Battery Seems Fine...
April 5, 2021
I bought this 17670 battery to replace two cr123 batteries in my older model streamlight protac HL headlamp. While the battery fits fine, the voltage is too low and the light does not work. This is no fault of the battery. This headlamp requires the voltage of two cr123 batteries in series, 6v, to operate.

Does not power my older SureFires
June 21, 2020
Does not work in my (late 80s? early 90s?) 6P or early 90s 12Z SureFires. But I do have a (mid 90s?) 6Z that it powers, although not as bright as 2 CR123s (which is ).

An excellent choice

I use flashlights all day every day. I keep a Streamlight 2xCR123 on me and chose a model that couldn't take 18650s because they are significantly larger. This battery last longer than 2 CR123 rechargeables and has worked reliably every day for over a year.

Great batteries and nice fit in tight flashlights

I have other ultrafire 17670 batteries. These seem a bit slimmer where the protection circuit is installed. This allows these batteries to fit easily in a Surefire G2 and Surefire 6P whereas the the older ones I have are either tight fit or unable to fit. I have a couple of other lights that I have never been able to get a full size lithium ion battery to fit and these fit quite well. Thanks

Okay battery

I bought this battery to run in my elzetta flashlight. I use my elzetta flashlight around the house alot and got tired of going through cr123 batteries. A 18650 won't fit so I bought this one. The charge holds okay and is okay for use around the house.

Perfect for high output LED lights that won't take 18650's

This will be ideal for your compact LED light that can't use an 18650 but your runtime will be less... still beats the RCR123A's though.

ConsShorter runtime than std. CR1323A's

Nice battery!

This thing is great, I run them in my P60/G2x/Fury/NCP12/M18 striker,and they are perfect. I have been running them for almost 3 month with many cycles. Don't hesitate to save tons of loot.

reliable and cost effective

I purchased 2 of these 17670\'s a few months ago for my eagletac p20c2 mkII and they have worked very well. When they eventually die i will not hesitate to buy another pair from this site. My only complaint is that one of the batteries had trouble fitting into my flashlight because the plastic cover was a bit too thick in certain areas, but i quickly solved the problem by fileing down the thick areas with a nail file. 5 out of 5 for delivering good quality and reliability for a fair price.
