We wanted to deliver a battery that doesn't only only last long, but also safe for use. Weve incorporated Grade A battery cells to ensure longer battery life, durability, and lower power consumption. All of our batteries offer 1000+ recharge cycles over life of battery.

Each battery contains built in multi-protection functions such as short circuit, overheat & overload for maximum safety.

Enclosure: The enclosure is made of ABS + PC high quality material, it has high temperature resistant function to protect your laptop overheat.
Battery Buckle: The battery buckle is closely connected to the laptop, and the metal interface is stably powered.

All of our batteries are brand new and are 100% compatible to meet OEM specifications for safety and efficiency. Same size as original battery, Don't worry about assembly and adaptation issues.

Heat is the enemy: Lithium-ion batteries do not like high temperatures. Avoid placing your laptop anywhere it might become hot. Make sure your laptop's ventilation ports are not obstructed. Avoid using your laptop on a blanket or a pillow for long periods of time.
Do not discharge to 0%
Do not completely discharge and then recharge your li-ion battery on a regular basis. This is actually a destructive practice. Instead,try to always aim for the 60-90% sweet spot.Let your battery discharge to 20% (With out bottoming it) and then charge it again.

Proper storing: If not in use for long periods of time,charge the battery to above 50% and store it in a dry,cool place away from any heat sources and metallic objects.
In cases of battery bloating,stop using it,disconnect it.

New battery: For use a new battery, youd better try a few cycles of discharging to 5%. then charging up to 95%. So that it can be activated completely.
Overuse: Do not always run out of a battery to 0%, this would make it damaged or usage life shortened.
Charging sequence: when charging, first install the battery, then turn on the power, when fully charged, first cut off the power, then pull the power plug.
