Sometimes I even forget the I have to charge this battery. It's an Info-Lithium Battery with 6600mAh at 7.2V and it have a very long life!

If you’re looking for a replacement for your Ring Solar Pathway Light button type, 18650 3.7V battery, this it.

These new V.3 pouches are even better than the V.2. The rain covers are designed much better!

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!

I had no complaints with v.1 but I can notice a (very small) improvement in the finish of v.2. It’s now less rugged which makes the image a little less “blurry”

Rechargeable lithium-ion battery used for Olympus camera works well everytime.

The Nikon EN-EL 18d Rechargeable Lithium-Ion Battery is a super battery with an incredibly long life and easy to recharge. Highly recommend!

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.

These batteries can be used for different pieces of equipment that take the NP-F 6600mAh lithium-ion batteries and the charger it comes with is extremely compact and works great.
