Excellent

I've have owned the HL8R (2021 Version) head light for about 5 years now and the clip on the battery pack broke so I claimed the lifetime warranty and in absolutely no time was sent this brand new battery pack. Excellent and fast service. I absolutely love Coasts products!

Wrong product information

This product listing says: COMPATIBLE WITH: HL8R (2021 Version) But that is a lie. This battery only fits the original 2016 version of the flashlight. The battery that comes with the new flashlight is called a ZX905, but it doesn't seem to be for sale on the Coast website.

ZX900 Rechargeable battery

The zx900 rechargeable lithium ion battery performed well in cold temperatures. It is easily recharged with the included charging cable.

Long lasting

I bought this headlamp almost 3 years ago and it?s still going strong. The rechargeable battery lasts me approximately 24 hrs on medium intensity and it doesn?t seem to have degraded at all. Only problem was that over time, the battery clip got too loose and finally broke off after an accidental drop for about 6 feet, but all I have to do is buy a new battery. This lamp is definitely worth the price.

A trustworthy beacon

Always pleased with coast products, they are built to be beat up. I have used their headlamps (mostly for ten years plus and have never been dissapointed with quality or durability. Happy camper.

Great battery. I've used one for several years and it still holds a charge. The only problem I've had was a short in the wiring harness.
