Should Lithium Ion Batteries Be Fully Discharged Before Charging. Yes you should use a recommended charger to charge a Li-ion battery. They should be kept at charge levels between 30 and 70 per cent.
Therefore the complete discharge of lithium batteries is a dangerous process. Every 30 cycles or so should be enough. Whenever the situation allows only apply a full discharge to adjust a savvy battery and to forestall memory on nickel-based batteries.
Where they become different in charging profiles is Stage 3.
Although lithium ion cells have what is termed a calendar life - their lifetime in terms of elapsed time even if they are not used another major factor is the number of charge discharge cycles they can accommodate. You may need to discharge it fully occasionally to recalibrate the capacitiy measuring electronics in the accumulator. Do not wait till the array is empty before recharging it. It seems like theres always contradictory tech advice going around.
