Product Description
Full Control for Hands-On Folks
Are you tired of smart chargers that give up on a deeply drained battery? This manual battery charger puts you back in charge. You pick the rate, set the timer, and watch the meter until the job is done.
It also works as an engine starter, so one unit covers the charge and the jump when a battery quits in your driveway or shop. No more waiting on a ride or a borrowed set of jumper cables.
Why Hands-On Charging Makes Sense
- Give a very run-down battery the push it needs before you try to start the engine.
- Use one charger for the cars, trucks, and equipment you keep up around the property.
- Enjoy a no-frills dial-and-meter design that reviewers praise for dependable, long-term performance.
Built for the Garage, Barn, or Shop
This charger plugs into a standard 120V outlet, so it's made for the workbench rather than the roadside. Color-coded clamps help you connect with confidence, and the handle makes it easy to carry from one project to the next. Its metal case is built for the bumps of a busy shop.
What to Expect Before You Buy
Manual means you do a little math. The owner's manual includes a simple formula and charge time chart to help you set the timer. Plan to stay nearby, since this charger must be monitored while it works.
It's not a set-it-and-forget-it unit, and that's exactly why hands-on folks like it.
Take Charge of Your Battery

Frequently Asked Questions
Can I use the engine start feature without a battery in the vehicle?
A: No. Engine Start must be used with a battery installed, because using it without one could damage your vehicle's electrical system. Crank for up to 5 seconds at a time, then wait 3 minutes before trying again.
What types of batteries does it work with?
A: It works with 6V and 12V lead-acid batteries, including standard, AGM, gel, and deep-cycle types. It is not meant for dry-cell batteries or lithium batteries.
Can I charge a motorcycle, ATV, or garden tractor battery?
A: This charger is designed for larger batteries. The manual lists small batteries (roughly 6-32Ah) as not recommended at its charge rates, so check your battery's Ah rating first.
How do I know how long to charge?
A: The manual gives a simple formula based on your battery's Ah rating and how drained it is. You can also watch the ammeter. When the needle stops dropping, your battery is charged. Always stay nearby while charging.
Can I charge a boat battery while it's on the boat?
A: No. A marine battery should be removed and charged on shore. Charging it on board requires equipment specially designed for marine use.
