Default Re: NiCad Battery - Internal Component ID

Do your battery packs have an Amp-Hour rating on them?

If so, create a test load which will draw approximately that amount of current from 1.2V and connect the test load across each cell in turn. If the cell voltage holds up while it is supplying that sort of load then the batteries are good, but if the cell voltage collapses, they are not good.

If you think your problem is actually tarnished or corroded external pack contacts, prove it - bypass them by making connections directly from the cell pack's +ve and -ve to the power terminals of the unit which is normally powered by these.

If that doesn't work then you know your problem is elsewhere.
