Although batteries are a fungible component that have an expiry date, and we will have to replace. It is possible to extend their useful life with a series of care and maintenance, especially in its operating temperature. Or calibrating laptop battery to maximize c​harge cycles and delay the loss of original capacity.

How to check a notebook battery

Checking the condition of the battery is the best place to start caring for it. The industry offers a series of tools that allow us to know its power, load, voltages and ultimately its state of health.

BatteryInfoView

A utility without visual frills but free and informative of the essential values. The results can be exported to a text file that acts as a permanent record of your performance.

BatteryMon

More focused on monitoring, it controls a laptop's battery capacity and discharge rate and presents results in a real-time graph.

BatteryCare

Another free, informative and specialized tool to perform calibrations, one of the recommended functions to be performed from time to time and for which developers report in detail.

BatteryBar

It is a much more complete toolbar utility than the one available in the operating system. It reports the most important information without taking up too much space and resources. It has a free basic version and a "Pro" of 4 dollars.

Powercfg

For the Windows console there is a powerful command available that also gives us information without the need to install additional applications. We access the command line running "cmd" (Windows + R hotkey) and type "powercfg /batteryreport" to generate a report in html version that we can access in the path C:\Users\your username\battery-report.html. The command can be used with the -energy modifier to evaluate energy efficiency and compile the energy settings used.

And remember. There are no miracles, when the battery says enough is enough, we will have to replace it. At the very least, try to delay the moment as much as possible and also the loss of charge that starts from day one if you don't do the proper maintenance.
