Scrubber batteries are designed for scrubbers and must compromise in some areas.
They will last roughly 70% of the cycles versus a T-105
They are built to pay homage to reserve capacity duty and not CCA nor the 20 amp hour rate. Medium rate discharge for a couple of hours. These batteries bow and pay homage to Peukert design concept. Narrow performance range because they have to be sized to squeeze into a scrubber.
They are acid starved. They sit on a charger after supermarket floors are scrubbed. from, say 4:00 AM to the following midnight so charging agility is not important.
