3.7 V 1200Mah Lithium Polymer Battery

Purchased the DMW-BLC12 Rechargeable Lithium-ion Battery (7.2V, 1200mAh) as a backup for my Leica Q. Works flawlessly and entirely likely that the two are identical except for the branding printed on item (the two companies have a close relationship with one another). Lasts equally as long as its Leica-branded counterpart, fits perfectly in the Leica charging unit and seems to have no downsides. And for the price compared to Leica's own model, it's a no-brainer.

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

With the current restrictions on shipping lithium polymer batteries, AC adapters are sorely needed for studio assignments that have larger numbers of photos that need to be people.

This lithium battery is very reliable.

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

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”

The card fits perfectly in my wallet and is a tough polymer with some flex, not likely to crack. The battery feature on the key fob is an excellent upgrade also.

This little flashlight packs a punch. The secret is in the 3.7 volt/ 2.4Wh 16340 with built in USB micro rechargeable port (on the battery). That battery gives this little flashlight a powerful long lasting bright beam. I'm glad that I purchased two of them. I keep one in my toolbox and the other in my car. Highly recommended.

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

I bought this because I purchased a flashlight that will operate on either a AA battery (1.5 volts) or a 14500 battery (3.7 volts) and this battery works very well in this application. It fit in the flashlight just fine and it holds a good charge for a long time. I have only charged it up 2 times since I got it but I am very pleased and I will by again.
