Laptop batteries with premium cells

Laptop batteries with premium cells

AVACOM has come with notebook batteries built from PANASONIC and SONY high-capacity cells. These batteries have the same dimensions and weight but up to 32% more capacity than the original ones. For instance a 6-cell battery with a capacity of 4400mAh is now available with a capacity of 5800mAh due to these new cells. The cells from which these batteries are assembled have a longer life than most types of cells used by renowned laptop manufacturers.

Batteries made of high-quality components

The battery is a sophisticated device with double protection which controls the charging of individual cell strings while protecting them from overcharging and discharging. With batteries that contain high-capacity cells, your laptop's battery life will noticeably increase so you no longer have to carry your power adapter even to longer meetings.

How to keep the battery in good condition

How to keep the battery in good condition

When the battery is made, it is partially charged, yet its capacity and performance are below 100%. Therefore, for optimal battery formatting, it is recommended to repeat the full charge and discharge cycle at least 3 times at the beginning. A permanent connection to the power supply diminishes the battery's capacity so we recommend that you disconnect the device from time to time. If the battery is not in use, store it in a dry place and check and recharge it approximately every six months.

What damages the batteries

One of the most common causes of battery degradation is when you lay it aside completely discharged and don't use it for a long time. Don't expose the battery to temperatures over 60°C. If the battery is exposed to temperatures below 5°C, charge it only at room temperature. Only use the battery with the devices it is intended for. Also make sure that the battery does not suffer short circuit or higher discharge currents. Protect it from mechanical damage, chemical agents and moisture.
