How to install a new battery?
1. You need to turn off the laptop and disconnect the power at the same time.
2. Disconnect the old battery from the motherboard to avoid unnecessary damage caused by disassembling the battery. Then unscrew the old battery and save it.
3. Take out the old battery, install the new battery on the battery box, tighten the screws, and connect the wires of the new battery.
How to maintain a laptop?
1. New battery: When using a new battery, it is best to discharge to 5% for several cycles. Then charge to 95%. So that it can be fully activated.
2. Excessive use: Do not deplete the battery to 0% often, which will cause damage to the battery or shorten the service life.
3. Charging sequence: when charging, first install the battery, then turn on the power, after fully charged, first cut off the power, and then unplug the power plug.
4. Long-term storage: Please fully charge and store unused batteries. (Charge once a month) Do not store in low battery to avoid reducing.
What should be noted when using the battery?
1.If your computer will not be used for a long time, it is recommended that you remove the battery and store the battery separately.
2.It is recommended that you store the battery in a dry environment with a temperature range of -10--35 degrees Celsius, and avoid sunlight.
3.As the damaged lithium-ion battery will pollute the environment, it also has a certain degree of danger. Please do not disassemble or discard at will.

But it won't lock onto my Laptop.........I was able to charge per instructions and after a couple weeks it still showed 96% which is probably about normal!! Haven't tested Battery Life yet but will soon!!

1. 52000 mWh description is Very optimistic- 48840 mWhdesign capacityfull charge 40804 mWh after draw down and recharge. Settled in at 40115 mWh from 11/13 thru 12/3.Essentially, this "new" battery was delivered with a 17 % wear factor. It is now 18% on 12/4.It is, however, constructed with SONY cells.2. If the computer charger is connected and the computer is off, after a day or so the battery charge indicator will start to flash indicating a charging problem. Unplug it for a while, problem clears- but comes back. So, don't risk it and unplug after fully charged- or as much as it will take.3. There is only a 30 day return window- so, run a battery report when you install the battery, cycle the battery per instructions, run another battery report. If the battery does not charge close to design spec, return it.4. On the plus side, it is shiny and fits perfectly.I

Considering the age of my laptop, I'm happy that batteries are still available. Installation is a breeze and I followed that manufacturer's advice regarding nearly full discharge prior to full charge for the first time.
