I need to buy a new battery. The model of the battery is Li-Ion Battery Pack A41-K53. Rating = 14.4v 2600mAh, 37Wh. I searched and found the same model, but voltage and mAh is different. The voltage of the new battery I looked is 10.8 and mAh is 4400. If I bought that battery, would I have a problem? What are other things I should care about?
On some batteries you can go up to 10% +, but no -. But this battery is probably not going to work OK.Yor laptop needs 14.4 and you wanr 10.8 as far as I see. So you MBO,processor, RAM and everythin else will have 3.6v in lack of.
You need to put battery with the same voltage(up to +10% is OK on most of new batteries) and capacity is not important. And size must be the same. I mean you can not put bigger battery in smaller slot. And it need ti be cerificated by laptop manufacter or you can lost warratny and put yourself in risk.
If it has the same model but not the same voltage, it's not good enough.
Requirements to look for:
- It has to fit in the battery slot. So check the dimensions and the connector.
- It has to be the exact same voltage. While it's technically possible at times to use a differing voltage, you really only want to do this when you're sure what you're doing and can tackle the risk. Considering the only modes of failure with Li-ion batteries (all modern laptop batteries) are flames, smoke and explosions, you really don't want to do that.
Amperage-hours (in mAh) is basically the storage capacity. More mAh is like having a bigger gas tank in your car: when completely filled up it takes longer before you have to recharge. So a 2600 mAh is good, but a 4400 mAh has more capacity. Keep in mind that the useful capacity is 0 if it doesn't fit and has the wrong voltage, so those requirements are much more important than the amperage-hour rating.
