[0.03 lb] Eartec Rechargeable 3.7V Lithium-Ion Battery for UltraLITE & HUB Systems

[3.7 V] Nitecore 18650 Li-Ion Rechargeable Battery is a great source of stored energy. Being rechargeable makes this battery cost effective. This Nitecore Li-Ion battery has demonstrated its dependability in a flashlight over a period of seven hours of intermittent use. Great product!

Eartec Rechargeable 3.7V Lithium-Ion Battery for UltraLITE & HUB Systems

[7 x 4.55 x 2.6"] I have a Streamlight Polytac flashlight that only accepts 3v cr123 batteries. all other rechargeable cr123 batteries are 3.7v which is too much voltage, but these Watson batteries work great. I love how these Watson batteries came completely sealed. B&H photo seems like the only place that carries them. I hope they don't ever stop!

[0.1 lb] 18650-type lithium rechargeable batteries are very popular for high-powered LED flashlights. These batteries have a high energy content (up to 13 watt-hours) and are capable of high peak current discharge (up to 40 amps); they should not be stored loosely such that an accidental short-circuit could occur! This carrier is made of very tough, flexible rubber, about 2 mm thick. It securely holds the batteries and protects the battery contacts. Unlike a tray-type carrier, this carrier allows single cells to be removed or inserted without allowing the other cells to become loose. You can carry extra batteries in your toolkit or range bag without fear.

[3.5 oz / 100 g] These new V.3 pouches are even better than the V.2. The rain covers are designed much better!

[0.065 lb] These are a perfect replacement for Ring solar lights that use protected 18650 cells as Ring does not sell their own branded 18650's separately. I charged them up on my Nitecore charger with the rest of my flashlight batteries to ensure they were fully charged and they've been working perfectly in my solar Ring lights since.

[0.81 lb] Excellent charger. So far I have used it for 18650 batteries in protected and unprotected versions, 18350, 16650, and 14500. I have also used it with NiMH chemistries. It can pretty much charge anything I throw at it.

[0.185 lb] Great light but getting the rechargeable battery will make you use it so much more often.
