The Battery sold as being a direct replacement for the jump-n-carry 770R is NOT. The placements on the connection points are off by 1/4-1/2” inwards! I had to rework the buss bar(?), that connects the battery to the rest of circuitry. Size was OK fit inside all right amp hours the right amount, but the placement for the battery connections is off. It does not work. You should either reconfigure the battery or stop selling it as a direct replacement. It is not what it is is a very good inexpensive option but you have to be able to get your hands dirty so to speak and reconfigure grind cut, fabricate, etc. to make it work. I’m cheap enough to do that and didn’t wanna pay the price of the Clore Battery for one that supposedly was a direct fit was almost the same cost as buying a new one kind of a joke. The whole thing I won’t be buying these again the Clore Battery jump/carry thing I’ll go with a high capacity discharge unit.
