Frequently Asked Questions ❓

How long does it take to fully charge a dead battery?
Charging time varies depending on battery size and condition. A typical car battery may take 2-6 hours using the 6A charge mode.

Can I leave the charger connected to maintain my battery?
Yes! The 2A maintenance mode is designed for long-term connection. The float mode monitoring prevents overcharging by adding charge only when needed.

Does this work with all types of vehicles?
The CMXCESM253 is compatible with most cars, SUVs, trucks, and marine applications that use 6V or 12V batteries, including standard, AGM, gel, and deep-cycle types.

How do I know if my alternator is working properly?
Use the built-in alternator tester function. Start your vehicle and check the reading on the digital display. A properly functioning charging system should show approximately 13.8-14.8 volts.

What does the desulfation mode do?
The desulfation mode helps break down sulfate crystals that form on battery plates over time. This can restore performance and extend the life of older batteries that have been sitting unused.
