Love the on-board charging port
"These work well. Being able to charge with just a cable, combined with having a LED charging light is great!"



This little battery just got an upgrade! The Fenix ARB-L16-700UP USB rechargeable Li-ion battery can be charged by its own USB port and by the charger as well! The new protection circuit located in the anode protects against overcharge, over-discharge, short circuits and overheating. This new model is also fully covered with a steel shell that greatly reduces the risk of short-circuiting caused by collision or impact. With the upgraded, higher discharge rate of 3.5C than the previous models, you can be sure your favorite devices and lights last longer with the big punch this tiny battery provides!

"These work well. Being able to charge with just a cable, combined with having a LED charging light is great!"
"They work well, and charge quickly"
"I ordered this lil guy as a backup for my work headlamp. It fits in the Fenix apb-20 storage headlamp case along with the light and charging cable perfectly."
"These batteries are easy to charge, work well in equipment and seem to last a long time. Plenty of power for my needs."
"I use this Fenix battery in any of my flashlights that can take this size battery. 700 mAh is 50 mAh more than most RCR batteries, which are usually 650 mAh, and it can make a difference when you really need it. I like having the option of plugging the battery into a USB charger or putting it into an external charger. The battery has a red indicator light at the top that changes color when the battery is charged. The battery measures 34. 9mm long, which is a little on the long side and may not fit all devices. I am satisfied with the purchase."
