The battery in my Black Diamond head lamp finally depleted its charge. I looked around for a charger and ran across this product... a charger that came with a higher amp rated battery than my original. This is a no brainer... I highly recommend this product.

We got the onsight 375 for this battery and it works very well. Should NOT BE A SEPERATE PURCHASE... they should be marketed together as a kit... DO BETTER BLACK DIAMOND! Once together, they are bright and easy to wear. A little difficult to get battery out of light and out of its charger.

I added this to my Onsite headlamp and it has been great. It is nice to not need to mess with aaa batteries and increased capacity.I wish the charger was USB C

It sure is nice to have one on the charger, and one in the light. Saves money on batteries if you use your light for long periods of time.

First of all, this headlamp gives great light. It is lightweight, easy to carry and easy to wear. It seems to last quite a while on regular batteries. All in all a great unit. I was greatly disappointed with the price of the rechargeable battery unit that needs to be purchased separately. My son really wanted to the re-chargeable battery. He lived in the north woods of Maine for the summer and wanted the versatility of both power sources. When you add in the lamp plus the rechargeable battery you nearing the $100 price point. There are many other units out there that come with the rechargeable battery that are likely just as good for a lower price.

I'm not a fan of the AAA form factor, especially when a product asks for 3+ AAA batteries. So much is wasted to the casing of the cells, adding unneeded weight and space for the same mAh rating. And let's just hope you have 3 AAAs. I hate digging around through my backpack and finding I only have one or two batteries left.This is a nice alternative compared to alkaline, NiMH, and single-charge Lithium batteries. Less weight, great mAh rating, and you only have to keep track of a single battery. Throw an extra in your pack just in case.To compare to the best AAA batteries out there:3x Energizer Lithium Ultimate AAA 1.5v @ 1250mAh: 5625mw (Single Charge, lightweight)3x Energizer Max Alkaline AAA 1.5v @ 1150mAh: 5175mw (Single Charge, heavy)3x Energizer NH12-700 NiMH 1.2v @ 700mAh: 2520mw (Rechargeable, heavy)1x BD1500 3.7v @ 1500mAh: 5500mw (Rechargeable, lightweight)So essentially, you're getting the performance of Energizer Lithium Ultimate batteries in a rechargeable form, saving you money, convenience, and time in the long run.Granted, Energizer Lithium Ultimate batteries are going to have superior performance over Li-ion in extreme temperatures, and don't loose charge sitting over time. They're also very lightweight. So if you're going to be using these batteries under 0C/32F, or have your light and batteries in a bug-out bag/emergency kit, you might want to consider Energizer Lithium Ultimate cells.If you don't have BD lights, this product isn't for you, don't buy it expecting to use the battery for other things unless you're a mad tinkerer.

It's silly to use a proprietary battery like this. Why not use a more standard battery instead of this proprietary bs? I didn't spend $75 on a headlamp just to shell out another $24 for this.
