Prevent Loss in Battery Power

The life cycle of a HP Pavilion dm4 battery is defined as the number of times you can charge your battery to more than 80 percent of its original, maximum capacity. According to Electropaedia, the normal lifetime of a battery is 500 to 1,200 cycles. The more you use and recharge your battery, the more the battery's capacity will reduce. The loss of battery power is a gradual process. The battery eventually will hold only hold 80 percent of its original capacity, and slowly decline to 60 percent or less, until it no longer works at all. Physical and chemical changes prevent batteries from lasting forever. To get the most out of your batteries' life cycles, follow several steps.

Instructions
1
Keep lithium-ion batteries cool. Heat strains the battery and reduces its power level. According to Electropaedia, "Chemical reactions internal to the battery are driven either by voltage or temperature." When the battery is hot, the internal chemical reactions speed up; this increases performance at the expense of decreasing the battery's life. According to the Battery Education website, "At higher temperatures, the self-discharge on all battery chemistries increases ... Once a battery exhibits high self-discharge, little can be done to reverse the effect."

2
Avoid frequently running the battery down to no power. Fully discharging the battery strains it. The Battery University website recommends partially using the battery then recharging it often, especially for lithium-ion (these HP Pavilion dv9500 battery don't have a "memory" to decrease). Short laptop battery life is caused primarily by heat, not charging lengths. Extend your battery's lifespan by not regularly running it down to zero power.

3
Calibrate batteries with their power gauges (for example, the laptop gauge that measures the percentage of power left on the battery). Unless appropriately calibrated, the gauge will lose accuracy with frequent use. Once a month, run the battery down to zero power. This will reset and calibrate the power gauge so you can accurately measure the power usage.

4
Remove and clean your laptop battery when you're connected to an external power source. Wipe the battery and slot space to stop dust and moisture accumulation. This ensures nothing interferes with the distribution of power from the battery.

5
Store a spare lithium-ion battery in a sealed bag in a refrigerator. Don't freeze it, but keep the spare cool while saving it for when your primary battery no longer effectively works.

6
Ensure your charger is approved for use with your battery. If the charger operates at an inappropriate charge rate or sends the wrong voltage, it can decrease the battery's lifespan. According to Electropaedia, keep the HP Pavilion g6 battery cells "within their desired operating limits during both charging and discharging."
