Most laptops today are powered by Lithium-ion (Li-ion) batteries. These are a great alternative to the older technologies because they have a a lot higher power to weight ratio, are not prone to the memory effect phenomenon and are inherently more environmentally friendly. Nonetheless, a lot like the older battery chemistries, they do have a limited lifetime. Despite the fact that the older chemistries rates of failure had been proportional to the number of charging cycles, the capacity of today's Lithium-ion batteries diminish with age.
When you locate that your laptop laptop or computer doesn't hold its charge as lengthy as it employed to, or when your system's power management utility software indicates that its charge level is decreasing, you will need to have to come across a replacement laptop battery to maintain your computer's operating time.

These higher capacity generic batteries typically price much much less than the OEM's standard capacity battery.
Generic laptop batteries are produced at the exact same manufacturing plants that originally produced the laptop battery for the computer manufacturer; batteries are simply an out-sourced item for the personal computer maker. But these batteries may perhaps also be made at facilities whose standards aren't as high as the primary plant's plus the only way to ensure that you might have bought a top quality battery is to check the reputation of the supplier or the seller, ensure that they provide a liberal warrantee and test the battery by charging it within your computer soon after it really is received.
