Hello everyone, I bought 4 pieces of LGHE2 18650 High Drain 2500 mAh batteries and a Nitecore D2 charger. Can anyone tell me how long does it take to fully charge a pair of this brand new batteries with the charger please? I know this charger will automatically stop charging when the battery is full but I still don't wanna leave these batteries with the charger for too long when they're full. Any advice would be nice. Thanks.
