their name, but USB's are just as good and cost a little less. He said that Trojan doesn't honor their warranty as religiously as US Battery, and this is a good enough reason to get the US Batteries instead. US Battery is great with their battery warranty. Warning!Exide batteries are cheaper than the Trojans and US Battery 8 volt golf cart batteries, so a lot of folks are tempted to buy them to save money; but in the NW Golf Carts, Inc. owner's opinion, it's a waste of money. You get what you pay for. He says that Sears, Les Schwab, and Napa all market Exide batteries under their own brand, but they are just as...cheap, shall we say? as the ones with the Exide label. What about Interstates, I asked. He said, "Those ARE US Batteries. Go ahead." Many thanks for the info! You can find Northwest Golf Carts, Inc. at:
