ThinkPad batteries are a "consumable product" that reduces performance over time. However, if you follow the instructions below, it will greatly extend the life and performance of your battery.
1. If the battery has not been charged for a long time, or is not connected to the ThinkPad at all, it will cause the next charging time to be lengthened.
2. Please use the correct ThinkPad power adapter. Using a mismatched power adapter will prevent the battery from being fully charged and the battery information will be displayed incorrectly (Appendix 1)
3. Re-construct your battery every month - that is, keep your battery below 3%, which will increase your battery capacity (attached 2)
4. If you mainly use AC power, only occasionally use the battery, you can change the battery charge threshold to improve your battery life (attached 3)
5. When your computer performs high-intensity calculations, the temperature of the battery and system may increase. In this case, the battery may automatically stop charging to ensure that the performance and life of the battery are not lost. Once the battery stops charging, the battery will only recharge after it has dropped to the specified temperature, and will not charge immediately after you plug in the AC power (and the charging time may be extended)
6. Do not use the ThinkPad or battery in high temperature environments. For example, in a hot weather car
7. In a cold environment, the performance of the battery will temporarily decrease.
8. When the battery and the ThinkPad are separated and stored for a long time, please reduce the battery power to less than 50%.
9. Please use Battery MaxiMiser software to improve battery performance and life.
10. How to check the battery charging times?
Install all the drivers and the Battery MaxiMiser ThinkPad Co nfiguration software, then open the Control Panel Co ntrol Panel
→Thinkpad Co nfiguration →Power Management →Battery Information →Status
Detail →Cycle Count
To see how many times you charge, click on Start, select the ThinkPad Utilities option in the program, select BATTERY INFORMATION, and click on the Stutas Detail page, where Cycle Count
Appendix 1 Natural Consumption of the Battery In normal use, the ThinkPad battery capacity changes with time as shown in the figure below (the abscissa is the year). The battery usage depends on the number of times the battery is charged. One charge means that the battery is charged more than 85%. ThinkPad's battery health testing tool uses battery design capacity, actual capacity and number of charging times to determine battery health.
The ThinkPad's power adapters are available in 56W and 72W. Using the wrong power adapter can result in insufficient power for the battery and less battery capacity.
Appendix 2 Deep Discharge Occasionally, you may need a deep discharge (1-3 times) to improve the performance of your battery. This requires 100% battery usage and then 100% charging, and we recommend that you charge all night (丫丫 Tip: 8-12 hours) without using the ThinkPad during this time. The new battery also needs to be charged overnight before use.
The specific method is: Click on Improve Battery Health—>Reco ndition Battery Now
Appendix 3 About Charge Thresholds If you are primarily using AC power and only occasionally use the battery, you can increase the battery life by changing the charge threshold.
Change the charge threshold, specifically to reduce the initial charge percentage of the battery (default 96%), or to reduce the percentage of battery termination charge (default 100%, but the battery that is not used often should reduce the existing power instead of 100% charge, so Can extend battery life), thereby reducing battery charging times and extending battery life.
a. The charge threshold setting is only valid if the Battery MaxiMiser is running.
b. The charge termination percentage is at least 4% higher than the charge start percentage
c. Due to the aging of the battery, the charging threshold is generally set 2% higher than the ideal value.
d. When the charge stop percentage is less than 100%, please charge the battery 100% every three months.
