These battery types are there:
The Nickel-cadmium battery (NiCd) is one of the veterans. It is characterized by a long life expectancy, high robustness and fast loading times. Low and high temperatures it can during the operation of less harm than other Sony battery. The disadvantage: Cadmium is a harmful environmental toxin. In addition, NiCd batteries are particularly vulnerable to the infamous “memory effect, have a low energy density and high self-discharge.
NickelMetal hydride (NiMH) batteries are the successors of NiCd batteries. They know only a faint memory effect (sometimes called Lazy-battery effect) and have a higher energy density. Positive is the absence of highly toxic metals. But he tolerates less charge cycles than NiCad battery. This must not necessarily make noticeable: even with daily use of inspiron 1520 battery can last several hundred charge cycles to three years

The Lithium-Ion (Li-Ion) has low self-discharge and high energy density. It can store more energy at the same size as the older NiCd and NiMH sony vgp-bps5 battery. Also from the memory effect, he is spared, making it easy to maintain. The high energy density has a price: The Li-Ion battery is more expensive than its predecessor. To create it also makes the decay by oxidation. Its capacity increases so dramatically already after two to three years – even if it is not used
The Lithium-ion polymer battery (Li-ion Poly) is a relatively new product. Unlike the Li-ion sony vgp-bps2c battery it uses no liquid electrolyte. This eliminates the metal to protect the stable housing. The advantage is that freer designs and lighter batteries. Otherwise it corresponds to the Li-Ion battery.
Before we tell you on the next pages as you use your Ibm thinkpad t61 battery optimally, and extend their life span, we also cast the next page a look into the future.
