  • TypeWired Car Charger
  • Automatically detects 6V or 12V batteries for versatile charging
  • LCD screen shows measured voltage and charge level bar graph
  • 75A maintainer prevents overcharging during long-term storage
  • Built-in protection against short circuit, reverse polarity, overcharge and overheat
  • Hook attachment keeps unit outside the work area for safety

Automatic 6V/12V Charger for Lead-Acid Batteries

This fully automatic maintainer delivers 750 mA to keep stored lead-acid batteries at full charge. It accepts 105-125 V AC at 60 Hz or 220-240 V AC at 50 Hz and automatically senses whether the connected battery is 6 V or 12 V. Protection circuits guard against overcharge, overtemperature, short circuit and reverse polarity. The unit is intended for vehicles and equipment that use small-capacity lead-acid cells.

Charging Limited to 0.75 A for Maintenance Duty

The 750 mA output suits long-term maintenance and slow recharge of small batteries such as those in motorcycles, lawn tractors or seasonal vehicles. It will not rapidly restore a deeply discharged high-capacity automotive battery. DC charging voltages are fixed at 7.2 V for 6 V batteries and 13.9 V for 12 V batteries, so the device cannot be adjusted for other chemistries or voltage levels. Users needing faster bulk charging or support for lithium chemistries must choose a different product.

Hook Mount and LCD Readout for Bench Use

A built-in hook lets the charger hang outside the immediate work area, keeping cables clear of moving parts and hot surfaces. The LCD shows measured voltage with a bar-graph charge indicator and digital prompts that guide each step of the process. Wired input and output leads require access to a mains socket and the battery terminals. The electronic design has no user-serviceable parts inside.

Questions about this item

Should I pick the 6 V or 12 V setting for my battery?

The charger automatically senses 6 V or 12 V lead-acid batteries, so no manual selection is needed.

What does the 0.75 A charge current mean for a typical car battery?

It delivers a 750 mA maintenance charge, suited for keeping stored batteries topped up rather than fast recharging a flat one.

What input voltage range does the charger accept and what limits its use?

It runs on 105-125 V AC at 60 Hz or 220-240 V AC at 50 Hz, so it works on standard mains supplies in most regions.
