Welcome to a Laptop Battery specialist
of the Toshiba Laptop Battery First post by: www.itsbattery.com
Today’s battery research focuses heavily on lithium systems, so much so that one could assume that all future applications will be lithium based. This lithium hype is especially apparent when attending battery conferences where laptop battery manufacturers from all corners of the world meet to present their latest achievements. Just a few years ago, the argument was NiCd against NiMH; then the speakers argued on the benefit of Li-ion over NiMH and today the emphasis is on Li-ion Polymer. The Nickel Cadmium (NiCd) and Nickel Metal Hydride (NiMH) are hardly mentioned.
When buying a replacement Toshiba Battery such as Toshiba PA2487U Battery, Toshiba PA3107U-1BRS Battery, Toshiba PA3383U-1BRS Battery, Toshiba PA3384U-1BRS Battery, Toshiba PA3285U-1BRS Battery, Toshiba PA3191U-1BRS Battery, Toshiba PA3166U-1BRS Battery, Toshiba PA3331U-1BRS Battery, Toshiba PA3098U-1BRS Battery, the buyer often has the choice of different toshiba battery chemistries. Li-ion and Li-ion polymer batteries are used on newer laptops, whereas the NiMH and NiCd are found in older models. If the buyer has a choice, the sales person may advise a customer to go for the highest capacity rating and to stay away from the NiCd because of the memory effect. The customer may settle for the slim-line NiMH because it offers relatively high capacity in a small package and is reasonably priced.
The NiMH offers good value for the price but falls short in expected cycle life. The Li-ion is most economical for those who use a notebook daily. Up to 1000 charge/discharge cycles can be expected if used within the expected service life of about two to three years.
The Li-ion is a low maintenance battery which offers high energy, is lightweight and does not require periodic full discharge. No trickle charge is applied once the battery reaches full charge. The Li-ion battery can stay in most chargers until used. The charging process of a Li-ion is, in many ways, simpler and cleaner than that of nickel-based systems, but requires tighter tolerances. Repeated insertion into the charger or cradle does not affect the battery by inducing overcharge.
Switching to environmentally friendlier batteries is fitting, especially in the mobile phone market where the NiMH performs reasonably well and can be economical. The battery disposal issue is difficult to control, particularly in the hands of a diverse user group.
