BLACK DIAMOND BD 1500 Battery | Lithium-Ion Rechargeable Power Cell | Requires BD Compatible Charger Sold Separately | Long-Lasting Headlamp Power Source (Battery Only)

Works great to charge the batteries for my headlamp. I do wish it came with a longer cable, and was USB-C connection. But otherwise it does what it's supposed to and seems to be good quality.

While it takes longer to charge than I anticipated, it holds one very well, too. I fell asleep with my Cosmo on and when I woke up several hours later, still just as bright. The blue light that indicates it’s charging is a little bright.

I have two of these lights. They are awesome, super-bright, multiple modes. The battery lasts a long time and is quick to recharge. I love the little charge indicator lights on the side. A bit pricey, but in my opinion, worth the extra money. I've used several headlamps over the years and this is by far the best! I have seen complaints about the battery compartment being hard to open. It hasn't been a problem for me. I use a small screwdriver to pry up the latch. Pops right open.

Works but is micro USB. Needs to be USB-C

This single battery lasts longer than regular batteries. If you use the headlamp often for work or camping the investment will pay for itself pretty quickly. I already had the charger for a battery I bought earlier this year so could buy the stand alone battery for my wife’s headlamp

This is a very nice headlamp. Would have been nice to come with battery pack especially given the fact that you can use a rechargeable battery. But these are really nice headlamp.

High quality. I am going to save a fortune on batteries.

Always good to have a backup battery for your headlamp as you never know when you’ll need it. Easy-peasy to charge and battery life is great. This is not your old alkaline headlamp battery, this battery is the real deal even in freezing and below temperatures.

If you’re considering this product, I highly recommend getting the one with a charger.

Funziona correttamente, comoda. Peccato che richieda caricatore reperibile da altro negozio.

Works a treat

You can trust it. Long lasting battery charge and efficient headlight.
