I have a Gigabyte Q1000C mini Laptop. The Bios battery is dead, as it has been in storage for the last 3 Years.

The bios battery in it now is a ML 1220 - as shown above. I'd like to know if I could replace it with a CR 1220? The current one is rechargeable. I believe the CR versions are non rechargeable.

Do not want to try it and damage the Laptop. The ML 1220 versions are just not available around my area I stay.

According to a quick search using the battery identifier, Amazon and Walmart (online) both have this particular battery available. Walmart indicates one remaining, while one of the Amazon sources show ten. Both locations reference rechargeable capability, ensuring the safety of your computer. One type shown requires soldering, while another appears to be the slip-in type.

Damage the laptop - indirectly. Damage the battery - probably.

Your motherboard will still try to charge the CR1220. Putting such voltage across a non-rechargeable lithium cell is not a good idea.

Apart from overheating, it could damage the battery. Worst case, it will catch fire.
