We have recently purchased a nice reasonable sized battery pack with built in charger. The 12 pound "Mity Mite" is designed for jump starting a car but looks like it can be really useful for timing applications. The unit has a cigerette lighter socket and battery clamps to attach to a car battery. It has a built in charger that connects to any extension cord. It is the model PS-120A made by Schumacher Electric Corporation. 800-621-5485

I have the same battery pack BUT....I misplaced the 110V charger. Can you tell me the specs off of yours so I can find a replacement? Output voltage / amps off the wall charger.

Our Mitey Mite has the charger built in. Otherwise use any good charger made for lead acid "gel cell" batteries.

The Power Sonic PSC 12250-A is a decent small charger. 300 MA with initial voltage of 14.9 VDC tapering to 13.8 when completed.
