How to Replace Laptop Batteries
Laptop Battery Guide
Just like there are many different makes and models of laptops, there are also different technologies used in laptop batteries. Whether you're purchasing a replacement Dell laptop battery, looking for spare external laptop batteries, or trying to get every last ounce of juice out of your current HP laptop batteries, it's important to know which technology is compatible with your specific laptop. Knowing this will help you decide not only what kind you need, but also how to keep it clean and healthy, and maintain a nice long battery life through proper care.
NiCd - Nickel-Cadmium
This is the first technology ever used in rechargeable laptop batteries. These feature Nickel-Hydroxide electrodes with Potassium-Hydroxide as the electrolyte. NiCd laptop batteries do last a decent amount of time before you have to replace them. However, they are known to be much heavier than the ones most of us are accustomed to and will add extra weight to an already heavy laptop.
NiMH - Nickel-Metal Hydride
This technology is found in many laptops today. They last 40 percent longer than NiCd laptop batteries and use the more environmentally-friendly metal alloy rather than toxic Cadmium. While Nickel-Metal Hydride batteries also suffer from "memory effect," they last much longer before this happens. You can charge NiMH laptop batteries up to 1,000 times before having to replace them. These are more likely to lose a charge when you don't use them for a while than a battery using modern technology. Keep in mind: Use it or lose it.
Li-Ion - Lithium-Ion
Lithium-Ion is the most well-known and commonly-used laptop battery technology today. They don't suffer from "memory effect," and last longer than other batteries available. They don't have to be discharged completely to maintain their battery life and really work well if you charge it after use rather than use up all the power first. Li-Ion batteries won't weigh down your computer because they are made of lightweight cells.
