How to extend your Sony PCGA-BP71 Laptop Battery life?
25 Dec 2009
laptop battery seem to be fond easily these days. We can find them in our laptops. We all want to make our batteries last as long as possible, and how can we extend our laptop batteries.I find some useful advices from articles.

The first: Battery Memory - When I first got my notebook, my friend recommended to fully drain the battery before recharging it. His reasoning was connected to the idea of battery memory. allowing the battery to fully discharge then recharging to max, supposedly gives you the complete battery capacity. Otherwise, if you simply charged from the half way point to max battery capacity, the battery would treat the half way point as the empty point, thus cutting your battery capacity in half. The good news is today’s laptop batteries have a safety circuit in place to insure the battery doesn’t reach the point of no return. The safety circuit isn’t fool proof of course, if you leave your battery completely drained for a few days, even the circuit’s protective measures won’t save it.

The second: Battery Calibrating - There is some benefits to fully discharging your laptop battery PCGA-BP71 periodically, this can be especially important. If you start to notice your battery meter is becoming more and more inaccurate, it may be time for some battery calibration. By allowing your batteries to fully drain, this will help the battery recalibrate allowing for more accurate measurements of battery life. This should be done once every 30 charges or when you notice battery readings are off.

The third: Consequences of Heat - another enemy of battery life is heat. If you were to leave your laptop plugged in and running for a year, you should expect the PCGA-BP71 battery capacity to be anywhere between 60% to 80% of it’s original max capacity. This is why people that use their laptops as desktop replacements will notice greatly reduced battery life performance after one year of use. This issue can be resolved by removing the battery while using a corded power source. Now you may want to check with your manufacturer ahead of time to check for safety concerns, some manufacturers have mentioned problems such as moisture and dust collecting in the battery casing.

The fouth: Battery Storage - If you plan on not using the battery for prolonged periods of time, then you’ll want to have the charge level at 40% and place the battery in the fridge (not freezer). Storing the battery at 100% charge level applies unnecessary stress and can cause internal corrosion. On the other hand, if the charge is too low, the PCGA-BP71 battery can become permanently unusable, due to battery self discharge. This is why manufacturers recommend storing your battery at 40% charge, rather than either extreme .
