BATTERY (Li Ion) NOT RECHARGING

Battery (Li Ion) is not recharging. Replaced with a brand new battery. Still no recharge. Batteries run machine when still charged. Machine runs fine on AC power. Must leave unplugged when not in use. Burned out an external power supply, as it was endlessly trying to charge the battery. With directions, diagrams, etc., and parts I am capable of working on the machine. (Journeyman Electronics Mechanic) Please advise.

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% 3323.jpg

How to enlarge your notebook batteries life


Most of our time, the capacity of our notebook battery is not enough for our work and life. If you don’t have money for Apple Macbook , Dell and HP that have acclaimed battery life of 8 hours, this few tips will help to enlarge your notebook battery life a little longer:

1. Use only the power cord that came with your notebook or other authorized replacement.

2. When you don’t use it, follow the correct maintenance for your notebook.

3. Don't leave it in direct sunlight, areas where it will be exposed to extreme temperatures such as car trunks.

4. If your notebook has power management features, use it, so the system will run at lower processor speeds when enabling power management features and it will go into "sleep" mode faster when inactive.

5. Buy notebooks with internal Li-Ion batteries. Non Li-Ion batteries must be fully discharged and recharged every 2-3 weeks.

6. If you don't use your notebook for a period of time, you must fully discharge then recharge it, so the battery will last longer.

Battery will not charge


li-Ion batteries have a bad habit: whenever fully depleted, they lose a few cells, to the extent that they might not be able to hold a full charge if enough cells are damaged. In other words, repeatedly using a laptop (or any other Li-Ion powered device) to battery depletion can shorten the battery's life significantly. You might want to keep the batteries fully charged whenever possible and avoid fully depleting them too often.
There is also the habit of "re-setting" the batteries by using the "fully deplete-fully charge" procedure. It only applies to niMH or NiCD batteries ( and is used to erase the "memory effect" ) but is damaging to Li-Ion batteries for the reason mentioned above.
so if your battery can not full charge,this mean you need change a new battery for your laptop

My computer will not come on, the green lights are on except the one under the battery.


Try taking the battery out and leave the machine hooked up to the AC power and try it again. Li-ion batteries have a built in safety feature to prevent fires if the voltage is too low to safely recharge. If this works then you will have to get a new battery to make the machine portable again.

Will not start up


Take the battery out of it and leave it connected to the AC power and try it. I suspect that your Li-ion battery has gone so far down in it's capacity that it has locked the machine up to prevent the charger from charging the battery. This is a safety feature built into LI-ion battery packs to prevent rapid recharging of a dead battery that may cause a fire in the battery.

DELL LAPTOP INSPIRON 6400 MY LAPTOP BATTERY IS SHOWING STATUS ( UNKNOWN ) ON WINDOWS & ON BIOS IT SAYSS BATTERY NOT INSTALLED


Here are my recommendations for this issue:

1. Reseat the battery.
2. Remove All External Components
3. Check the battery connectors on the battery and the system. Examine the connector on the battery and the system. Make sure that there is no physical damage and that it is clear of debris.
4. Remove All External Components
5. Try a known-good battery in the system, if available.

Battery not recharging


All batteries die sooner or later. I believe you have a dead cell.

1) Find another machine that uses the same battery and try it or
2) try another battery or
3) Give up and buy a new battery.

Good luck.
