Trojan built those T1275's for the golf cart market that wanted a cheaper way to power the typical 36v golf cart. They are built similar to the T105 but smaller cells. They ended up to be a disaster for the golf cart market. The majority of the golf cart sales are to golf courses and the 3-T1275's would not make a full day of cart rental if they were busy and their course was hilly. They are good batteries just not enough capacity for that application. Golf course management was not happy having to tow carts in with unhappy golfers(-:
I'm using 6-6v Full River AGM's for house batteries and so far I like them.
