One of the key features of a Digital Audio Player (DAP) is how long its battery can last. In the pursuit of extending the battery for DAP, I found out that some seller on Aliexpress sells high-capacity batteries that is 50% higher than the original batteries.
The 2 batteries that we will be studying today are:
YKaiserin 2100mAh Battery for Sony Walkman NW-A10x
Normally for Sony Walkman NW-A105 (the one I owned), the standard battery capacity is 1285mAh. The battery by YKaiserin is claimed to be 2100mAh, which is around 60% additional compared to the original one. You can refer to this post on how I add a 2nd battery to my NW-A105.
HSABAT 4800mAh Battery for Ibasso DX160
For Ibasso DX160, the standard battery capacity is 3200mAh. The battery by HSABAT is claimed to be 4800mAh, which is 50% more compared to the original one.
