Black Diamond AAA Rechargeable Battery (4 Pack)

The other poster complaining about the head lamp not able to charge these batts must be suffering from user error. I purchased 2 EXTRA packs of these black diamond rechargeable AAA batteries so I can have extra charged batts ready to go for my Black Diamond ReVolt 110 Lumens head lamp. Coincidentally I also use these AAA batts for my ThermaRest Neo Air mini pump and I also use these batts for my Black Diamond Orbit mini lantern. The Revolt head lamp charges these just fine. (I happen to be charging them in this fashion as I am typing this). These work as regular rechargeable batts in any device requiring the AAA size.There is only one complaint: If the (3) black diamond batts that come with the ReVolt headlamp arrive fully charged, then why does this 4 pack arrive with an empty charge? Not a biggie.Dont listen to individuals posting bad reviews that are not smart enough to determine the difference between a faulty head light vs. faulty batteries. The batteries are just fine. Especially right out of the box.-Trav

Why do they come in packs of four if the ReVolt only holds three?They do work like the originals however and I love that head lamp more than any man should love a light that straps to your forehead.

As rechargeable batteries go, these are mediocre at best. But if you want to recharge your Black Diamond headlamp, you've gotta have them. Like HP printer ink cartridges.... Makes me think I won't replace my headlamp with Black Diamond the next time around.

The light on the Black Diamond headlamp for which I bought these batteries indicated the batteries were charged. I took off for a run and 1/2 mile later the head lamp died. When I got back home, I plugged it in and the device told me the batteries were not charged at all. Sent them back and now I used just ordinary batteries. Btw, this was my second set of Black Diamond rechargeable batteries. The ones that came with the headlamp, lasted a couple of months then stopped holding a charge. I love the headlamp except for the fact that you can only charge the batteries in the lamp is you use Black Diamond batteries. The batteries are awful.

These work great only had to replace after 6 years of having the first set.

I’ve used these batteries for two years now. I find they’re unpredictable in shelf life after first charge. Sometimes I get the “dead battery” light when trying to charge them, even after several uses. Other times they last for awhile. I have found that sometimes I can unplug them and plug them back in right away and that will kick-start the charge.

Great batteries . I tried multiple batteries in my headlamp after my stock ones died. None were as bright nor had any of them held a charge as these Black Diamond AAAs have . Only complaint wish it was a three pack since my device only needs 3 waste of one.Highly recommend besides the quantity .

Apparently you need these batteries to recharge your headlamp. Standard rechargeable batteries do not work.
