To measure a battery's capacity, use the following methods: Measure the time T it takes to discharge the battery to a certain voltage. Calculate the capacity in amp-hours: Q = I×T. Or: Calculate the capacity in watt-hours: Q = P×T. What is the C rating of a battery? The C rating determines the rate at which the battery discharges.
Now, to calculate battery watt hours, we will need only 2 key metrics: Amp hours (Ah). This is your 100Ah battery, for example. Voltage (V). Most batteries have a 12V voltage. Some bigger batteries can have 24V or even 48V voltage. Fortunately, all batteries will have both Ah capacity and voltage prescribed on the battery itself (or the label).
To check these, you can use an app like BatteryInfoView. This app shows the design capacity and full charge capacity, which help you see if your battery capacity has decreased. Windows has a built-in tool called powercfg. To use it: Open Command Prompt as an administrator.
When it comes to determining the battery capacity of your laptop, one of the most reliable sources of information is the manufacturer’s website. Here’s how you can navigate through the site to find what you need: Start by finding the official website of the laptop’s brand. Look for a section related to product specifications or technical details.
