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

It was good experience, the laptop battery was excellent and it was a good deal with this price, this was a replacement battery for my Dell Inspiron 15R 5522 model and there was no issues in fitting it. On 100% charge it was showing a backup time of 2hrs and 25 mins. Over all a good deal with this price.
