Golf car batteries get blast charged 2 to 3x a day, go back on the charger as soon as the golf cart acts sluggish, and then someone drives it back and grabs a fresher charged cart. Then end of the day, into the shed for a full overnight charge session.
Sweeper battery aka the T-1275, runs all night, sweeping floors at stores while everyone else sleeps, until run down. Then back to the shop for a full 14-16 hour recharge session to be ready again for the next nights work. Some golf carts run on T-1275's but in my opinion, it's not in the same league speed charging wise, as a T-105. A T-105's design screams "abuse me" on the charging cycle, it has a lot of battery acid in it, it's not confined to dimensions of height, as it sits easily with plenty of space under the seat, so the height dimension of the design is not a recharging constraint. Not so with the T-1275... it's stuffed into a compact tiny floor sweeper, it's dimensions are a design constraint, so I assume you need to recharge it accordingly, slowly. Good candidate for solar recharging all day on sunny days, to get it fully top charged, but in my observation, it takes it's sweet mary anne time to get those last few percentage points to truly get it top charged. Not getting it top charged daily is where the cumulative damage starts on a T-1275. It gets stubborn fast if it doesn't get those last few points daily. IMHO.... of course. But I'll defer to mexicowanderers input... my battery had been pretty worked before I received it.
