Lithium/Rechargable mAh ratings and Flashlight use

[Aux]

I noticed on batterystation.com that lithium and rechagable cells come in different mAh ratings. Is this a consideration in flashights?

Will higher ratings produce more light, or damage incandescent or LED bulbs?

I am interested in using these in attempt to avoid some of the leaking issues I have had during our long hot summers here (see my previous thread "Leak Safe Batts?").

mAH = Capacity

The more mAH, the longer your flashlight will burn:)

This has nothing to do with the battery voltage: A higher voltage will give you a brighter light and could damage the bulb or LEDs...:(

BTW: standard rechargeable cells (AAA,AA,C,D) are always arround 1,35V-1,45V (fresh from the charger).

So I will get less output from the light when using rechargables, correct?

If it's an incandescent, yes. If it's a regulated LED, no.

Thís is not always the case...if you´re going to draw large currents, the rechargeables will be brighter. Alkalines have a high internal resistance (high currents=big voltage drop!), rechargeables have a VERY low internal resistance /ubbthreads/images/graemlins/grin.gif

If you are storing the light, use lithiums. If you are using the light, use rechargeables. The rechargeables will also give you a more steady voltage versus the alkalines that will slowly turn more and more yellow-but won't stop until you can't take it anymore. NiCD will give you a steady 1.25 and then within 30 seconds, just fade.
