How can you handle the batteries? I think
you must have a couple of batteries, such as 18350, 18650, 18500 and 26650 etc..
Maybe you will use 26650 Stingray X mod for a few months. In this situation,
what can we do with the others batteries?
One characteristic of lithium ion batteries
is not very good, that is a lithium ion battery aging, if we stored in the
lithium-ion battery in a period of time, will permanently lose some of its
capacity. Cos the lithium-ion battery anode material has already begun its
failure history once produced from factory, different temperatures and charged
state have the different consequences of its lifespan. The following data is
taken from references, percentage means capacity of the battery:
Storage temperature
|
40% state of charge
|
100% state of charge
|
0 degrees
|
98%(1
year later)
|
94%(1
year later)
|
25 degrees
|
96%(1
year later)
|
80%(1
year later)
|
40 degrees
|
85%(1
year later)
|
65%(1
year later)
|
60 degrees
|
75%(1
year later)
|
60%(3
months later)
|
Thus, the storage temperature is higher and
the more full battery charge, the more severely loss its capacity, it is not good
for long-term preservation of lithium-ion batteries. Instead, manufacturers
should be treated batteries like food and recall the out of date lithium-ion batteries;
users should pay close attention to battery production date.
If you have idle batteries, we recommend
storage conditions for the charge level is 40%, the storage temperature is
below 15 degrees or lower.
The nickel-metal hydride batteries and
nickel-cadmium batteries are almost far away from the aging effects; long-term
storage of nickel-based batteries can be restored to its original capacity
after making several deep charge and deep discharge.
