Universal Remote Control Li Ion Rechargeable Battery

[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!

[15.6 lb] li-ion is the way to go.

[0.155 lb] Rechargeable lithium-ion battery used for Olympus camera works well everytime.

[0.25 lb] I have several of these that I use as holders for small Li-Ion battery packs on Astronomy equipment. They are well made and hold the equipment securely.

[1.5 lb] The Panasonic DMW-BLG10 Li-Ion Battery and Charger Travel Bundle came quickly. I like having a second battery charging while still using my camera.

[Lithium-Ion] This battery is an updated version of the 5400mAh. All of the previous versions of Li-ion lasted (my are over 10 years old,) but you never knew how much power was left. This version has LED to let you know. Nice.

[0.165 lb] Solid, reliable replacement Li-ion battery for my Panasonic cameras that require the DMW-BLC12 battery. Brilliant, Watson!

[~2 seconds] I have the larger version of this battery tester but also wanted to be able to test NIMH and Li-Ion 9v batteries. I am very happy with both testers and feel like these are the best on the market. Highly recommended!

[11.1 VDC] I use this battery as a back-up to my Nikon battery EN-EL4a rechargeable Lithium-ion Battery Pack. I always use my original Nikon battery but if I am out in the field and my Nikon battery goes down after many shots, I then switch to the the Watson EN-EL4A Lithium-Ion Battery Pack as my back-up until I can re-charge the Nikon battery again at home. I find it's more economical using it that way since there is such a big price difference between the Nikon Battery and the Watson Battery. However the Watson battery is a very good battery and reliable in every way.
