Rechargeables advice?

[alexcollinge]

Hello all,

I'm currently checking out rechargeable batteries and chargers (specifically 9V pp3 batteries) for use in a set of radio mics, which seem to be generally regarded as a relatively high drain appliance.

I went straight out and bought a bunch of 9.6V 220mAh PP3's from a manufacturer I admit I'd never heard of (Vapex). The batteries were mostly duds and the charger I found wasn't much better - finding chargers from recognised manufacturers that catered for 9.6V PP3's as well 8.4V ones turned out to be damn near impossible.

The duracell and energizer rechargeables on offer only have 170/175mAH and not having an intimate knowledge of how these things work I was wondering if anyone out there could tell me whether such specifications are good enough for my desired use. I don't really want to carry on forking out for standard batteries. Also the chargers on offer never seem to offer a charge status function when charging PP3 batteries.

Sorry for the long post!

Thanks,
Alex

You didn't tell us how many mA your load requires at what preferred voltage, and how much operating time you expect to get out of a charge.
