Lithium-Ion laptop battery is no exception for batteries lifespan

Is your laptop starting to feel more like a desktop, constantly needing to be plugged in and recharged? This is a classic sign of capacity loss, where batteries become increasingly unable to carry a charge. Unfortunately, battery degradation is unavoidable. All batteries have a lifespan, and with a life expectancy of 2-4 years, the Lithium-Ion laptop battery is no exception. Fortunately, there are several steps you can take to slow the degradation process.
1. Avoid Excessive Heat
This is quite possibly THE most important factor that will influence how long your Dell latitude d820 batteryDell vostro 1510 battery lasts. All manufacturers agree that it’s extremely essential to avoid excessive heat, which destroys the battery’s effectiveness. Apple recommends keeping your acer battery between 50F-95F when in use, with room temperature 70 F being ideal.
To keep your laptop–and its battery–within the recommended temperature range, use it on a flat surface that allows air to flow from the vents underneath. A cooling station is a great way to keep air circulating. You can get one for as little as $10 on Amazon. It’s best to keep your laptop off of bedding comforters, pillows, and clothing, these materials not only collect heat, but also prevent your computer from ventilating.
2. “When using wall current, is it OK to keep the battery in the laptop?” It depends.
Shoppers frequently ask if it’s okay leave the toshiba battery in your computer if it is plugged-in most of the time. This is a highly debated issue and there is a lot of inconsistent information on the web, even amongst manufacturers! Apple says you shouldn’t leave it in while Dell says it doesn’t matter. After examining the data out there, I’ve concluded that it depends on your computer usage habits.

You should remove your battery if your computer is ALWAYS connected to an external power source and frequently runs programs that require a lot of computing power (e.g. games, video editing software). Under these circumstances, there is usually a lot of heat coming from the laptop itself. If your battery is always next to this heat source, it will degrade quickly. This goes back to tip #1 above–avoid excessive heat.
According to BatteryUniversity.com, 40% capacity loss occurs in as little as 3 months if lithium-ion batteries are kept in extremely hot environments–above 140 F–while being fully charged.
If you’re always mobile, you shouldn’t worry about keeping your Dell inspiron 1520 batteriesDell inspiron 6400 battery in your laptop–so long as it doesn’t get too hot. Ideally, it’s best to switch off between external power and battery power to “keep the electrons moving.”*

3. Your Battery Should Calibrated Every Month
The on-screen battery icon, which displays your battery’s current charge level, becomes less accurate over time. You might have experienced this firsthand–I definitely have.
One minute, your battery shows an hour of charge left, but just a few moments later, it’s down to 20 minutes.
Sometimes the battery meter may report a substantial amount of charge remaining, when in fact, the hp battery actually has much less than that. This can cause your laptop to shut down unexpectedly.
Calibrate the battery every month or two to keep the charge meter accurate.

Battery Solution - Battery Plugged in not charging and not detected

I have a Dell Vostro 1510 laptop, and when i have the battery charger plugged in, the battery icon says "10% available (plugged in, not charging)", and if i pull out the cord, the laptop shuts down straight away. Can this be fixed, and if so, how? I bought this laptop new around 6 months ago. The detail info below:
plugged-in-not-charging
The Battery didn't charge or detect being plugged in also caused by four reasons:
  • 1. The Vostro 1510 laptop battery failed
  • 2. The Adapter failed (can not charge the battery)
  • 3. The motherboard charging electric circuit failed (many caused by short damage). You can view more info here: Dell Motherboard Problem
  • 4. The laptop bios is too old to recognize the battery
After I checked my battery and adapter and confirm they are good. Then I try to repair it by myself.. My Latitude d620 battery was fixed by myself.

The first solution :I search in the google: Repairman from another site suggested that while the computer is on and plugged in, to unplug the adapter and then plug it back in again. To check the computer can started charging.
So I remove the laptop battery from the laptop and left the AC cord connected, booting it up on the power cord alone until I was able to boot into Windows 7, at which point I then put the laptop battery back into the computer while it was still on. This worked and while a tad unsafe for most people, I wouldn’t recommend you use this idea unless you absolutely had to, that is, if there was no other choice.http://www.wholesaleeshop.com.au/Laptop/
The Second Solution: You can download the newest BIOS from dell.com and then flash the bios. But I do not want to update Bios, So I use another way to make the Power manager system to recognize my latitude d630 battery.
I open up my laptop Device Manager (usually a right click on your Computer/My Computer) and remove all Dell inspiron 6400 battery related devices from the Device Manager. Then after you’ve done that, right click again and select “Scan for Changes”, which should reinstall the proper services and allow for your laptop to charge again.
If this also can not solve the problem, I suggest you send the laptop to Dell to repair the Laptopmotherboard.
