Battery charging


Hi Patrick,
A rechargeable battery will eventually fail to accept a charge - just like your car battery.
The number of recharges a battery will be able to accept is dependent on a number of things, such as: temperature, if it is run to almost nothing before recharging (or if it is recharged after only being discharged slightly), how much of a load is on the battery and how fast (high amperage) or slow (low amperage) the battery is recharged.
Generally, cooler temperatures are better for batteries, as is using the battery almost completely before recharging rather than topping off after minimal usage, small loads are better (you don't have a choice in your GPS watch tho) and a slow or "trickle" charge is better than a fast, high current charge (you may not have a choice on this either). A few hundred discharge / recharge cycles is not uncommon - significantly less if the battery isn't cycled properly or used in harsh conditions.
I hope this helps!

If the laptop battery is more than 3 - 4 years old then the battery could be worn out. Rechargeable batteries have a finite number of charge and discharge cycles and will lose their charge capacity over time, i.e. won't charge to 100% and gradually the charge reduces until the battery won't charge up at all. OR The battery shows a 100% charge but when the adapter is disconnected the battery drops off to zero capacity in a very short time. If the battery drops to an unacceptable charge level then the battery needs to be replaced.
Rechargeable batteries will fail if stored in a discharged state for long periods.

If you are looking for Drivers then I would recommend an Automatic Driver Download Tool that can detect all your installed hardware, search, download and install all the required latest model and manufacturer specific drivers automatically.

Regarding the Battery, some intelligent batteries remember the charge. If the first time you do not let it discharge completely, then it remembers that setting and never charges more than that. So just try discharging your batteries to zero percent and try recharging it. I am sure it will charge to 100% this time. Read more at www.fixpcfreeze.com

Help on extending the battery life of my acer aspire one!


If the laptop battery is more than 3 - 4 years old then the battery could be worn out. Rechargeable batteries have a finite number of charge and discharge cycles and will lose their charge capacity over time, until they won't charge up at all.
The only solution is a new battery.

Yuasa np7-12 batterty has discharged after 7 yrs. Can I recharge using a std 12 v trickle charger?


Your Yuasa battery is of the sealed lead/acid type. These batteries are meant to be trickle charged at a voltage between 13.2 volts dc to 13.8. If the battery is dead it could take up to one day to completely recharge it. However, you mention it is 7 years old. The life of these batteries is generally 4-5 years. Their rated capacity (7 amp hour when new) diminishes over time. So there is a good possibility that your battery is getting too old to keep a charge and needs to be replaced.

Aspire zg5 battery won't charge


Memory effect, also known as lazy battery effect or battery memory, is an effect observed in nickel cadmium rechargeable batteries that causes them to hold less charge. It describes one very specific situation in which certain NiCd batteries gradually lose their maximum energy capacity if they are repeatedly recharged after being only partially discharged. The battery appears to "remember" the smaller capacity.

This may be why.

Acer 5315 Battery cHarging Problems


All rechargeable batteries have a limited life, and as they age their charge capacity reduces over time and you get shorter and shorter time between charges.
Recharage batteries have a finite number of charge and discharge cycles and batteries over 2 years old are considered nearly worn out. Worn out batteries won't charge up at all.
