Laptop battery has integrated Microcontroller which manages the current and charge limit. Whenever battery is full it will stop charging. When you are using the computer if unit is connected the Outlet it will not consume battery power. So battery will stay unused.

if you are not using computer mobile and electricity has no black out, you may release the battery keep in dry and cool place. this will be 2nd option for you to choose.

Also having latest BIOS update is better for the battery. As BIOS updates includes some power management fixes.

Whenever electricity is accessible I encourage you to use the AC adaptor rather than battery. Because each Charge-Recharge cycle is a step to reduce the battery's life. Technically battery looses its performance after 500 cycles.
Hope it will be helpful

You should charge fully then remove power once it is charged.
use it with battery till battery is discharged.

leaving it plugged in all the time will kill the battery.

thanks for rating.

Is it best to keep my scooter on charge all the time or what


Lead acid or deep cycle gel batteries are best kept on trickle charge.

Take care of your batteries
How do I get the most life out of my new batteries?
To maximise the life of your batteries, it is best to complete a full charge for the first 1015 times that you use your scooter. This simply means however far you travel, do not just top-up for a short while, but complete the full charge cycle every time. Your batteries will not work at their best until this process has been carried out and will prolong power and performance. You will find the distance your scooter can travel will gradually increase over its first few weeks as your batteries reach optimum efficiency.
When is it best to charge my batteries?
After 10-15 cycles have been completed, a normal charging routine can be adopted
  • Depending on the capacity of the batteries, the charge time can vary up to a maximum of 16 hours
  • The charger will automatically shut down when the batteries are fully charged, so you do not have to worry about switching it off. This is ideal for overnight charging.
  • Whenever possible try to avoid interrupting a charge cycle. It is always best to complete a full charge cycle as excessive short term charging is detrimental to battery life.
  • For the very best results and to maximise battery life, charge fully before and after use.
  • Please refer to charger indicator lights for battery status.

How do I store and maintain my batteries?
  • If your scooter will not be used for a while or is being stored, make sure the batteries are fully charged first.
  • If your scooter is not being used, make sure the batteries receive a refresher charge every 14 weeks. Alternatively if you are planning not to use your scooter for over 6 weeks, fully charge your batteries and then disconnect.
  • Fully charge the batteries before re-use.
  • Never leave the batteries in a discharged state.
  • Avoid damp, hot or cold extremes when storing your scooter.
  • Batteries are totally sealed and do not require any maintenance apart from charging.

Charging
1.Switch off your scooter and remove key.
2.Plug charger into scooter charge socket.
3.Push charger plug into wall socket and switch socket on.
4.There will be a light sequence on the charger but as all chargers are different, refer to charger instructions.
5.Most scooters will have an inhibit mode which will shut down all the scooters electrics while the charger is plugged in.
6.Only use the charger supplied with your scooter.
7.Do not smoke or use a ***** flame while batteries are being charged.
8.Do not leave charger plugged into your scooter when the charger is switched off as this may discharge your batteries.
9.For a complete charge do not switch off, unplug or interrupt the charge cycle until it is complete.
It is worth considering that in extreme cold weather the time your batteries take to charge can increase by up to 20%. The range of your scooter will also vary based on weather conditions. Also when your batteries reach the end of their useful life, you will find that charging time will become much shorter. The amount of charge the batteries can hold will become less and less as will your scooter range until ultimately they become unusable.

How to extend the battery life of Razor Scooter Batteries


You can extend the life of your scooter's battery if you take proper care of it. Most people report trouble in getting more than a year or two out of their razor scooter battery set. This is actually a common problem with vehicle batteries.

  • Keep your battery charged
It is recommended to keep your battery fully charged to avoid the build-up of sulfate-ion inside it. Sulfate-ion accumulates when the battery is in a discharged state for a long time.This is the most common reason of premature depletion of lead acid batteries. This can be easily avoided if the scooter battery is kept in a constantly charged state.

  • Charge you Razor Scooter Battery during the Off-Season
Even if not used Sealed Lead Acid Batteries will self discharge over long periods. This will leave the battery in a not fully charges state which will enable the sulfate-ions to build up inside the internal plates which will slowly deplete the battery's capacity. In order to prevent that, you should charge the razor scooter battery at least once every three months when it is not in service.

  • Use a Battery Tender
Battery Tender chargers are a great way extend the life of your SLA batteries as they are designed to fully charge and maintain a battery at proper storage voltage without the damaging effects caused by trickle chargers.

How to increase the life of the laptop battery


Below mentioned are the suggestions that may help you achieve optimum performance from your battery.

1. We all know how wireless activities drain our device’s battery. They consume significant power even when not in use but left ON. So when on battery power, it’s advisable to turn off wi-fi and bluetooth services.
2. Say no to Screensaver: For best battery life, switch off the screensaver.
3. We should reduce the screen brightness to the lowest comfortable level in order to gain some extra battery life.
4. Unwanted Sounds: Try to mute the speakers volume and avoid using multimedia software for better battery life. Also you can avoid sound schemes which are installed which may reduce your battery life.
5. USB devices and other external peripherals should be shut and removed if not in use. For instance, charging an iPod while on battery, unless very essential, is a bad idea. The same goes for removing any CD or DVD when not in use.
6. Whenever our system runs out of RAM memory it uses virtual memory resulting in hard disk use, which is relatively a less efficient option in terms of power consumption. However, it goes without saying that additional ram does consume energy too so this advice suits best those users who often find themselves in need of extensive virtual memory.
7. It’s a good idea to shut down background programs to reduce CPU usage, say for instance desktop search applications.
8. Avoid using the plug-in DVD rom / external drives which generally runs on batteries. You can transfer the content to the hard drive or you can also run virtual drives like Pismo File Mount, Daemon tool or even Microsoft’s Virtual CD ROM Control Panel.
9. Optimize your power options to get maximum battery juice. The notebook should try to shut down the hard disk and put the display to sleep whenever idle.
10. For a healthy lithium based battery, it’s advisable to keep the electrons in motion occasionally. It’s not absolutely healthy to keep it plugged in all the time. Ideally, one should let it discharge fully at least once a month to keep the battery juice flowing.
11. When on battery power, say in a flight, use one application at a time. Ideally shut the email app once you’re done with it and then turn on the word processor.
12. A defragmented disk puts lesser strain on the battery and hard disk, so make your disk drive as efficient as you can by performing defragmentation regularly, say once every month.
13.Hibernating retains your system state as you last left it. So it’s more energy efficient than even shutting down the computer and booting it all over again.

How to extend battery time for i phone?


Ensure any unneeded apps are stopped and not running in the background. Some apps such as facebook / twitter / etc may need to be completely uninstalled or logged out to keep them from running.
Turn down the screen brightness, Generally turning the screens brightness down till it can still be easily seen but not overly bright can increase cell phone battery by up to 20%
Shut off wifi / bluetooth / gps when not required. Disable Wifi / bluetooth, and GPS will also increase your phones battery time.

Ensure a full charge, most devices (iphones included) usually require a minimum of 8 solid hours to charge, even when they say full, they are not actually "FULL". Make sure your device gets at least 8 hours of charge time before use, and don't allow the battery to drain all the way before the next charge.

It keeps freezing and battery wont charge


Usually when the battery doesn't hold a charge anymore (even if you've plugged it in to a power source for quite a long time), the device will not longer work ... i.e. it freezes or shuts down. That's because the GPS uses power from the battery and not from the AC power source (that is plugged in and charging the device).

Not really, the older NiCad batteries get a memory effect if you keep charging from a half charged state, but modern Lithium batteries do not suffer from this problem.
If thelaptop battery is more than 3 - 4 years old then the battery could be worn out.These rechargeable batteries have a finite number of charge and discharge cycles andwill lose their charge capacity over time, i.e. won't charge to 100% andgradually the charge reduces until the battery won't charge up at all. OR Thebattery shows a 100% charge but when the adapter is disconnected the batterydrops off to zero capacity in a very short time. If the battery drops to anunacceptable charge level then the battery needs to be replaced.

Battery life increasingly short


Batteries need to be discharge all the way down prior to charging. If you don't do this the battery has a memory when stage the power of the battery is in. For example if I charge a battery that is only half way discharge and I charged it, from that point on you will only have a have charged battery. When the power goes down to half you no longer have power. So you keep charging it and you end result is what you have, increasingly short life. Good Luck

Batteries are expensive so check to see how much they are versus how much a new purchase will be, and make your decision.

Batteries have a mind of their own!
Turn the laptop on and let it run the battery down completey. Don't worry about losing data as laptops, when set up properly, have a small sector on the hard drive that stores an image of the hard drive in machine code.
Run the battery down, re charge it with the laptop and repeat the routine at least 4 times. This should increase the likelyhood of an extended life of the battery.
When batteries are left charging permanently, they lose their charge life.
Hope this helps.
