Questions about this item
How can I confirm the battery is working correctly after installing it in my Asus U43Jc?
After installation, the laptop should power on using only the battery, show a 10.8V charge level in the operating system, and hold a charge consistent with the 4400mAh rating during normal use.
What comes in the box and do I need any extra parts to fit this Dr. Battery A42-U53?
The box contains the replacement battery only; no tools, cables or adapters are included. You reuse the existing screws and connectors from your Asus laptop.
Which version should I choose if my original battery is labelled A32-U53?
This battery replaces Asus part numbers A31-U53, A32-U53, A41-U53 and A42-U53, so it matches the A32-U53 label directly.
