12: Memory effect of lithium-ion batteries Part 2

Measures to prolong the life of lithium-ion batteries
To prolong the life of lithium-ion batteries, the following can be done.

  1. Do not perform over voltage charge, large current charge, large current discharge
  2. Do not discharge in over discharge
  3. In terms of preservation,preserve reduced charge amount as much as possible at constant temperature.

Although 1 and 2 cannot be controlled as they are product specifications, 3 can be countermeasures, but if charge amount is reduced recharge is necessary when in use.
Constant temperature preservation does not mean to put lithium-ion batteries in the refrigerator.

Lithium-ion battery cell is ideally kept at about 25°C so as not to cause a short circuit.

Do not leave other lithium-ion batteries at high temperature.
For example, it is effective to prolong the life of lithium-ion batteries by not leaving devices using lithium-ion batteries at a high temperature environment and so on.
