Chargers for Large-Cell Batteries

After the battery is fully charged, these chargers continuously provide a low-level charge to maintain the battery without overcharging.

Chargers with reverse-polarity protection prevent sparks and short circuits if the connectors touch or if they're not connected properly to the battery.

Chargers that cannot be sold to the regions listed are restricted by local energy efficiency regulations or product labeling requirements.

Water-Resistant Chargers for Large-Cell Batteries

Charge batteries even in wet environments—a sealed housing keeps water out. They have reverse-polarity protection to prevent sparks and short circuits if the ring terminals touch or if they're not connected properly to the battery. After the battery is fully charged, they continuously provide a low-level charge to maintain the battery without overcharging.

Hand-Held Charger/Starters for Large-Cell Batteries

Small enough to carry, these charger/starters provide a 125-amp starting current. They have reverse-polarity protection to prevent sparks and short circuits if the clamps touch or if they're not connected properly to the battery. After the battery is fully charged, they continuously provide a low-level charge to maintain the battery without overcharging.

Charger/Starters for Large-Cell Batteries

Wheel these charger/starters to batteries that need maintenance. They provide higher starting currents than Hand-Held Charger/Starters for Large-Cell Batteries. All have reverse-polarity protection to prevent sparks and short circuits if the clamps touch or if they're not connected properly to the battery.

Automatic charger/starters turn off when the battery is fully charged, but will continue to monitor the battery and turn back on if voltage drops.

Manual chargers can be set to continuously charge, or set to shut off automatically with a timer.

Hand-Held Starters for Large-Cell Batteries

Once fully charged, these starters store enough power to jump start a battery multiple times. All have reverse-polarity protection to prevent sparks and short circuits if the clamps touch or if they're not connected properly to a battery. They also have a USB port to charge mobile devices such as smartphones and tablets. To recharge, connect them to a USB port with the included cord.

Starters with a 12-volt vehicle plug can be charged in a vehicle outlet.

For 2,000A and 3,000A starters, use the adapter cord with the 12-volt vehicle socket to charge devices that require more power than what the USB cord delivers.
