Perform Shallow Discharges; Avoid Frequent Full Discharges. Old NiMH and NiCd batteries had a âmemory effectâ and had to be completely discharged from 100% to 0% to keep their capacity. Modern devices use Lithium Ion batteries, which work differently and have no memory effect. In fact, completely discharging a Li-ion battery is bad for it. You should try to perform shallow discharges â discharge the battery to something like 40-70% before recharging it, for example.
