If you have a volt meter you can check the battery voltage, and also the voltage of the charger. If the batteries are nicads expect 1.2 volts per cell if they are the AA or AAA size, 1.5 volts for the nickel metal hydride cells. the voltage of the charger should be equal to the total voltage of the batteries it is chargeing.

How to Help HP Pavilion Laptop Power Battery Using Problems

Hp laptop users might experience that the battery is overheated, or the laptop battery suddenly stop charging. Sometimes, the battery health "good" but the battery does not hold a charge, etc. So, how to fix these problems?
First of all, you know that the most common type of AC power adapter involves a small box, with one wire to go to the computer and another wire to go to the wall. There is usually an LED light on it, to tell you that it is on. When your laptop doesn't work, you need to troubleshoot the AC power supply, system board and the battery are functioning correctly. The battery is an important part. It supplys power to the input-side of the voltage regulators, just like the power from the AC adapter. Additionally, there is a charging circuit, which uses the power from the AC adapter prior to the voltage regulators, to charge the battery. (By the way, this is why the AC adapter voltage is always rated higher than the battery's rated volatge-- you need higher voltage for charging.)
Verify the Hp laptop battery like this:
1. Insert the battery into the battery compartment on the bottom of the notebook PC.
2. Connect the AC power supply and allow the battery to charge for 15 to 30 minutes.
NOTE: The power LED, located near the power icon (displayed as a lightening bolt on most PCs) , should glow while the battery is charging.
3. Unplug the AC power adapter cord from the notebook PC.
4. Press and release the Power button to start the computer using only the battery as the power source.
If the PC does not power on, then the battery needs to be replaced. Contact HP service and support for further assistance.
If the notebook PC does power on, the battery is functioning, however you should run the HP Battery Check utility to evaluate the battery's health.
NOTE: If you have purchased a second battery for your notebook PC or you have access to an identical battery, you can also check the battery by inserting the second battery into the PC and performing the Troubleshoot the battery steps again.
Your new HP laptop battery comes in a discharged condition and must be charged before use (refer to your computer manual for charging instructions). Upon initial use (or after a prolonged storage period) the battery may require two to three charge/discharge cycles before achieving maximum capacity. When charging HP laptop battery replacement for the first time your computer may indicate that charging is complete after just 10 or 15 minutes. This is a normal phenomenon with rechargeable batteries. Simply remove the battery from the computer and repeat the charging procedure.
It is important to condition (fully discharge and then fully charge) HP replacement laptop battery every two to three weeks. Failure to do so may significantly shorten the battery's life (this does not apply to Li-ion batteries, which do not require conditioning). To discharge, simply run your device under the battery's power until it shuts down or until you get a low battery warning. Then recharge the battery as instructed in your user's manual. If replacement HP laptop battery will not be in use for a month or longer, it is recommended that it be removed from the device and stored in a cool, dry, clean place. It is normal for HP laptop replacement battery to become warm during charging and discharging.

Battery runs down after about 10 mins

The battery may actually be charged 100% when you start reading but after a year of charging and discharging it may need to be replaced, especially if it is a NiCd type.

While im driving i noticed the amp meter was going down to the left(discharge). I would turn off all electrical acc and then after 10-15 secs. it would jump back to a normal position on the guage. I...

I suggest that you check your charging system. With the ignition off, measure the battery voltage, then measure it again with the engine running. The voltage should be higher with the engine running, by 1 - 2 volts. This is a just a quick check, but if the charging system isn't working at all, the voltage will not increase when the engine is running.

now hold the positve wire to the +ve of the batter and negative wire to the - ve of the battery (BE SURE OF THE POLARITIES esle u'll destoy the batery completly) and hold it for not more than 10-15 secs and then quickly place for charging in the battery charger

THE battery MUST be charged with the correct charger. Assuming that is the case new batteries need to be cycled a few times before they come good...Also you MUST use the exact same spec battery in mAH. if you are using ni-cads they need to be fully discharged to a safe low level before recharging as they suffer from memory type the need to be charge cycled a few times before they come good. There are problems with all types of rechargable batteries...Makers have still not reached perfection..never leave a radio always connected
to the ac line , this will stagnate the battery/cells causing problems you must use your device on battery power in order to cycle the same. This is the main reason why laptop batteries have a short life.
