Schumacher Electric 6A Battery Charger & Maintainer FR01335 — 6V/12V with 200A Engine-Start and Reconditioner

The Schumacher FR01335 is a 4-in-1, fully automatic 6A charger, maintainer, reconditioner and 200A-capable engine starter designed for 6V and 12V lead-acid batteries on farms, trucks, SUVs and everyday vehicles.

This heavy-duty unit combines shore‑power charging with a high-current engine‑start boost and a multi-stage maintenance mode to protect battery health. Microprocessor control automatically senses voltage and manages charge rates for standard, AGM and gel batteries, while reverse-polarity protection and a clear digital interface keep operation safe and straightforward. Schumacher engineered the FR01335 for rugged environments where reliable starts and extended battery life matter.

How does the FR01335 get a stuck engine running?

The FR01335 provides a high-current boost to crank engines quickly without the need for another vehicle. For 12V systems it delivers up to 200 amps of starting current and up to 150 amps for 6V systems, enough to restart most cars, trucks and farm equipment in one session.

• 200A engine-start capability for 12V batteries and 150A for 6V batteries
• 20–40A boost charge to revive deeply discharged batteries before starting
• 6-gauge, 6-foot heavy-duty output cables for reliable power transfer

Will this charger keep my battery healthy long term?

Yes — the FR01335 uses a multi-stage charging algorithm and trickle‑charge maintenance to avoid overcharging while replenishing batteries safely. It also includes a reconditioning/desulfation mode intended to restore lost capacity in sulfated lead‑acid batteries, helping extend usable life when recovery is possible.

• Automatic multi-stage charging to maximize battery longevity
• Smart trickle/maintain modes for long-term connection without damage
• Dedicated recondition/desulfation cycle to help recover underperforming batteries

How easy and safe is it to use on a farm or in a garage?

The FR01335 is built for practical day-to-day use: plug it in, choose charge or boost mode via push buttons, and monitor the scrolling digital display and LEDs. Integrated safety features such as reverse-polarity protection and microprocessor control reduce the risk of operator error and protect both battery and vehicle electronics.

• Reverse-hookup protection prevents damage from incorrect clamp connections
• Clear digital readout plus LED status indicators for intuitive operation
• Start/stop interface and push-button controls designed for quick selection

What types of vehicles and batteries does it support?

The unit is compatible with a wide range of gasoline and diesel vehicles, from motorcycles and ATVs up to farm tractors and full-size trucks. It works with both 6V and 12V lead‑acid chemistries including conventional flooded, AGM and gel batteries, making it versatile for mixed fleets.

• Supports 6V and 12V systems for motorcycles, cars, trucks, SUVs and farm equipment
• Compatible with standard, AGM and gel lead‑acid batteries
• AC powered with 6-foot power cord; quick-connect clamps included for convenient setup

Who is this for: The Schumacher FR01335 is aimed at owners and operators who need a single, rugged unit that both revives and maintains batteries—farmers, ranch hands, fleet managers, mechanics and serious DIYers. It’s ideal if you want dependable engine starts, on-demand boost power, and automatic maintenance in one compact package that stands up to heavy use.
