Battery Pack Replacement for LR40R
"Batteries seem to work excellent. I currently have a LR40R that one of the batteries died. I purchased 4 new 3500mAH that seem to work perfect however my LR40R will still power down after about 10 secounds on any mode other than low. I thought that the new batteries would fix the problem however I think it's the lights electronics. Side note: I have had this flashlight for many years and it has seen allot of use, I would buy one again with no worries."
Excellent quality lights at fair
"Excellent quality lights at fair prices. I have a headlight, a rifle light and handgun lights. Every light is intelligently designed and very user friendly. I especially like the battery charging circuits are built into the batteries and don’t require a special charger. The headlight, rifle lights and handheld lights have a charging port built into the housing. Best hiking and weapon lights on the market."
Apt for purpose
"Good !"

Great batteries
"Using it for my thermal imaging device and it works great."
“Just what the doctor ordered”
"“Just what the doctor ordered” Thank you."
New Battery 3500
"Installed new battery. It will charge but blinking red light indicates something is wrong. These are expensive batteries and expected more."

"I have many of these same batteries, this one seems to be just like the others. Lasts a good amount of time with lights on high"
It’s great
