Cell Phone Battery Types
The four most common types of batteries for cellular phones are:
Lithium Polymer (Li-Poly)
Lithium Ion (Li-Ion)
Nickel Metal Hydride (NiMH)
Nickel Cadmium (NiCad)
Lithium Polymer (Li-Poly) is the newest and most advanced technology for cellular phone batteries. Li-Poly is ultra-lightweight & does not explode, even when a nail is driven through it! Since the chemistry is enclosed in plastic pouches instead of a metal can, significant weight & form possibilities exist! Manufacturers will soon be molding this type of battery to fit the dead air spaces in some cell phone designs. Lithium Polymer shows all the same advantages of Lithium Ion without the weight or rigid form factors! Li-Poly does not suffer from memory effect, and will deliver up to 40% more battery capacity than the same size of NiMH battery. (Excellent)
Lithium Ion (Li-Ion) is an advanced technology for cellular phone batteries. Li-Ion does not suffer from memory effect and will deliver up to 40% more battery capacity than the same size of NiMH battery. Li-Ion batteries are slightly lighter than NiMH batteries and also have a longer battery cycle lifetime when compared to NiMH batteries. Unfortunately, Li-Ion batteries are more expensive and not available for older cell phone models. aps-cellular.com carries a complete line of Lithium Ion batteries. (Excellent)
Nickel Metal Hydride (NiMH) batteries are relatively newer technology and also do not suffer from memory effect. Compared to a NiCad battery of equal size, a NiMH battery will run for 30-40% longer on each charge. Also important from a driver’s perspective, NiMH batteries can be 50% recharged in just 15 minutes, and up to 90% in 1 hour using a car charger. The unique NiMH chemistry enables the packing of twice as much energy into a given mass than is possible with NiCads. This can also result in NiMH batteries having up to twice the life span of NiCads. NiMH batteries rank as the "best value" of all cellular phone battery types. Their trouble free service, longer running times and reasonable price has made Nickel Metal Hydride the most popular battery type for cellphones. Additionally, NiMH batteries are made from non-toxic materials and are environmentally friendly. APS-cellular.com carries a complete and extensive line of Nickel Metal Hydride batteries. (Good)
Nickel Cadmium (NiCad) batteries are of older technology and suffer from "memory effect". They must be completely discharged before recharging or damage can occur. This discharge procedure can add extra time to the overall charging process. The memory effect that is inherent in all NiCad batteries reduces the battery's overall capacity, run time, and life span. NiCad batteries are slowly being phased out and replaced by NiMH as the battery of choice by cellphone manufacturers and mobile professionals. Also, the "nickel cadmium" used in NiCad batteries is highly toxic to the environment. Please dispose of NiCad batteries properly.
Standby and Talk Times. Standby and Talk times refer to the timeframe before a cell phone battery should need to be recharged under ideal conditions. Since all manufacturers of Cellular telephones are listing times under ideal situations, these ratings are not an accurate measure of battery performance. You should instead compare ratings measured in milli amp hours (Mah) by all manufacturers, giving you a reliable way to compare battery capacity regardless of chemistry or cell phone model. Times will as vary!
Note: Mah – stands for "milli Amp hours" and is the measurement of a battery’s storage capacity.
APS-cellular.com is pleased to offer our customers superior cell phone batteries. In that regard, we no longer sell NiCad batteries or support NiCad technology. Instead, we offer NiMH replacement batteries for existing NiCad models. Far too many problems and customer complaints are the result of NiCad batteries and their inherent memory effect. In most cases their charge holding capacity becomes greatly diminished, or they burn out and die long before their normal life expectancy. One year expectancy.
How to Maximize the life of your battery. There are
several things you can do to maximize the useful life of your battery. Dirty
battery contacts are the number one source of charging problems. Clean the battery
contacts with either an eraser or use alcohol and a cotton swab from time to
time. Make sure no eraser or cotton is left on the contact points. Don’t leave
your rechargeable batteries dormant for extended periods. Cycle them for a full
charge & discharge every so often. Even if you use AC or DC power most of
the time, try to use the battery periodically to keep it fresh and healthy.
Unplug your battery charger if you are not using your cell phone. Batteries
that sit idle for extended periods of time without charging begin to lose their
ability to hold a charge and will self-discharge, so remember to charge them
again before use. Always store batteries in a cool, dry place away from heat
and metal objects.
Intitial Charge Cycle -- New batteries must be trickle
charged (slow charged) prior to their first use and for the first several uses.
As all of our batteries are new, they are uncharged. All batteries require a
"break-in" period, so don't be alarmed if your battery doesn't hold a full charge
right away. A new battery may show false full charge (voltage) as indicated
on your phone or charger. Also the battery may not power up the phone because
of low voltage.
For the First Three Cycles, please make sure to charge the battery fully and drain it fully before recharging.
This will properly condition the battery and will ensure that it will operate at its maximum capacity.
This is recommended for all cellular phone batteries.
You can discharge most portable phones by unplugging the AC adapter and leaving it turned on until completely discharged.
For NiCad (Nickel Cadmium) batteries: A slow charger works best on Nickel Cadmium batteries.
For all other batteries (Nimh, Li-Ion, Li-Polymer): A rapid charger works best, even though it should charge for 10 to 18 hours slowly initially.
For vibrating batteries: Note that the battery does not vibrate when the phone is connected to or placed in any charging device.
Normal cellphone battery replacement schedual is one year!
Remember to "Take care of your Battery and your Battery will
take care of you."
Proper Battery Disposal. For proper disposal of your old battery, you should return NiCad batteries to Please dispose of NiCad batteries properly. You can also contact the local Department of Household Hazardous Waste in your state. Your local Town Hall or landfill is also a good place to inquire.
