CRAFTSMAN 15A Battery Charger & Maintainer CMXCESM162 — 6V/12V Auto, Multi‑Stage Charging & Digital Readout

If you keep vehicles, motorcycles, or seasonal equipment around, a reliable charger that adapts to different battery types and voltages is essential. The CRAFTSMAN CMXCESM162 handles 6V and 12V batteries with automatic voltage detection, multi-stage charging, and built-in safety features. It supports standard flooded, AGM, deep-cycle, and LiFePO4 batteries, and offers a clear digital readout so you can monitor voltage and percentage of charge as the unit works.

How does the CMXCESM162 protect my battery while charging?

This model uses multi-stage charging and reverse-polarity protection to minimize risk and extend battery life. It automatically chooses the appropriate charge or maintenance current and halts if a dangerous connection is detected.

• Reverse polarity protection prevents damage from swapped clamps
• Multi-stage algorithm reduces overcharge risk during long maintenance
• Auto-detection selects 6V or 12V and the correct amp rate
• LEDs and digital display show voltage and charge percentage for visibility

What charging modes and amp rates are available?

The CMXCESM162 offers high-power charging and gentler maintenance modes to suit different needs. Use the 15A mode for faster charging of 12V batteries, and lower-amp modes for safe trickle maintenance or for 6V systems.

• 15 amp fast charge for 12V batteries for quicker top-ups
• 3 amp charging/maintaining mode for standard 12V applications
• 2 amp charging/maintaining mode for 6V batteries and long-term care
• Dedicated reconditioning/desulfation to help recover weak batteries

Which battery types and vehicles will this charger work with?

Designed for broad compatibility, this charger works on most common lead-acid chemistries and LiFePO4 batteries used today. It’s useful for passenger cars, trucks, ATVs, motorcycles, marine batteries, and deep-cycle systems.

• Compatible with standard flooded, AGM, and deep-cycle batteries
• Supports LiFePO4 batteries for many modern applications
• Works on gas and diesel vehicles as well as recreational equipment
• Includes 6-foot booster cables and a 6-foot power cord for reach and convenience

How do I know if the charger can diagnose battery health?

The CMXCESM162 includes a built-in battery tester and status indicators that flag poor battery condition. The unit reports voltage and percent charged on its digital display so you can quickly assess whether a battery needs reconditioning or replacement.

• Onboard battery test provides quick diagnostics before charging
• Digital readout displays voltage and charge percentage clearly
• Reconditioning mode attempts to improve sulfated battery performance
• Push-button interface and LEDs simplify operation and status checks

Who is this for? The CRAFTSMAN CMXCESM162 is aimed at car owners, shop mechanics, RV and boat enthusiasts, and anyone who maintains seasonal equipment. If you need one versatile unit to fast-charge, tender, test, and recondition a wide variety of 6V and 12V batteries — including modern LiFePO4 types — this charger delivers professional-grade features in a compact, user-friendly package. It’s a good fit for home garages, service bays, and mobile toolkits where dependable battery care matters.
