Camera - a fragile thing, prone to all sorts of harmful influences. If you want it served lithium stock for a long time then pay attention to the mechanical structure.

Laptop computer uses If you keep the lithium bettery stock battery in your laptop for everyday use and power it from the wall socket unplug the power every few days and let it run off the battery as a battery at capacity lasts longer than one at capacity if you don't travel with it you should remove the laptop battery when on fixed power.
Now you want to discharge the battery. If you disable the hibernation setting or anything else that might make the computer go into power saving mode, it would be better. Let the computer run until it shuts down due to loss of battery power, then turn it back on.
Recharge the battery to full again and repeat the above steps a few more times. This will allow you to use the battery for a longer time and you can do this no more than once a month. Replacement batteries can be expensive and stretching out their use when you are on a budget can help.
