Performance Tool W2974 multimeter
Eagletac 18650 battery 4.2-4.25v OCP, 2.7-2.9V ODP, Short Protection 3A-5A
Ultrafire WF-139 charger
We have been going by when it starts to dim, its time to charge. So far been effective. It barely started to dim so we decided to charge it. Had not been charged in a couple weeks, and had a power outage today do figured it would be a wise decision. Take out the battery, get out the meter and realize the meter had has been left in the on position at 20 DCV. The battery symbol is on indicating needing a battery change. Crud. Its one I am not supposed to change the battery on from Advance Auto. But, its still on after being on for a couple weeks so maybe its ok. Measure the battery, 4.85 volts.
Normally when we measure it before charging at this point it measures 3.7 ish. After charging, 4.2. So, after setting the battery in a safe place, decided to let it and the meter set. Hour later went back to check the voltage, now 4.49. (just now). So, is the battery 
or the meter or both .
Battery nor flashlight showed any indication of a problem. Still don't.
