Multiple chargers, individual batteries.

I got my precident out of storage today, and it won’t take a charge. (6, 8 volt batteries. I disconnected all the cables, and measured each battery. Has 3 within 3-4 volts and the other 3 were under 2. I put each cell on a charger, 3 charged individually to above 8 volts , but the other 3 stayed under 5 volts, on all of them, voltage dropped again, within 15 minutes of removing the charger cables. Can I hook up multiple chargers to try to get them juiced enough to get the charger to recognize the set of 6. These are only 2 year old batteries, and I don’t want to have to replace them again, '

Yes. Use the 12v charger on the lowest ines to bring the total pack charge up as much as you can and quickly plug in the oem charger. I think (but not sure) it needs to see around 40+ volts to turn on

You won’t hurt anything by hooking an 8v battery to a 12v charger for a bit. Usually 15 minutes per battery is enough. And make sure they all have enough water.

If by luck, you have another 48v cart around, just jump them. 1st - Connect both carts with jumper cables across the full battery pack. 2nd - While jumpers are connected, plug the cart charger in. 3rd - Remove jumper cables after the cart charger activates. All the best.

I've done this in the past. Used my 12 volt charger to bring out of a comma, and then used cart charger to get them up to snuff.
