Replacement for Asus U33, U42, U43, U52, U53 series

This new Dr. Battery unit replaces original Asus batteries across the U33, U42, U43, U52 and U53 families. It fits models such as U33J, U42F, U43Jc, U53SV and the A31-U53, A32-U53, A41-U53 and A42-U53 part numbers. Buyers who need a battery for a different Asus series or another brand should look elsewhere.

10.8 V 6-cell lithium-ion chemistry

The single specification that decides fit is the 10.8 V output combined with a six-cell lithium-ion design. Your original battery must show the same voltage and cell count; a different voltage or cell configuration will not work in these laptops.

4400 mAh capacity with 48 Wh energy rating

This capacity delivers a direct like-for-like runtime for everyday office work, web browsing and media playback. It will run out sooner under sustained heavy loads such as gaming or video rendering where the original higher-capacity packs would last longer.
