Review on High Performance EBL 8 Pack 1200MAh 1.5V AAA Lithium Non-Rechargeable Batteries - Ideal For High-Tech Devices With Constant Voltage by Tre Boyer

These in theory have the potential to be a 5 star product but not with ignorance. I hope my review can help inform others. Putting myself in survivalist situations, I always check my batteries with a meter before going into the vast outdoors. I bought these for their superior cold weather performance but did not realize at the time the concept of their constant voltage. What does this mean? You cannot use a device like in picture to check the charge. They will always show full charge until it is too late. I assume the only way around this is to log your hours of usage! Wow what an inconvenience. If someone knows a way to check the charge, please let me know through a review or in the Q&A section
