Manufacturer customized 11.1V42A lithium battery pack medical
device battery pack
How long can the medical device battery pack last?
Medical device battery packs will last for 2 to 4 years, depending
on storage, usage conditions and capacity. If you use the battery
pack more or store it improperly, the battery life will be
shortened.
How many times can the battery pack be charged?
The battery pack can go through 300 to 500 charging cycles before
it starts to lose battery capacity.
