Since CR123A re-chargeable Li-jon batteries is hideously hard to find in Sweden, and since one battery of the same model, cost about 3 euros a piece, I decided to order myself some rechargeable batteries.
I will use them for flash lights. (ESP- or \"Euro security products\" a very nice company that produces high quality security products (obviously). My \"Barracuda\" with CREE-chip 3W LED) is an amazing torch but that really costs to use, 2*CR123A or locally: 6 euros per hour (expensive batteries over here!). Manufacturer ESP claims light output to approx 3500 lumens at a distance of 1 meter. This bad ass torch is a power consumer and with 6v 2*1300mAh non-rechargeable batteries, approx 30-60 min of maximum light output, then the light fades fast.
Info: The re-chargeable 900mAh batteries came pre-charged (thank you!). And I\'m currently charging my first charge now. 0,99 cent for a tiny European AC-plug, very affordable. Came well packed, and I\'ve even got a free keyring flashlight (small diode) ^^)
Having played with the Barracuda for testing-purposes, it seems to act a bit weird compared to ordinary 1300mAh non-chargeable batteries. From maximum light output to no light came VERY unexpectedly. There were no fading light, just from high output to nothing in a second.
Actually I like that, have always got annoyed with fading light, rather know when the batteries is at an end, than throwing away batteries with power left in them. So the combo of 2*3V 900mAh re-chargeable seems to give what I want.
The batteries seems to last 60-100mins with continuous light, but no one want to hold the torch for that time since it gets VERY hot (you will burn yourself). Considering the high output CREE LED diode, ~60mins is great.
I have not scrutinized this, but with 2*1300mAh with the fading strength of light, I\'m sure I get the same or even longer maximum light output with the re-chargeable 900mAh, which is interesting to say the least.
Good prices, good batteries, good quality so far. If you need CR123A, 4 batteries, charger and euro-powerplug for 30 USD + shipping, its worth it..
