In Reply to: Replacing sealed lead-acid batts with Li-ion, or?. posted by Coner on November 2, 2009 at 18:46:02:
AFAIK Gates are a variation on sealed lead-acid (SLA), so those are usually charged from a supply that combines current-limiting and voltage regulation. Current limit is something like C/5 (where C is ampere-hour rating), and the final float voltage is around 2.3 to 2.4 volts per cell. Cells with a different chemistry will require a very different charger.
A local electrical/electronic supplier (the kind of place that's located in an industrial park and sells a little of everything) should have a selection of SLA batteries. If they don't stock 4V or 8V batteries, they'll have catalogs and may be able to bring some in cheaper than you can. Googling 4V SLA turned up some made by Power-Sonic, like the PS-445. Capacity is similar (4.5 AH), and it might even fit in the compartment.
