Buying for a flashlight?,
This review is from: Kits: 4 Tenergy RCR123A 3.0V 900mAh Rechargeable Li-Ion Protected Batteries with a Smart Charger (Accessory)
These batteries appear to be great at first. They work just according to instruction, rechargeble batteries that you can be used over and over. It will save you a lot of money. So far all good.
The problem was I never got close to the runtime that I was suppose to when I used them for my FenixP3D CE Premium Q5. Estimated runtime according to the manual is 4h50min for the 120-lumens mode. With the Tenergy (900mAh) batteries I get about 1h 45 min, which is actually the best of all the 3.0V rechargeble batteries I have tested. Tenergy 750mAh gives 1h30 min, while a non rechargeble battery provide more than 5 hours of lighting!
If you are buying for a flashlight and it has a regulated voltage circuit, like my Fenix, you can buy 3.7 volt 1300mAh rechargeble batteries on for example ebay and get much longer runtime. The ones I have tested gave me 2h 30 min runtime, which is half the strength of a non-rechargeble battery, which I think is accepteble.
