Are SLI Batteries Weaker Than Other Designs?

Batteries come in many varieties, including starting, lighting, and ignition (SLI) cells. These batteries are designed to provide enough energy to start vehicles and provide limited backup power for accessories. While these power-cells can be durable, if they completely lose their charges they may develop performance flaws.

In order to prevent this, it is important to regularly check your SLI cell for physical damages and for voltage levels. To gauge the voltage load of your battery, you will need a digital voltmeter.

To begin, turn off your ignition and lights. Then, attach the positive voltmeter probe to the positive battery pole. After that, connect the negative probe to the negative battery pole. Once all leads are connected, check the readout for the numerical results. Readings below the 12.4-volt range may indicate damage, while readings above this level suggest health.

This test can give you a rough idea of your battery health, but there are many other more subtle readings that require professional insights for proper translation. At Hamilton Ford in the Clovis area, our certified and skilled electrical system technicians can translate all of your electrical system readings for you.
