Rechargeable Lithium Polymer Battery 3.7 V 1800Mah

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

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.

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.

The Sony NP-FZ100 Rechargeable Lithium-Ion Battery (2280mAh) delivers as promised as an OEM battery.

Coast’s lithium battery ZX450 all batteries that Coast supply are excellent. Reason I say this is because rechargeable lithium batteries sometimes have issues like premature failure. Things like not taking a charge, memory issues, and short run times to name a few. I do handle lion cells as recommended which is important for long life. Coast batteries and my lithium cellular batteries are the only batteries that work as promised regarding rechargeable lithium cells. I expect an a dramatic improvement with rechargeable lithium batteries of all sizes any time.

Best speedlight ever made!!! Namely due to the rechargeable Lithium battery that holds a charge through hundreds of uses.

The Sony NP-FZ100 Rechargeable Lithium-Ion Battery (2280mAh) is reliable, just as you would expect from an OEM product.

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.
