Review: Short battery life - Only lasted 3 months Review: Works fine with my Theradome LH40 that I purchased 4Q20 - has thermistor on center lead - This battery works fine with my LH40. I tried a battery from another seller and it didn't work - it gave me power but it wouldn't charge. I figured out it was because the center lead did not have a thermistor on it - the resistance from ground pin to center pin was "open circuit." So, my LH40 wouldn't charge because it did not know what the battery temperature was. So, I asked if this battery had thermistor on center lead and was told it does - so I ordered it. My old battery had a resistance of about 8.8 kilo-ohms from ground pin to center pin. If your Theradome's battery does also then this is the battery you need to order. ## Features - Compatible Models: Theradom e LH40, LH80, LH80 Pro; Compatible Original Battery Part No.: INR18650-1S1P - 100% Compatible with original battery; 180 days warranty - Capacity: 2600mAh; Nominal Voltage: 3.7V - Battery Type: Li-ion battery; Safe and reliable battery certified by UL, CE, UN38.3, RoHS - Over 300 times cycle life; Long working time ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0B9RL5D9M | | Batteries | 1 Lithium Polymer batteries required.
