3.1.1 Notice before test
For testing batteries of low-frequency use, it is necessary to cycle (charge
and discharge) the battery several times before testing, normally 3-5 times
will achieve a reliable test result. Because only after the cycling of the
battery can the chemical properties of battery be restored, after a long
periods of no use. if after 3-5 times of battery charge and discharge, the
battery health state is still lower than 60%, then battery replacement should
be considered.
1. Low use batteries should be charged once every 1-2 months to extend
the battery life for the vehicle or boat..
2. Please turn off the engine before testing.
3. Even when testing an in vehicle battery, after the engine is turned off (for
the most accurate results) wait 10 minutes before testing.
