! Improve the life and performanc e of laptop batteries
Reduce the operating temperature can increase laptop battery life
The battery in your notebook PC is designed to provide the necessary amount of energy for the processor while maintaining HP high safety standards. As a result, the battery may not charge or may stop providing power to the notebook when the battery temperature exceeds the specified, design safety level.
If the notebook battery life appears shorter than normal, the battery stops charging before it is 99%-100% full and the battery appears warmer than usual, the battery has most likely reached its designed “no charge” safety state. The battery will no longer charge until the temperature condition is corrected.
Try one of the following methods to correct the battery temperature:
- When charging the Acer BTP-APJ1 Laptop Battery, do not use applications that require large amounts of system resources such as graphic or memory intensive applications, heavy and extended hard drive usage.
- Turn off your notebook and remove the battery to allow it to return to a safe operating temperature.
- Make sure the notebook PC is operating on a hard surface. Using the Notebook PC on a bed or sofa may block the vents causing the notebook PC to heat up and shut down.
By taking these steps, the battery will return to its normal operating temperature range and continue to charge and discharge as designed.
Calibrating the battery while PC not in use
Recalibrating the battery requires a cycle of a complete charge and a complete discharge. To recalibrate the battery while using the PC is not is use complete the following steps.
The recalibration may take 1-5 hours depending on the age of the TravelMate 3273WXMi Laptop Battery and the configuration of the notebook PC you own. The PC should not be used while you perform the following steps. Completing all the following steps will also calibrate the battery so that the power meter readings are accurate
- Shut down the notebook PC
- Connect the AC Adapter to the notebook PC and to an electrical socket.
- Charge the Notebook PC until the Battery Charge light is Green. This indicates the battery is completely charged.
- Press and release the Power Button to start the computer.
- Press the F8 key several times when the HP Logo displays.
- When the Windows Advanced Startup Menu displays, select the Startup in Safe Mode option.
- Remove the AC power adapter from the notebook PC.
- Allow the battery to discharge completely until the notebook PC turns off.
- The battery is now calibrated and the battery level reading on the power meter is now accurate.
If you are not using the notebook regularly then please unplug the AC adapter and shut down the notebook. By following these practices will improve the life and performance of the notebook batteries. Here is a quick list of Do’s and Don’ts for the care of your Li-On batteries:
- When you receive a new Notebook or Tablet PC, leave the battery to fully charge overnight.
- Condition a new battery by using it until it is fully discharged, and then re-charge it fully. Doing this once a month will help to accurately calibrate your battery.
- Always ensure the battery is recharged as soon as possible after it becomes fully discharged. A battery will be permanently damaged if left for an extended length of time in a fully discharged state.
- Remember that a Lithium-Ion laptop battery will slowly deteriorate; a new battery will always perform better than one that is 6-months old.
- Remember that the battery half-life is rated for a certain total number of charge/discharge cycles (see your User Manual or Quick Start Guide for the rating). For example, a battery that is rated for 3 hours and 500 charge/discharge cycles, will still be considered as within specification, even if it only lasts for 1 hour 45 minutes after 500 charge/discharge cycles.
- Heat is the worst enemy of a battery. Allow plenty of air to circulate around the Notebook/Tablet PC, so that the battery is kept as cool as possible when charging and also when in use. If provided, use the integrated ‘legs’ under the Notebook to raise the notebook and improve air circulation.
- Remove the battery if storing for several months (the battery should be at approximately 50% charge or higher).
- If you use a NoteBus or if charging your Notebooks or Tablet PCs in a confined space, allow for adequate ventilation in order to keep the batteries as cool as possible.
- Do Not – Expose the HP 446506-001 Laptop Battery to excessive heat or cold (i.e. outside the range of 10-35 degrees Centigrade ambient).
- Do Not – Store the battery in a fully charged state (store batteries with about 50% charge).
- Do Not – Allow a nearly flat battery to be unused for more than a month or so. The battery will slowly discharge until it becomes fully discharged and this will permanently damage the battery cells.
- Do Not – Charge your Notebook/Tablet PC inside a carry case – the battery may overheat.
- Do Not – Charge your Notebook/Tablet PC when stacked on top of each other – the battery may overheat.
Remember: Your battery is slowly degrading all the time, even if it is not used. Keeping your battery as cool as possible will slow down this degradation considerably.
