But for Ni-Mh and Ni-Cd batteries, it's better to drain the power completely (use it up) before recharging especially with Ni-Cd batteries due to its tendency to have memory effect. However, it is helpful to the batteries' performance to regulary discharge them completely before recharging again, especially for laptop computer users.
- Q: How do I judge the quality of rechargeable batteries?
A: There are many different battery testing criteria and standards such as battery's internal resistance, testing the capacity and life cycle with different C-rate and environment temperature, etc. Most of them require specialized equipment and controlled enviroment to conduct the tests. Therefore, regular consumers really cannot just the quality of rechargeable battery from their outside appearance. But from BatteryX's experience, Japanese made cells have tighter tolerances, closer in performances meeting their designed specifications, and higher life cycles.
