Product Description
Is a dead battery turning your day upside down? The Schumacher DSR145 is a battery charger and engine starter in one. You can jump-start a stalled engine, recharge a drained battery, and keep it healthy afterward with a single tool. It's built for professional shops, but it's simple enough for any home garage.
Stop Replacing Batteries That Aren't Really Dead
Plenty of batteries are just drained, or have sat so long they stopped accepting a charge. The DSR145 helps you tell the difference, and it often fixes the problem on the spot.
The digital display shows voltage, charge level, and charging system status. If something goes wrong, you get a fault code instead of a mystery.
Made for the Jobs You Actually Have
- Classic and project cars that sit for months at a time
- Trucks, SUVs, and diesels that need serious cranking power
- Motorcycles, ATVs, and other powersports vehicles
- Busy repair shops and lots that need cars ready to roll
Simple to Use
Connect the clamps, choose your battery type, and press start. The charger handles the rest and switches to maintain mode when it's done.
Push-to-start charging lets you begin on batteries that have drained very low. If a battery has been sitting discharged, the charger can detect it and begin recovery on its own.
Know Before You Buy
The DSR145 plugs into a standard 120V outlet and comes with a 6-foot power cord and 6.5-foot booster cables. It weighs 13.8 lb and measures about 10 x 11.88 x 6.13 inches. It's backed by Schumacher's 1-year limited warranty.
Ready to stop worrying about dead batteries? Add the Schumacher DSR145 to your cart and keep your engine turning.
Frequently Asked Questions
What types of batteries is the DSR145 compatible with?
A: It charges 6V and 12V lead-acid batteries, including standard and AGM types. It is not designed for dry-cell batteries or for charging a frozen battery. Check your battery's voltage before connecting.
Can I use it to jump-start a car?
A: Yes, as long as a battery is installed in the vehicle. Connect the clamps, plug in the charger, select Engine Start, press Start, and crank for up to 7 seconds. If the engine doesn't start, wait for the 3-minute cool-down before trying again.
Can I charge a boat battery with it?
A: Yes, but the battery must be removed from the boat and charged on shore. Charging aboard requires equipment made specifically for marine use.
How long does it take to charge a battery?
A: At the 6A setting, a small car battery (300 CCA) takes about 4 hours, and a large one (1000 CCA) takes about 10 hours. These times assume a battery that is 50% discharged. Age and condition can change them.
Can I use an extension cord?
A: The manufacturer recommends against it. If you must, use a properly wired cord with a matching plug and heavy enough wire: 18 AWG up to 25 feet, or 16 AWG up to 50 feet.
