I have a job were I have 7.2v 6 cell ni cad backup batteries.
These look similar to the battery packs that are used in rc kit.
I need some way to test how good they are before I refurb the kit and re issue it to the clients.
If the mains power is cut it is very important that the
backup is good enough.
I hope there is some cheap way of concerning the battery is good.
As we know there can be good voltage and no amps.
