Query: Bad BRAND/MANUF. for 9V or any MiMH cells

Bought 3 of these Maha/Powerx 9.6V batteries in 2007. I also bought the Powerx 9V charger to make sure the batts. were properly charged. One of the batt's negative (-) terminal broke off a week after purchase, so it had to be solder on. All three batts. failed within one year: the charger would fault out for bad battery. Using a Lenmar charger, I was able to trickle charge them, but they drained very quickly in actual use.Similar -- but not as bad -- experience with Powerx/Maha AAA and AA.Select another BRAND.
