CRAFTSMAN 1.5A Battery Charger & Maintainer for 6V/12V Batteries - Compact, Automatic Reconditioning

The CRAFTSMAN CMXCESM259 is a compact, fully automatic 1.5A charger and maintainer that charges, maintains, and reconditions 6V and 12V batteries safely for cars, motorcycles, ATVs, and marine use.

If you store seasonal vehicles, run a workshop, or simply want to avoid a dead battery, this microprocessor-controlled unit offers a practical, low-effort way to keep batteries ready. It detects voltage automatically, applies multistage charging, and switches to a smart trickle to prevent overcharging while preserving battery life. The CMXCESM259 works with common battery chemistries and includes safety features that make it usable by hobbyists and pros alike.

How does the CMXCESM259 protect batteries during charging?

The unit uses microprocessor logic to monitor voltage and current and moves through controlled charging stages to bring a battery to full capacity without overheating or overcharging. It automatically drops to a maintenance mode when charging is complete.

• Multistage charging prevents stress from high current at low voltages
• Smart trickle charge maintains charge without causing overcharge
• Reverse polarity protection guards against clamp mistakes
• Desulfation mode helps address sulfation buildup in neglected batteries

Which battery types and vehicles can I use this with?

Designed for both 6V and 12V systems, the charger is compatible with standard flooded, AGM, gel, and many deep-cycle batteries. It is suitable for motorcycles, ATVs, cars, trucks, SUVs, and many small marine batteries.

• Works with gas and diesel vehicles that use 6V or 12V batteries
• Supports common battery chemistries: flooded, AGM, gel, deep-cycle
• Good for lead-acid batteries found in passenger and powersport vehicles
• Can be used as a tender for seasonal equipment and stored vehicles

What safety and convenience features does it include?

The CMXCESM259 includes built-in safeguards and practical accessories to simplify installation and use. Its compact housing makes mounting easy while accessories let you connect quickly and securely.

• Reverse polarity protection prevents damage from incorrect clamp hookup
• 6-foot AC cord and 5-foot booster cables give flexible reach
• Quick-connect clamps and ring terminals included for permanent or temporary hookups
• Wall-mount slots let you store the unit off the bench and out of the way

Can this charger improve an older or neglected battery?

It offers a reconditioning mode that uses controlled pulses to reduce sulfation and restore some lost capacity on eligible batteries. While it can improve performance in many cases, results vary by battery age and damage level.

• Desulfation helps dissolve buildup that forms on lead plates
• Reconditioning cycles are automatic and require no user timing
• Not all deeply damaged batteries can be fully recovered
• Best used as part of regular maintenance to extend battery life

Who is this for? The CRAFTSMAN CMXCESM259 fits homeowners, DIY mechanics, and small-fleet owners who need a dependable, low-maintenance solution for maintaining multiple 6V and 12V batteries. If you keep seasonal toys, perform routine vehicle upkeep, or want an easy way to preserve battery health without frequent monitoring, this charger provides a safe, compact, and feature-rich option. It’s especially useful where space is limited and where a wall-mountable, plug-in maintainer reduces clutter and hassle. Note: the unit must be plugged into AC power during operation and is intended for compatible lead-acid battery types; it is not a jump starter.
