Replacement battery for Macrostream.

"I bought two of these to replace the batteries in my Macrostream EDC lights. I thought my first light had gone bad, so I purchased a new one. I tried the new battery in the old light, and it worked great. Apparently there is a limit to the number of times that you can recharge these batteries before they just stop recharging. Batteries are much less expensive than a replacement light."

— Terry H. (5/5)

"Best gear and the best price."

I need a replacement battery for my StreamLight ProTac HL USB flashlight. Do you have anything in stock??
I show that the Protac HL uses CR123's which are not rechargeable. Are you sure you have the standard HL?
