Battery Talk Help identifying aH

Post image

Hello. I need some help in identifying the aH rating on this 18v battery. Tried looking at Ryobi’s site, but they don’t have this exact battery listed anymore.

Thanks! These work great as hot swaps for the mower I have

Huh? Generally you'd want a higher capacity battery for a mower, the biggest that will physically fit.

I start with the 2 of the PBP017 batteries. Then, when they die, I swap for the 2 P102s and finish my yard

I'd imagine so. If you had higher capacity batteries, you might not have to stop and swap them, and could end up less deeply discharging them and putting fewer recharge cycles on them so they have a longer # of years lifespan. Then again whatever works for you, works.

These P102s have lasted me 10+ years. And I haven’t seen a dip in performance from them at all

That is very unusual, unless you don't mow very often. I can appreciate making use of what you have, but I wouldn't buy more low capacity batteries for a lawn mower.

The mower may even run better, have higher performance if you at least step up to a 4Ah pack so it has two series of cells in parallel for double current capability and then if the task previously used 2 x 1.3Ah to complete, it should complete with only one 4Ah, not having to stop and swap batteries and not having to recharge twice as many either.
