Grab yourself a backup battery for your Black Diamond.

You could hunt through every grocery store in the city and maybe not find a 6-volt battery for your headlamp, or you could just get this one from Black Diamond. This battery works with Black Diamond Ion headlamps, as well as many others from different brands.

Price resolves sadness

  • Familiarity: I've used it several times

I have the Ion because it's light. Run time isn't great, but I can milk it for weeks if I just sleep when it's dark.

Spare batteries are impossible to find, except here. The super great price compared to the local store makes it hurt a lot less - as long as you don't pay shipping.

Ion Use

I have the Black Diamond Ion Headlamp. This battery lasts about 10-12 hours with this lamp.
