FAQ

Two easy ways to find the right battery for your laptop.

  1. Laptop Model

    The laptop model is usually located on the bottom of the device, find it and enter it in the shop’s search engine.

    e.g. Asus K53SV / HP Pavilion G6 / MacBook Pro 13 A1278

  2. Battery code

    The battery code is located on the inside of each battery on the rating plate. Find the code and enter it into the shop’s search engine.

    e.g. AA-PB9NC6B/ HT03XL / CQ42 / M5Y1K

Just follow these 5 steps:

  1. Utilize the battery. Our rechargeable battery is designed for use. Continuous removal of the battery from the device does not have a positive effect on its condition.
  2. Avoid complete discharge. Today’s lithium-ion and lithium-polymer batteries are extremely sensitive to deep discharge. Repeated repetition of such a situation can cause damage to the battery.
  3. Pay attention to the operating temperature. Temperature is an extremely important factor affecting the life of our battery. To ensure optimal temperatures, you should regularly clean your laptop’s heat-dissipation system and avoid using the devices on soft surfaces (which can obstruct cooling vents).
  4. Let the battery rest. If you plan to take a long break from using your laptop, remove the battery and place it in a dry, cool place. It is worth charging it to about 50% to avoid a complete discharge.
  5. Avoid short charging times as the battery in our device has a number of charge cycles that are fixed.

The 11.1V battery cant be used interchangeably with 14.4V and vice versa. This can cause permanent damage to your laptop. When selecting a replacement battery, ensure that the voltage matches the one specified for the original factory battery. You can find this information directly on the battery itself.

A problem with charging a new battery is rare with Techie Batteries. However, if this is the case, the following video provides instructions on how to fix this:  https://youtu.be/nqPzZwoEhR0

It is absolutely correct. Voltage differences result from different measurements and the cells used. It should be noted that such small voltage differences are not noticed by our laptop and do not affect its operation in any way.

It is possible to use lower-capacity batteries. The battery capacity is expressed in milliampere hours (mAh), which indicates the working time or runtime of the laptop.
