Batteries
Purchasing another battery can be useful for people who find themselves regularly away from a power point and requiring extended battery life. Batteries also degrade over time as you charge and discharge them, their performance will decrease slightly with every charging cycle. After 12-18 months you may notice the performance of the battery has significantly reduced by as much as 30% if you are a heavy user, this would be another situation where a replacement battery could be a good alternative to purchasing a new laptop.
