One thing ive found so far with these PRC-349 battery packs, is that its not easy to get crocodile clips to stay attached to the terminals! And with several dozens of them to charge and test, I need a better way to connect the charger.
What I need is a jig! Luckily, these batterys have a bolt that runs through the middle of them to secure them into the radio, si im thinking a piece of plywood, with a hole and a nut embedded for the securing bolt. A few bits of wooden moulding to form a frame, and something for the contacts. I do have a bag of 'upholstery nails' which will probably do for that. These are brass dome head nails, so hopefully a pair of those in the plywood, and then the charger connected to the pointy end!
I also still need to work out a sensible charging/discharging regime for these that will condition them within a sensible timeframe each, but also keep up a decent capacity.
