Re: 1502 TDR Battery problems

Greg Muir

If you don’t plan on using a battery in the future or simply need to get the unit working on 115V there was sometime in the past a power supply mod where you pulled a transistor off the board and the unit would not recognize a missing battery. But the caveat here is that the mod inhibited the battery over/undercharge circuit so care had to be used by replacing the transistor if a battery was again going to be used.

As for the quality of replacement batteries, I have been using the tabbed Tenergy brand C cells with no problems. Good charge life, charge well and have had packs for years without any failures. The tabs allow you to rebuild the pack with ease.
