BatteryMark is a Windows utility for diagnosing laptop accumulators. Similar to Samsung Battery Manager, there are instruments for estimating remaining charge levels. Standard and fast calculation methods are available. The main interface is simple and straightforward. This tool does not require installation.

Calculation process

After running the included executable file you can choose the estimation method. In fast mode the software initiates pi number calculations for applying maximum load to the processor. It measures the amount of time required to lower the battery level by 1 percent. Depending on processed data you are able to estimate how long the laptop will work on the remaining charge.

In standard mode users can monitor the battery without creating artificial loads. This option requires more time to evaluate the accumulator condition. Results depend on usage intensity during the testing.

Discharge graph

You are able to visually display battery information. The amount of remaining charge is shown as a percentage. This functionality is helpful for evaluating current accumulator condition and charge levels.
