    Charging rate for eneloops

    Why do so many people recommend charging eneloops at .5c or about 1000mah while the official eneloop chargers do it much lower at 200-300mah?

    Fenix lights with high CRI or 5000kl color temp

    Does anyone know if fenix makes any lights with high cri or a 5000k color temp?

    Noctigon Meteor M43 Disable blue led when light is off?

    Is there a way I can disable the blue LED on the power switch when the light is off? I don't want parasitic drain from this. Thanks!

    4 Samsung 30Q's down to 1v

    I bet it was parasitic drain then. It also had a breathing led effect on the switch which I couldn't disable. Unfortunately my xtar sp2 won't charge them at all, it just flashes red. I guess I will throw them out they are cheap enough.

    4 Samsung 30Q's down to 1v

    I've had 4 new n Astrolux MF01. It's been sitting for about 6 months, unused. When I went to use the light it wouldn't turn on, and when I went to charge the batteries it flashes red. Turns out they are each reading at only 1v in my multimeter. Can anyone tell me what the heck happened? Does...

    Fenix HL60r built in protection

    I am wondering if anyone knows whether or not the fenix HL60r has built in overdischarge protection, or must be used with a protected battery? I am also curious if there a list somewhere of neutral white fenix lights.

    Protected cells in (zebralights)

    If a flashlight has short circuit and over discharge protection, like all modern zebralights, and uses only one cell, there is no need for protected batteries, correct? In that case, would protected batteries give a shorter runtime or warmer operating temperature because of the Internal...

    Internal Resistance and Voltage drop among NIMH recharageable batteries.

    So even new high capacity NIMHs have higher IR? Or is it mainly because they have shorter lifetimes?

    Internal Resistance and Voltage drop among NIMH recharageable batteries.

    I'm wondering if these values are meant to be consistent among all NIMH rechargeable batteries. Or if, for example, it's normal for eneloop pro's or maha imedions to have different values than standard eneloops due to their higher capacity. I ask because I've noticed a trend among my eneloops...

    Eneloop Charge/Discharge rates for longest life

    What are the ideal charge/discharge rates on a standard eneloop during refresh and analyze on a maha C9000? I've read people recommend .5c to ensure the cells terminate. Would the maha not detect the endpoint on say a .35c charge? So about 700mah. The reason I ask is because the eneloop...

    At what capacity do you retire eneloops?

    That's an excellent thread, thank you. I will check the IRC on these cells. Do you still believe BIM should be adjusted to the battery's current capacity, rather than it's brand new capacity? I ask because I've been noticing decreases in my cells capacities as well after BIM, but have been doing...

    At what capacity do you retire eneloops?

    I'm wondering when you folks retire your eneloops. I've got a couple that after a break in on my maha charger are showing up at ~1750mAh and wondering if it's time to take them out of rotation.

    How much more efficient is a Cree XHP 70.2 or 50.2 vs a nichia 219c?

    Does anyone have numbers to describe how much more efficient the new cree lamps are vs a nichia 219c?

    Bright lights with the best efficiency?

    What are the most efficient lights to get for a long camping trip, where I want to make the lights last as long as possible but still want good brightness. Would it be any lights using Cree's XHP 70.2 emitters?
