Since lithium-ion is different than nickel and cadmium-based batteries,
how should we take care of lithium batteries?
Don't try to fully discharge the battery packs
frequently. This only adds strain. Several
partial discharges (regular use) with frequent
recharges are better for lithium-ion than one
Recharging a partially
charged lithium-ion battery pack does not cause
any harm because it has no "memory".
Short battery life in model airplanes is more
likely to be caused by heat rather than
charge/discharge patterns. Keep the
lithium-ion battery cool. Avoid a hot car, for
3. Don't charge up
the battery pack just to store it away.
When storing for long periods of time,
keep the battery at a
40% charge level.
Consider removing the battery from a laptop when
running on fixed power. (Some laptop
manufacturers are concerned about dust and
moisture accumulating inside the battery
Use the right charger.
By now you probably know that each kind of
battery has its own technology, its own rate of
charge and so on. Charging lithium packs
correctly is one way to extend their life and to
avoid damage. The NMP lithium-ion charger
is designed specifically for charging the NMP
lithium-ion battery pack safely, on the bench,
in the field, or in the car.
Don't use old
batteries. Avoid purchasing
spare lithium-ion batteries for later use.
While it makes perfect sense to have 2 or 3
extra battery packs, so that you always have a
fresh one charged up and ready to go, it isn't a
great idea to just buy up batteries and keep
them around for years before using them.
