PowerFLARM portable: rechargeable battery recommendations

We have run various tests with high temperatures rechargeable
batteries and PowerFLARM.
I will spare you from the details, but the conclusions a

1)
Recharging must take place in an area where the ambient temperature
does not surpass 95 degrees Fahrenheit (35C) as otherwise the PF
charging circuit will refuse to charge to prevent overheating.

2) Best rechargeable batteries to use (by far !) a
Sanyo XX Battery Powered by eneloop, 2500mAh High Capacity, Ni-MH
http://tinyurl.com/PF-rechargeables

Make sure they are the XX 2500mAh type, Sanyo/eneloop also sells lower
capacity AA's

With these batteries we have repeatedly measured runtimes of over 9h
at 70C (158 F) ambient with full backlight.

We will update the manual accordingly.
Please also remember that PowerFLARM does not charge the batteries
when it is turned on.


See you all soon!
