Hi all,

I am lucky enough to have a mate that has lent me a Thumper 75ah battery for a trip that I am going on. He has no manual for it and I am unable to find one on the net. How do I know if the battery is charging, when attached to either 12v (Car) or 240v (transformer). I have pressed the button and it's showing me 12.00, does that mean what it has left or what it's charging at?

Any help would be appreciated.

I would assume 12 is the state of charge which is flat.

Why not ask your mate ?
He should know how it works shouldn't he ?

The voltage displayed is the current voltage level of the power pack. (What's left)

How do you know it is charging?
Your battery charger should tell you that.

After the charging process has been performed, this voltage should show something like 12.8 (full charge)

One word of caution.
Only use a multi-stage charger that ends in a float charge to avoid over charging the power pack. They are over $800 to replace.
If you use a dumb charger, keep your eye on the charging process and don't leave a charger connected that doesn't have float charge capability.

The best way of charging the Thumper is via the in-car charging kit, but of course you wouldn't have that.
