Today we will consider the HRM-10 battery tester from FNIRSI. It can be used to test a car battery, a gel battery, a battery from a power tool and household appliances. The battery with this device will show the internal resistance and voltage at the battery terminals. Checking the battery is not difficult. We can evaluate the condition of the battery with the tester. It can also be used to sort 18650 batteries and other types of batteries.
