How long should a laptop battery hold a charge?

15 years ago

This Acer I've had since Dec '09 seemingly used to hold up for 2 hours; lately it's been around one, even though it is charged completely. I guess they can wear out. If I were to buy a replacement would that make a difference? Thanks for any help!

Yes, eventually they do wear out. Much depends on the rating of the battery in amp hours. A replacement should help, especially if you buy one with a higher rating (if available for your Acer model).

Laptop Recalibration

As a laptop gets older, it starts to slow down a little. You may notice that pages load slower, videos take longer to start playing, and general slowness of the machine. Unfortunately, thousands of people a year replace their laptop batteries without performing any monthly recalibration on it at all. If you want to get the best performance out of your laptop, here are a few steps to follow.

- Charge your laptop's battery all the way to 100%.

-Once the laptop is fully charged, unplug it and let the battery drain. Feel free to use the laptop during this period, as it will help it drain more quickly. Once you see that the battery is almost empty, save your work and close any open pages. Then let the laptop shut itself off.

-Let the dead battery sit for about 5 or 6 hours, or overnight. This will help eliminate any leftover charge the battery may have, and lets the battery start over from zero.

-After you've let your laptop sit, plug it back in and let it charge all the way to 100% before using it again.

Battery maintenance is an important process that many people neglect. Recalibration should be done monthly if possible to ensure best results. If done on a regular basis, you should notice greatly extended battery life on your computer, and hopefully postpone the purchase of any replacement parts.

Hi debi, I was told that you should let the battery completely discharge through use from time to time. Here's some information which says you should do exactly that - but ... I've also been told that that is not necessarily the case so it seems that opinions differ : 'Permanent capacity loss is greatest at elevated temperatures with the battery voltage maintained at 4.2V (fully charged). For maximum storage life, batteries should be stored with a 40 percent charge (3.6V) at 40Â°F (refrigerator). Perhaps one of the worst locations for a Li-ion battery is in a laptop computer when used daily on a desktop with the charger connected. Laptops and portable devices typically run warm or even hot, raising the battery temperature, and the charger is maintaining the battery near 100 percent charge. Both of these conditions shorten battery life, which could be as short as 6 months to a year. If possible, remove the battery and use the AC adapter for powering the laptop when the computer is used on a desktop. A properly cared for laptop battery can have a service life of two to four years, or more.' This info was obtained through link below if you are interested.

Read your manual. It probably has the guidelines best suited for 'your laptops design and its circuitry . Toshiba here was first time ever taken out of the factory box about mid December 2007, so its 1.5 yrs old, I don't know how long it sat on shelf - its battery right now shows a 6% wear level, 44000 mWh design capacity new / currently 41151 mWh at 100% of charge. Probably more than 99 percent of the time its on the AC adapter and runs 24/7. Sleeps after 100 minutes of non use which really doesn't happen every day like I should. I should force sleep for it & then maybe I'd force more normal sleep on me too ;) Battery is under the left palm rest where I feel no heat. It would be rare for me in the things I do to shut down windows before moving the laptop while the on battery. Only have the one ac adapter, meant to buy another for a second location but price always makes me dizzy.

Laptop battery not charging

Several months back I also had problems with my 4 year old HP laptop. The power adapter had to be wiggled for the darn thing to make a connection and keep power flowing to charge the battery and power the laptop. I took it to a shop that specializes in laptops and had it checked out. What was wrong was that where the adapter plugs in at the back was cracked inside from wear and needed to be replaced. The tech took apart the laptop and even showed me where the problem was. The new part had to be sodered (sp) so was not just a simple fix. With labor, parts and having them add another 500mgs of ram (Something I had been wanting to do for a long time.) it cost me around $300 for everything. Cheaper then a new one and works like a charm now. It should last a few more years until I'm ready to upgrade ;o)

how? when? charge my NIMH batteries

It is best to use a charger rated for NiMH batteries, NOT an NiCd charger. The two types of batteries have different charging profiles and the circuitry in the chargers is a little different. As to whether you can charge them all at once, it should not be a problem. Each will charge as far as it needs to and the charger will stop there. NiMH batteries have less of a memory problem, so charging them when they aren't completely dead does not reduce their lifetime like it does with NiCds. Finally, your volt meter will not really tell you how much charge each one has, since it reads voltage and not current output capability. Voltage stays almost constant until the battery is about dead. The first one on your list is about totally discharged. The other ones could be at 80, 60, or 20%, hard to tell from a voltage reading.

When they say a battery is good for x number of hours, it depends upon what you are doing and how bright you have the monitor etc set while on battery...if doing something high intensity and full brightness, the battery will not last that long...if playing solitare on a dimmed monitor, it will last a heck of a lot longer...as mentioned re-calibration sometimes helps and if replacing the battery, see about a replacment with more cells..maybe mention what model you have a we could help
