FAQ:

Q: What is the best 18650 unprotected battery and Charger?

A: Re: what is the best 18650 unprotected battery and charger ? Right now, the Panasonic protected NCR18650B 3400 Li-Co cells are at the top, same for the unprotected ones. Some labels using protection are longer and some are shorter, so you’d need to be mindful of that and what length your light can accommodate.

Q: What’s the safe charge voltage for 18650?

A: 18650 lithium-ion batteries are charged up to 4.2V and down to between 2V and 3V depending on the cell’s specification for cut-off voltage. To be safe, never discharge lower than 3.0V unless you know your cell’s specification. Discharging occurs anytime you use the battery for power.

Q: What is the best way to charge 18650 batteries?

A: The 18650 battery charging method is divided into two steps: first constant current and then constant voltage. The first step is constant current charging until the voltage rises to 4.2V. The second step is to switch to constant voltage charging after the voltage reaches the charger setting value.

Q: How long do 18650 batteries take to charge?

A: It generally takes about 4 hours to charge an 18650 mod battery using a separate charger. If you use a Micro USB charger, it is likely to take about three hours. However, be advised that there can be some slight variance in charging times, even for a new battery.
