Before continuing with my post, I must admit that this may not be the appropriate forum for posting this topic, however, I couldn't find one that's why posting it here.

There are four types of batteries available for mobile phones:

Nickel Cadmium (NiCd)
These are least expensive of rechargable batteries, but suffer from inherent shortcomings like memory effect. Here, if the battery is not fully drained before recharging, the unused portion crystallizes hence the complete capacity of the battery is not fully used.

Nickel Metal Hydride (NiMH)
This technology offers 30 to 40 percent longer operation as compared to NiCd batteries but it is susceptible to loss of performance at higher temperatures.

Lithium Ion (Li-ion)
The prime advantage of these batteries over NiMH are that they hold more energy for same weight and volume. Therefore, Li-ion batteries are much smaller and thinner in comparison. Also, they don't have any inherent memory effect. The only disadvantage is that they cost more than others.

Lithium Ion Polymer (Li-Po)
Li-Po batteries are rechargable batteries that have evolved technologically from Li-ion batteries. A significant advantage of these batteries is that manufacturers can shape the battery almost however they please, which is very important to mobile phone manufacturers constantly working on smaller, thinner, and lighter phones. Many latest phones, PDAs use these types of batteries.

Steps for longer battery life
In case the mobile phone uses NiCd or NiMH batteries, let them get discharged completely before you recharge them

* Check that phone's battery contacts are clean
* Keep the batteries in cool, dry place, away from heat and magnetic objects
* Don't leave the batteries dormant over an extended period of time.
* Switch of features such as Bluetooth and Wi-Fi when not in use
* Many mobile phones allows to customize the brightness and contrast of LCD screen. Setting these values low will prolong battery-life
* Keeping the sound level for ringtones and other audio notifications at low will help you increase time your battery lasts.
* Do not expose battery at extreme temperatures.
* Do not overcharge battery
* Use battery chargers specified by the manufacturer only.

Nice topic! I learnt about my lithium-ion battery and I found out things I didn't know!
Not many people will start a thread like this, but this is an interesting one!

Ups Battery Backup - (11)

I'm currently using a regular power surge protector for my computers. I have been thinking of
buying a UPS battery backup instead. Is there any big advantage over having a regular surge
protector? I mean, if I do get a surge, will the UPS backup still be in good condition for me to
shut my computer down properly? Most of the lower end UPS backups I've seen say the power run
time is 4-10 minutes long. Why does it take 4-8 hours to charge it up to 90% and give so little
power usage at the end? What should I look for in terms of joules, VA, and other terms I see be...

Laptop Battery Bay Damaged? - (15)

I had my laptop for over a year and suddenly one day it won't hold the charge in the battery
anymore. So I thought it was a bad battery...sent it in to be repaired and the techs said it's
not the battery. Tested ok. They said it was the charging port. Warranty was over already so I dealt
with the issue...about 3 years now. I want to know how to repair this. Do I have to change the whole
motherboard to replace that battery compartment area? Or is there an easier way to do this? The
laptop is a Prostar 6194. Thanks....

purchased a regular supply for my current computer as a replacement a while back and it had all the

I'm not 100% sure that it will work with this mobo. Some says it does, some say not! If it
works, the oc'ing is extreme and really worth it. 3200+, just by changing the FSB, and this with
low temp! Anyway I would like to hear about your experiences. Good or bad, preferably with this mobo
but also in other combinations. cheers Edit If anyone would be interested I...
