The new battery is similar to a new knitted jacket: as one at the very first day of socks stretches and takes the shape of the body of its owner, so the other at the very first charge receives the energy content that you ask it.
Instructions
Step 1
Insert the battery into the device immediately after purchase. Turn it on and do not turn it off until it sits down and turns itself off. If you charge a new battery not fully discharged, it will signal a full discharge at the level of charge that you will set it now.
Step 2
Insert the battery into the charger according to the polarity: plus to plus, minus to minus. Plug the device into a power outlet.
Step 3
Leave the batteries until fully charged, for the time indicated on the battery packaging. Do not leave them all day or all night, otherwise the energy intensity will decrease. It is also impossible to remove the batteries until they are fully charged: the next time they are charged, the battery will pick up current to the same incomplete level.
Step 4
Discharge and charge the battery in the same way several times: first until it is completely empty, then to the brim. After that, the energy capacity of the battery "stretches" to the proper volume, and it can be used fully.
