Hold good charge, very poor construction quality
on March 13, 2013
These are great rechargeables for holding a charge and powering your 9v devices. Great way to save money on 9v's each year when replacing smoke alarm batteries, etc. However the problem I've had is when I go to remove the batteries to recharge them. So far out of 6 batteries, I've had 2 which have the positive end just pop off. (it doesn't reattach). I'm currently in the process of getting them replaced with Tenergy, but do not use these for life saving devices, or if you do such as me with smoke alarms be very careful when you remove them from a device. We'll see how good the rest are when I go to remove them a year from now. :)
Tenergy customer support will not replace items ordered through amazon. So once past your 30 day return period your out of luck with these batteries. So be very careful when unplugging them when they come due for their first 6 month recharge, etc. Else you might as well plan on having some fall apart. I would have hoped Tenergy CS would have handled it better.
