FAQs
Is the battery you provide the original Compaq Presario CQ40-538TU battery?

The performance and experience are comparable to or even beyond the original battery. Compared to the original battery, we are more cost-effective. Welcome to shopping on our website.

How about the charging speed and battery life?

The main factors affecting the charging speed of the battery are the charger power and the charging environment. Therefore, we cannot give a specific charging speed. In terms of battery life, this Compaq Presario CQ40-538TU battery can last up to 3-6 hours for daily office hours(it depends on the usage scenario). However, the Compaq Presario CQ40-538TU replacement battery we offer has the same specifications as the original battery, so its charging speed and endurance are close to or even beyond the original battery.

What do I need to pay attention to after receiving the new battery?

Storage: If you do not intend to use the battery immediately, please store it in a dry, cool and well-ventilated place and recharge it regularly to maintain optimal performance.

How to replace my Compaq Presario CQ40-538TU battery?
