Mobile Phone Batteries. What Are Your Options?

There are a range of some mobile phone, video camera/camcorder and digital camera batteries out there with varied
capacities and battery chemistry. We wish explain what the differences are for each battery chemistry and try to clean up the jargon used on the labels of mobile phone batteries. There have been some developments in battery technology and below, we wish outline each battery chemistry's features, pros and cons and their applications to mobile phones today.
"Memory Effect" in Batteries
Memory affect refers to the need for certain batteries to be "serviced" by on a regular basis
discharging the battery all before recharging. Ni-Cad batteries are the main type of battery chemistry that requires this athletics
and newer types of batteries such as Li-Ion and NiMH do not suffer from memory affect.
Battery Capacity Ratings
A battery capacity rank refers to the load or current that can be placed on a specific battery type. The battery capacity rank is commonly measured in milliampres (mAH)
Ni-Cad (Nickel Cadmium) Batteries
In the past, majority of rechargable batteries used in portable devices such as mobile phones, camcorders and conductor
phones used Nickel Atomic number 48 as the main battery chemistry. Tho'
this type of battery has drawbacks such as the "memory effect", it is still one of the most ordinarily used battery in conductor
phones, CD players, Radios and different portable devices due to their low cost per battery cycle. The use of these batteries in mobile phones now is rare due to their memory effect problems and inconveniences. Despite these obvious drawbacks, it as well has environmental implications due to the metal used to manufacture these batteries and are fast becoming replaced by Nickel Metal Binary compound
Batteries.
NiMH (Nickel Metal Hydride) Batteries
NiMH batteries are one of the growing battery chemistries now in the main due to the fact that it does not suffer from memory effects like a Accumulator battery does. Because of this advantage, they are in the main used in Laptops and mobile phones and sometimes as well as a battery source for video cameras and digital cameras. This is an important and main feature that does NiMH batteries attractive as consumers are not burdened by having to "service" their batteries by discharging it fully before recharging. They as well have a higher capacity rank compared to Ni-Cad (approx 30% higher) and Alkalescent batteries, however their main disadvantage
is that these batteries self-discharge over a short period of time which does them not suitable for storage.
Li-Ion (Lithium-Ion) Batteries
These batteries are quite new to the market and have the lowest discharge rank compared to Ni-Cad and NiMH batteries. They do not suffer from memory effect and is one of the most ordinarily used type of batteries in mobile phones today. They have an fantabulous power to weight quantitative relation
which does them extremely
attractive to portable devices such as mobile phones, video cameras and digital cameras. All our mobile phone batteries we offer are Li-Ion as they are superior compared to different battery alternatives.
Li-Polymer
This is comparatively
new and we are beginning to see much of these batteries appear in mobile phones today. They are considered as the better battery chemistry now for mobile devices due to their high capacity and low weight. Li-Polymer batteries do not suffer from “memory loss”.
