Otto The woods junkyard batteries are 40$ your choice,they have a shed full plus current take-outs on the bench. He just slapped the jumper pack on which tells you it's info. I've learned to slap the charger on...if it comes right up probably fine,if it's slow to come up to only an amp or 2 is probably sulfated,even walmart new ones !! You don't know how long it's been on the shelf and I don't trust those date stickers.
