Laptop Batteries You Won't Have to Replace for at Least Three Years

Leyden Energy has announced a new lithium-ion laptop battery that is said to hold its full charge for at least three years and will be backed by a three-year warranty. This is great news (if the claims are true), since most laptop batteries really suck.

If you're a laptop user, you probably know the frustration of your laptop slowly and surely providing fewer and fewer hours of battery life. After about 12 to 18 months of use, most laptop batteries need to be replaced since they no longer hold a charge. Besides being an added cost and inconvenience, replacing batteries so often has a negative impact on the environment.

Leyden Energy says its long-lasting battery has one of the highest energy densities and run times for a lithium-ion laptop battery. For instance, the companys says the battery can be charged more than 1,000 cycles and has the ability to operate at higher-than-average temperatures.

The Leyden battery will cost more than standard batteries (which usually come with a one-year warranty), but will cost less than double the price of a one-year battery. Canadian battery retailer Dr. Battery will be one of the first to offer this long-lasting battery, with more retailers hopefully being added soon.

HP has a similar long life battery offering, in partnership with Boston Power, but it's only available in certain models (and, of course, only for HP laptops).
