Is it possible to overcharge or "burn out" a battery? I keep 1 on the charger while I use one, but they seem to loose thier spunk after just a couple of hours so I am constantly changing them out every 2-3 hours.
If a battery is functioning properly it can be charged 300 to 500 full charges before it starts losing power. Normally after that time it will only charge to about 80% of the normal full charge.
You can charge them as often as you like. When the battery is down to 50% and you charge it that would only count as a 50% charge, not a full charge. When you charge it twice at 50% that would count as a full charge.
Right now you just started and I suspect you are chain
vaping. I did too, but it will taper off.
And welcome Sean.
