Right lads as a few people have been asking about these here is 2 test which might be useful to a few members asking about them.
Batterie Test was done by roybert
TEST 1
Runtime test on the Powerex NiMH 2700 batteries.
These were brand new and have had only one 2 hour soft charge in my Powerex MH-C801D charger.
I placed 4 of these in my Priceton-tec apex last night at 23.59pm and swiched it on to the high 3 watt mode.
Low Battery Power Flash Started at 4.34am, which is indicated by 3 short flashes and again followed by another 3 which usually means that the lamp has a further 20 minutes of runtime remaining at that power setting, or you can switch it down to a lower setting to increase the burn time.
so that was 4 hours and 35 minutes on full power.
I had to switch it off and go to sleep at 5am because my eyes were doing the conga, it was still running on high 3 watt mode and producing a good brightness and spread of light. Got up this morning put the lamp back on full power and it's still going Very Happy
This is a seriously good headlamp and the performance of these batteries coupled with the charger I have are Amazing.
TEST 2
Update on another battery test, same batteries POWEREX 2700
now been charged and discharged 4 times.
Charged them on my MAHA MH-C801D ON THE 2 HOUR SOFT CHARGE MODE.
Set the light away at 6pm last night on the 3watt Maxbright High setting and it flashed 3 times followed by another 3 at 11.30pm, 5.½ hours on full power, when it blinks 3 times twice in succession this means you have a further 20 minutes at this power or you can switch down to a lesser light mode and still have light. NiMH batteries are not able to to accept or charge fully until they have been charged and discharged at least 4 or 5 times, It is not recommended running the batteries all the way down or until the lights go out. This could result in over discharge and permanent damage. Once you feel that the lights are dimming, you should recharge them right away.
You should run the conditioning cycle on your charger “if you have that facility” once every ten charges. This will help extend the overall life of the batteries.
Rechargeable batteries
Rechargeable batteries include NiCad NiMH and Lithium ion
All 3 of these types of batteries are capable of delivering high currents and can dump their power very rapidly.
They don’t like to hold a charge when not used for a long period of time they leak their power and they loose some of their charge on a daily basis, Lithium ion are least affected by this characteristic.
All of these batteries should not be overcharged (DON‘T COMPLEATELY EMPTY THEM) or then can be DAMAGED and won’t hold a charge well anymore.
Generally a slower charge rate is better for making them last longer.
