Re: Parallel Batteries
SLA batteries are commonly paralleled without any ill-effects in large industrial uninterruptable power supplies. Sometimes you'll see entire pallet-racks full of them. In these systems, I don't believe there are typically any diodes or switching. However, all the batteries start off new, and are all always charged and discharged together, for their entire lives, and aren't discharged often.
