CRAFTSMAN 10A Wheeled 6V/12V Battery Charger & 250A Engine Starter – Manual Timer, Analog Ammeter

Built for garages, farms, and workshops that favor hands-on control, the CMXCESM233 combines a mid-duty 10-amp charging mode with high-current boost and crank capabilities. Its analog ammeter and mechanical timer put the operator in charge of each charging cycle, while the rugged steel housing, heavy-duty clamps, and solid wheels make it easy to move and withstand frequent use. Compatible with standard, AGM, gel, and deep-cycle batteries, this unit addresses both routine maintenance and hard-start situations.

How does the CMXCESM233 handle a dead or deeply discharged battery?

The charger offers dedicated boost and engine-start outputs to revive batteries many automatic chargers can’t detect. Use the boost modes to quickly add charge, then the 250-amp engine start to crank larger engines. The manual controls let you decide when to stop, and the analog meter shows charging progress at a glance.

• 250-amp 12V engine-start output for quick cranking power
• 50-amp 12V and 25-amp 6V/12V boost modes for deeply discharged batteries
• 10-amp 12V charge mode for regular battery replenishment
• Analog ammeter for straightforward monitoring

What safety and control features prevent overcharging?

Instead of relying on automatic algorithms, this model uses a 135-minute timer so you set the exact charge duration based on battery condition. When the timer expires, the unit shuts off to avoid extended charging. The visible ammeter helps you judge when to end a session early or leave it running for the selected interval.

• 135-minute manual timer for precise charge duration
• Automatic shutoff at timer end to limit overcharging risk
• Clear analog readout to track current flow during charging

Which battery types and vehicles will this charger support?

The CMXCESM233 is designed to work with a wide range of 6V and 12V battery chemistries and applications, making it suitable for both small motors and larger engines. It supports common automotive and leisure batteries so you can use it across different machines in the yard or shop. The heavy-duty clamps and output cables are sized to deliver reliable current where it’s needed.

• Compatible with standard, AGM, gel, and deep-cycle batteries
• Works with cars, trucks, SUVs, motorcycles, ATVs, RVs, and marine batteries
• Front-mounted booster cables and robust clamps for solid connections

How durable and mobile is the charger for workshop use?

This unit is built with a steel case and rugged components intended for repeated shop use. A retractable handle and solid compact wheels make moving the charger between bays or around a yard straightforward. The construction balances portability with the stability required to handle high-current starting and boost operations.

• Sturdy steel housing resists wear in workshop environments
• Retractable handle and solid wheels for easy transport
• Heavy-duty clamps and gauge-forward layout for practical serviceability

Who is this for: The CRAFTSMAN CMXCESM233 suits experienced hobby mechanics, small-fleet operators, and property owners who prefer manual, timer-controlled charging and need strong starting power on demand. If you want a durable, no-frills wheeled charger that offers both routine 10A charging and high-current boost/start capabilities for a variety of 6V and 12V batteries, this unit provides a practical, workshop-ready solution.
