Common Questions
What is the current temperature of the battery?
When attempting to create a "9V" battery, you have to settle for either 8.4V or 1.2V because NiCad and NiMh cells are only 1.2V each.
How long does it take to charge the batteries with the included charger?
I think the batteries are smaller inside the package, and I used the charge/discharge/freeze repeat sequence for a few months for a couple of months, and now they work great.
Will this charger over charge the batteries or will it stop charging?
It will not over charge the batteries, but it will stop charging after it tops off.
What is the difference between the 9v premium and the 9v low self discharge battery?
I purchased this for the same reason.
Is it possible for this charger to charge li-ion 9v rechargeable batteries?
The 200mAh is the amount of time a battery will last.
