My laptop is 7 years old (bought in november 2012) and I've had 1st battery ever since. Whenever I plugged it into power plug, I always removed battery. Even though, after 7 years of use the battery lasts ~1h, while laptop works perfectly. I decided to change 18650 batteries in the battery pack, but here's the catch: Original battery's specifications are: 10.8V 4700mAh 50Wh.
I would like to remove all 18650 batteries and replace them with new, better ones, such as Samsung INR18650-35E 3450mAh. Here's the thing: Could there be a problem with replacing old (original 18650) batteries with new 18650 batteries, which has higher energy charge than the original one had? I am talking about laptop power supply, battery charger unit and anything else, perhaps?
