I would like to know how many volts a bios battery has in a laptop. Because I think that's why my laptop is on strike.
Usually they have 3V, but if you remove them you can read up on them, it says on the battery.
3? I think it also says (normally) how much V the (original) battery has
I agree. In addition to the voltage, the format must also fit. 2032, 2025 and 2016 are common / common. But it says on the battery.
3 volts normal. But there's usually no built-in laptop because it has a battery anyway.
You have to see what is built in, usually a CR2032 (like the PC too) that comes with 3V.
This is an ML 1220
3V has your battery
Just enter ML1220 battery into Google
If it is not readable, you can also measure. However, the measuring device should not be made of metal, or the metal parts that come into contact with the battery should be taped, e.g. With Tesa. The nomenclature of these button batteries is simple. CR2032 means the battery has a diameter of 20mm and is 3.2mm thick. At 2025 the diameter is 20mm and the battery is 2.5mm thick.
