1/2 AA Size LS 14250 ER14250 3.6 Volt 1200 mAh Lithium Batteries 4 Pack, Tyrone Batteries Compatible for Dogwatch Dog Collar and Some of Movement Monitor/Home Security System/Alarm System

These ER14250 batteries are excellent! I needed replacements for my smart meter, and these worked perfectly. They hold a strong, consistent charge and come well-packaged. The price is great for a 4-pack, especially considering they’re lithium. Highly recommend if you’re looking for reliable, long-lasting 3.6V batteries.

The battery size is correct for my room's motion sensors, with a voltage of 3.6V. I replaced the old batteries without any issues. The product page claims a 10-year battery life, and I hope it lasts that long.

Exactly what I needed. Hard to find locally

Revived prmomty and they appear to be correct but I purchased as reserves so I haven’t actually used one yet

The order was for 4 batteries. The day they were received they were installed in two motion detectors. The following day I was getting error reading for them. Since I had just put in “new batteries”, the alarm company figured that the detectors needed replacing and made a service call- only to find that the batteries were dead. So these stupid batteries will end up costing me about $150 for a service call. Not happy.

Good price good quality, best value for the money.

Unlike two other brands of batteries of this size I bought through Amazon, THESE 1200ma BATTERIES CAME FULLY CHARGED AND ACTUALLY FIT IN MY DEVICE. All of the “other brands” eight batteries I purchased arrived either stone dead or ALMOST dead. Additionally, I had to peel the labels off of 1/2 of these other “brand X” batteries to reduce the diameter enough to fit them in my device! I HIGHLY RECOMMEND THESE TYRONE ER14250 3.6 Volt 1200 mAh Lithium Batteries. THEY FIT AND WORK AS PROMISED! Should I need more, I WILL DEFINITELY BUY THIS BRAND AGAIN!
