eli5: Why do regular batteries last for so long whereas rechargeable ones have to be recharged so frequently?
In: Technology
Some hold less energy but also the chemicals in rechargables produce a lower voltage (1.2v instead of 1.5v) lots of devices will detect rechargables as less than full battery even when fully charged since the voltage is lower. On top of that the voltage might drop below operational threshold sooner since they start lower.
To add to that regargables degrade over time so eventually they hold less charge and wear out with greater frequency.
