How long will my battery last?

Your laptop batteries will deteriorate over time whether you use it or not. Although the Li-Ion industry does not publicize this fact, your laptop battery’s clock began ticking the moment it was assembled. The elements inside your laptop batteries slowly react with each other, eventually rendering the battery unable to supply the required power to your notebook. In addition, your laptop batteries are rated to last between 300 and 800 charge/recharge cycles. It will gradually lose charge capacity rather than abruptly fail to power your notebook.

The general consensus is that laptop batteries last one to three years. While you can slow the laptop battery’s aging and loss of capacity, you cannot stop either decline. The temperature of the battery, combined with the amount and nature of its usage contribute significantly to your battery’s lifespan. You can ease the aging process with some care and maintenance.

Temperature Lower temperatures slow down the self-discharge (loss of charge while disconnected) and aging process of the elements within your laptop batteries. Therefore it follows that higher temperatures shorten the life of your laptop batteries. Leaving your battery connected while on AC power causes the internal temperature of the battery to rise. Removing your laptop batteries and storing it in a cool, dry place will help to slow the aging process. Keeping your notebook in a hot environment is also detrimental to your battery.

Amount of Usage The Lithium-Ion batteries used in notebooks are rated to handle between 300 and 800 charge/discharge cycles. Some of these cycles are used when you leave your laptop batteries connected to your notebook while on AC power. On AC power, the notebook will routinely “top-off” the battery when its charge reaches predetermined levels (i.e. 95%). Removing your laptop batteries and storing it in a cool, dry place will help to preserve some of these cycles.

Nature of Usage Li-Ion batteries do not suffer from the memory-effect (requiring complete discharge before recharging to avoid loss of capacity) like older rechargeable batteries. Regular full discharge/recharge cycles result in an increased loss of capacity per cycle. A series of partial discharge cycles are better for Li-Ion batteries than a single full discharge. You should, however, calibrate your laptop batteries routinely. Tell No One You Can Save up to 35%

new battery HP g61 is fully charged but not working \


Maybe the AC Adapter Power Cord is not working. If you can't get on the laptop with the power cord then it is bad and the battery might be drained so you have no power source to power up the laptop.
If the laptop works only off the Power Cord and the batteryis not charging, then the battery is dead.

To check to make sure the Power Cord is working remove the battery and let thelatop run for 10 minutes or so.

To check to see if the battery has any charge left in it put the battery in andremove the power cord. If it won't boot or shuts down then the battery is deadand needs to be replaced if the power cord is ok.
