Batteries for fishfinders

Hey guys,
I’ve got a few 12 volt batteries that could be used for fishfinders that my dad sent down to me. They test good and hold a charge, but I can’t tell you how long they will last because I don’t know how old they are. I’ve kept one as my spare and it seems to be performing as well as the one I bought from Batteries Plus. They are the size of a 12volt 7amp/hour. I don’t want anything for them, I’d just like to spread some goodwill if possible as I know these things usually run $30-$40. Probably not good for a color unit for a long time but plenty good for a greyscale or monochrome unit.
They don’t have a amp rating on them but they say 4.3 amp max; I guess for charging.
Let me know if you can use one. I’d take a donation to the HOW event coming up or maybe a good Flounder spot as trade.
Thanks, Rob
