Charging batteries overnight

[Ryedan]

The issue with lithium ion bats is that once they are charged full, at around 4.3 v, any more energy put into them will turn into heat. If this is allowed to continue they will start burning. If the case they are in is not designed to vent the fumes produced, they will explode.

So, if the charger does not stop charging, there will be a problem. I never leave any lion battery on charge overnight. It might be a 1 in a million chance, but why would I take it if I don't have to

Don't wait for your battery to die to charge them. They'll last longer if you don't and won't have to charge as long.

Not true. batteries last longer if you let them die then fully charge after, Just like a phone battery, they have a memory of a sort as far as charge cycles.

That was the case with NiCd and NiMH but isn't the case with Li-ion cells.

1. Never take anything at face value.
2. There is more wrong information on the internet than there is correct information.
3. It is impossible to eliminate all risk. Especially when the probability is somewhere between lightning and lottery.
4. It's too late in the day to begin correcting the wrongs in this thread.

Charge at your convinience, don't be a slave to batteries.

I must agree with you.

However, each of the YL-103A chargers shown in my posts charges at only 300mv to 350 mv and requires 6.5 hours to charge a 1050 mAh battery discharged to less than 3.7V.

This is a perfectly good charge regimen for my semi-regualted 3.7V APV.

And, I still don't leave my batteries charging over night. I have a couple of a twist, an eGo C and eRoll that I rotate throughout the day.

4.2 V is maximum recommended charge for 3.7 V li-ion batteries of any type. If your charger exceeds this voltage amount it is defective. Somewhere between 4.10 and 4.19 v DC is best for freshly charged Li-ion batteries of all types.

My cheapie YL-103 chargers will discontinue any charging when a maximum of 4.13 to 4.19 is achieved. Then it shuts off. How about your charger?
