Your new battery comes in a discharged condition and must be charged 8-12 hours before use. Upon initial use (or after a prolonged storage period) the battery may require three to four charge/discharge cycles before achieving maximum capacity.
When charging the battery for the first time your device may indicate that charging is complete after just 10 or 15 minutes. This is a normal phenomenon with rechargeable batteries. Simply remove the battery from the device and repeat the charging procedure.
New batteries are hard for your device to charge; they have never been fully charged and are therefore "unformed". Sometimes your device's charger will stop charging a new battery before it is fully charged. If this happens, simply remove the battery from your device and then re-insert it. The charge cycle should begin again. This may happen several times during your first battery charge.
Please try this method if the battery cannot power up: 1. unplug the adapter charger, turn off the laptop and take out the battery. 2. press the power button on your laptop for 10 seconds to release any static electricity inside the laptop motherboard. 3. reinstall the battery, plug in the adapter charger, get the laptop charged for about 6 to 8 hours. Then the battery will be activated.
For Macbook cannot power up please reset the SMC on your Macbook or please try the following steps: 1. Shut down your MacBook Pro; 2. Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected; 3. On the built-in keyboard, press SHIFT-CONTROL-OPTION and the power button at the same time. (Hold them down for about 10 seconds.); 4. Release all the keys and the power button at the same time; 5. Press the power button as normal to turn on the computer.
To discharge, simply run your device under the battery's power until it shuts down or until you get a low battery warning. Then recharge the battery.
Occasionally, BIOS updating (for laptop only) is required to make the battery work normally on your device.
If the battery will not be in use for a month or longer, it is recommended that it be removed from the device and stored in a cool, dry, clean place.
A charged battery will eventually lose its charge if unused. It may therefore be necessary to recharge the battery after a storage period.
Ensure maximum performance of the battery by optimizing the device's power management features. Refer to the manual for further instructions.
Don't leave the battery in the device with the AC adapter plugged in unless you're charging it will extend your battery life.
Do not short-circuit. Do not expose the battery to moisture or rain. Keep battery away from fire or other sources of extreme heat.
