Battery Charging

[Krimble]

I am currently using a Nitecore I2 charger to charge two Sony VTC4's that I use in my sigelei 150w. I bought both batteries when I purchased the Sigelei and only used then in that mod. It's never done this before, but while charging, one of them took an extra hour or so to completely charge. The only thing I have done differently from before, is build a .18ohm dual coil setup running at 100-120 watts, higher than the 20-60 watts range I was vaping at with previous higher resistance builds. Is this normal? I just found it weird since it has never done this.

Sometimes mine take a little longer than the other. I have my batteries numbered and I reverse the slots they go in each time they go in my Sigelei 100 Plus. Others may differ in their opinions. Keep an eye on the voltage when you first charge them and it should be very close to the same. If they go down to roughly the same voltage I can not see a problem.

Every once and a while, my notecore won't make solid contact with a battery and it will take longer... When I notice this, a quick wiggle to seat the battery better fixes it. If it happens once, nothing to worry about...swapping batteries in the mod slots is a good idea, this will ensure even wear on the batteries if one slot happens to have a bigger draw then the other.
Sent with one hand, the other is busy vaping.

I have 3 Sig 100Ws. I also swap their positions in the mod and charger. One battery is always slightly more discharged than the other, but an hour extra in the charger seems like a lot.

I would like you to check the voltage on the batteries before charging with a DMM and see if there's a large difference. And check them after charging as well. If they are both close to 4.2v afterward, I wouldn't worry too much. However, if you're seeing one battery with a lot more drain before or after charging, it could be degrading faster, and it may be time for new batteries.
