Deruicent 4 Pack 3.7V 18650 Rechargeable Li-ion Battery for High-Power LED Flashlights, Headlamps with USB Dual Battery Charger for Li-ion 18650 14500 16340

Great quality batteries. Bought these for a flashlight I use regularly. I also like that it's micro-usb charged. I have a portable battery bank that i carry that can charge my phone or flash lights. Definitely worth the price & would buy again in a heartbeat.

I use these in my Niwalker 4 cell flashlight. Seems to work better than my Olights. Excellent value for the price.

. need to have them at least a year. have no clue as to whether good or bad

I was able to charge two batteries and when I placed the other batteries in and went to plug the charger cable into the base unit, the interior plug broke off inside. Extremely poor quality.

Easy to use! Charged all the batteries so they’re ready for my husband’s present that requires them.

Batteries were recomend for my flashlight I purchased after charging they do not last as long as they should even on low

Fairly quick charge, very useful in high output flashlight.

My husband ordered this specifically and loves it.
