Title: What happens if we re-charge a Lithium-Ion battery when it is not fully used? Post by: ilocanababy on Sep 27, 2012 Does the life-time of the battery shorten if we keep re-charging it when it's half-full ?
For example the electric-fueled car producers claim that we don't have to go to the fueling stations anymore, we can just re-charge our car in our house with a power supply. However, eventually, we will have to recharge the car several times when the battery is not completely empty. Does this have a negative impact on the lifetime of the Lithium-Ion battery?

Example.. Your battery when new lasts 2 hours. You use it for an hour... you charge it... Now the battery thinks that when fully charged, it only lasts an hour... Why, I do not know, just know what happens... Title: What happens if we re-charge a Lithium-Ion battery when it is not fully used? Post by: tomsawyer on Sep 27, 2012 Lithium-ion technology does not suffer from the "memory effect" that some of us remember from the old Nickel-cadmium batteries. LI will handle a partial charge-discharge cycle without any long term problems.

Li-Ion batteries may suffer from repeated deep cycles (completely discharging then completely charging), although I'm not 100% sure. Anything else should be fine, though.

Most other types of batteries do better with frequent slow charge. Lithium ion batteries are better in almost all ways. Disadvantages are initial cost, lithium ion batteries deteriorate if they are excessively discharged below about 3 volts, or excessively charged over about 3.7 volts, per cell. Computers can solve these problems before the deterioration begins, but experienced humans can coax some more usable life out of partially deteriorated lithium ion batteries. Neil
