CRAFTSMAN 15A Battery Charger & Maintainer CMXCESM162 — 6V/12V Auto, Recondition & Digital Readout

The CRAFTSMAN CMXCESM162 is a fully automatic 4-in-1 battery charger and maintainer that charges, maintains, tests, and reconditions 6V and 12V batteries with up to 15 amps of charging power.

This compact, AC-powered unit combines a powerful 15A charging mode for 12V batteries with lower-rate maintenance settings and compatibility for AGM, deep-cycle, standard, and LiFePO4 batteries. Built-in safety features and automatic voltage detection make it practical for garage use, seasonal storage, or roadside battery recovery. The CMXCESM162 provides digital readouts, LED status indicators, and a user-friendly push-button interface so you can monitor battery condition and charge progress at a glance.

How does the CMXCESM162 decide which charge mode to use?

The charger automatically detects the battery voltage and selects the appropriate charging routine, so you don’t need to guess the right setting. It runs multi-stage charging to bring batteries to full capacity safely and will switch to a low-rate maintenance mode once charging is complete.

• Auto voltage detection for 6V or 12V batteries
• Multi-stage charging to reduce overcharge risk
• Automatic switch to trickle/maintain mode
• Push-button selection for manual override when needed

Can this unit revive or test a weak battery?

Yes—the CMXCESM162 includes a reconditioning (desulfation) function and a built-in battery tester to evaluate health. The reconditioning mode helps remove sulfation build-up on lead-acid batteries, and the tester flags batteries that are no longer serviceable.

• Desulfation mode for restoring weak lead-acid batteries
• Integrated battery health test with clear results
• Displays voltage and percentage of charge on digital readout
• Alerts for batteries with poor condition to avoid unreliable starts

What safety and convenience features protect my vehicle and battery?

The charger is designed with several safeguards to protect both the battery and vehicle electronics. Reverse polarity protection and automatic current regulation prevent damage from incorrect connections or over-current events, while the LED and digital indicators keep you informed during use.

• Reverse polarity protection to prevent clamp-misconnection damage
• Current-limited charging to avoid overheating and overcharge
• LED indicators plus digital voltage and charge percentage display
• 6-foot booster cables and 6-foot power cord for flexible placement

Which vehicle and battery types work with this charger?

The CMXCESM162 supports a wide range of battery chemistries and vehicle classes, making it versatile for everyday drivers and hobbyists. It handles motorcycles, cars, trucks, ATVs, and many marine batteries when used with compatible battery types.

• Compatible with 6V and 12V standard lead-acid, AGM, deep-cycle, and LiFePO4 batteries
• Suitable for cars, trucks, SUVs, motorcycles, ATVs, and many marine applications
• Multiple charge rates: 15A fast charge (12V), 3A and 2A maintenance options
