Review on Tenergy 9V NiMH Rechargeable Batteries, 200mAh Long-Lasting Square Battery for Smoke Alarm/Detector (2 Pack) by Tanya Reed

I bought it for a multimeter and it works fine. AAA elements and now 9V. Of the 8 D cells, one failed to charge and (The Battery Superstore) was promptly replaced. I just sent in a bad battery and received another two days after sending it back. I bought everything else afterwards. I use 32 AA for RC trucks and controllers. That saves a lot in the long run. I've charged AA cells a dozen times or more and they actually last longer the more you use them, like 0.25 ton or more. They were new from 1.355 to 1.36, some are now 3.95 volts. I check them every time I charge them. I used the C elements for the cordless drill/driver battery. There were 14 18 volt nickel cadmium batteries in the original packaging, I used 15 batteries for the new one. I sealed it with black tape so it doesn't look good but will bury the 3" screws for a while. This is a brand new drill. I soldered AAA batteries in 5 packs to replace 4 AA batteries on board RC trucks.
