"SteveB" toquerville@zionvistas fired this volley in
news
My grandkids have an electric atv. The battery is kaflooey, and I
need to get another. It is a 12v. 8ah, and says cautions on battery
acid. So, apparently, it is an acid battery. It is pretty much
sealed. It is approx. 2.5"w x 4"h x 6"l. I was wondering if I
could
just get a battery like is used in atvs or motorcycles or such and
use
that, giving it more riding time. These can be put in two at a time
if properly connected. Not sure + to - or + to +, but the
directions
will have that. Do you think that would be too much battery?

You can get 12v motorcycle batteries in the 20Ah range. They might
not fit exactly in the hole you have, but would be interchangable in
terms of voltage, and would last twice as long as what you have.

If you're using multiple batteries, and they're all 12V types, put
them in parallel. That is, put - to - and + to +.

DO NOT use flooded acid cells on a kid's toy.
NEVER.
AGM batteries for that application are common, readily available, and
relatively cheap. They are also leak-proof and safe.
