The Battery Life Saver™ electronic device will not help a battery or batteries that have an open or shorted cell. In order to tell if a battery as an open or shorted cell, simply perform the following test.
Step 1: Make sure you turn off any instruments or accessories that will drain the battery or battery system during testing.
Step 2: Charge the battery or battery system until it is fully charged .
Step 3: If the system has multiple batteries connected, we recommend to disconnect them from each other to get an accurate reading. Apply a load to the battery or battery system for at least one hour (or let them sit for 8 to 12 hours). This important because if you measure the voltage immediately after charging, you will not be measuring the true voltage of the battery.
Step 4: With a voltmeter, measure the voltage of each individual battery.
Step 5: Reference the chart below to determine if your battery or battery system has a shorted or open cell. For example, if a 6 volt battery is reading below 4.3 volts it has an open or shorted cell and the battery must be replaced.
|Battery||Voltage Reading of Short or Open Cell|
|6 volt||4.3 volts or below|
|8 volt||6.5 volts or below|
|12 volt||10.7 volts or below|
If you have been using the BLS or plan in using one you will only need to replace the bad battery with another used battery (or a new battery if necessary). Now you are ready to start using the BLS… .
