What is a Nickel Metal Hydride Battery (NiMH)?
uses Nickel and other rare earth metals as its electrodes and Potassium Hydroxide as the electrolyte. These are constructed from non-toxic metals making it environmentally friendly. These batteries do not suffer from the memory effect and has a higher capacity than NiCd batteries. However, the NiMH battery has a much shorter life span than NiCd and Li-Ion batteries.
How do I identify my battery?
There is usually a label on the battery, and some of this information on the label will help you identify your battery. Many have part numbers printed, which are unique to your battery. The label may also include the voltage of the battery pack ...
What is a Lithium Ion Laptop Battery (Li-Ion)?
Lithium Ion batteries use Lithium Oxide and a Carbon compound, usually Graphite as the electrodes. These are separated by a micro-porous film containing an organic solvent as the electrolyte. Compared to NiCd and NiMH batteries, Li-Ion batteries ...
How long does a Laptop battery last? When should I consider replacing mine?
All rechargeable batteries wear out with time and usage. As time and cumulative use increase, the performance will degrade. For the typical user, noticeable reduction in run time generally will be observed after 18 to 24 months. For a power user, ...
How should I choose between two batteries with different Watt hours (Whr) available?
Higher Watt hours (Whr) on the same system under the same operating conditions will generally deliver longer battery run time. For example, if you compare the same system, running the same applications, the 53Whr battery would provide approximately ...
What is the "Memory Effect" in Laptop Battery?
Ni-Cad batteries suffer from the "memory effect". As a battery is continually re-charged before being fully discharged, it forgets the capacity that was not discharged. The way to avoid the dreaded "memory effect" is to fully charge and discharge the ...
