SUKAI1200mAh AAA Lithium Battery, 1.5V Disposable Lithium Ion Battery - Long Life, High Power, Light Weight, AAA Batteries (Non-Rechargeable) 8 Pack

Cost per length of life is excellent in low drain electronics. Not sure about high drain. In motion sensors, remote controls, etc. wow, these far outlast alkaline.

Just installed these in my wifi security system sensors at my vacation house.. I expect longer battery life than normal alkaline batteries and not have to worry about my system going down while no one is home.

Worth the buy

so far, so good

My rating is based in the voltage measured using multimeter. There are variations among the cells tested and all were around 1.59V to 1.65V. This is lower than Energizer’s Lithium which are consistently at 1.72-1.74 Volts and 1.66-1.70 Volts for EBL Lithium batteries. No longevity data but lower starting Voltage may suggest shorter or lower usable energy stored in each cell

Longevity not yet known but am assured it will not leak and ruin my devices.

So far , so good

Battery provides power
