I've got a Quantum Battery 1+ that I think the battery is dead or
discharged in storage until the battery is unrecoverable.
It won't turn on, but the charging light & all the power leds light up
when the charger is plugged in.
It takes a 6v 2.5ah sealed lead acid battery unit that looks like three
D-cells soldered together and shrink wrapped.

Batteries Plus here in Raleigh can get the individual cells, connect
them up and shrink wrap them to make a replacement. Probably cost around
$30.00 ... replacement power pack is going to be at least $150 if I can
even find one used. I don't think they make these any more.
But I was wondering ...
Is there any reason I can't replace that battery with a larger capacity
Gel Cell if I can find one that will fit inside the case? If a 6v 4ah
battery will fit in the case, could I safely use that in place of the
the 6v 2.5ah battery.
No warranty issues, these are OLD power packs. But I'd prefer not to
burn up the circuitry.
My understanding is that "dry" (ie gel, glass mat and all the other
sorts) lead-acid cells require greater currents for charging than the
plain vanilla version. You may want to do some serious research before
taking the plunge. FWIW it seems likely that the cells would not charge
if the circuitry was inadequate, rather than some damage being done to
the electronics.
