How To Store A Canon Bp-827 Camera Battery Properly?
While the high temperatures inside modern cameras are probably the worst enemy of
a Li-ion bp-827 battery, frequent discharge/charge cycles will negatively influence a batterys life. If your camera is one replacement, then you probably only need the battery every now and then. It can be quite frustrating if you want to use your camera for the first time after a year without charger, only to realize that your bp-827 batteries are already dead even though you never really used them. However, if you remove the battery from the camera and store it accurately, there is a good chance that it will be in good condition when you need it next time.
Dont store a battery that is almost empty. Stored batteries continue losing energy, albeit at a much slower pace. If the stored battery is totally discharged, it could be destroyed.
Dont store a fully charged battery. Fully charged batteries deteriorate faster than half-charged batteries. Most articles Ive read recommended storing laptop batteries with a 4060% charge.
Store the bp-827 battery at a low temperature. I usually put it in the fridge. It keeps my battery fresh and crisp. Check out this table at Wikipedia. 0C (32F) seems to be the best storage temperature. I wouldnt put the battery in the freezer even though Li-ion batteries only freeze at approximately 40C.
Store the battery in a dry place. A moist environment will accelerate discharging the battery
Check the battery state every now and then. I would remove it from the fridge at least every 30 days to calibrate it (fully discharge and charge).
Let the bp-827 battery warm up a little before you put it back into your camera. If the temperature is raised too fast, it will strain the battery.
