The G15000 is a portable automatic battery charger for both 12V and 24V lead-acid and lithium-ion batteries. Designed for charging a Car, Boat, RV, SUV, or Diesel Truck. It monitors battery activity for safe and efficient charging without any overcharge and complete with a built-in battery desulfator to rejuvenate underperforming and sulfated batteries. And comes equipped with an integrated JumpCharge engine start mode for jump starting dead batteries.
Ultimate versatility. Nine battery chargers in one.
Other brands require a separate battery charger for 12V charging, for 24V charging, for AGM batteries, for 6V charging, for cold conditions, for lithium-ion batteries, and yet another for battery desulfation. With our versatile multi-purpose battery chargers, as your needs and vehicles change, your charger won't. With a simple push of a button, you'll have the power to switch between various charging modes within one, complete battery charger. And it's equipped with a progressive repair method for recovering heavily sulfated and weak 12-volt batteries.
12V Repair Mode
A progressive battery recovery method for improving heavily sulfated and old 12V batteries that restore lost battery capacity.
13.6V Supply Mode
Converts to a constant current, constant voltage power supply for powering a 12V device, like a tire inflator, or retain memory when replacing a battery.
12V AGM+ Mode
Designed for charging 12-volt advanced AGM batteries typically found on start-stop vehicles and deep-cycle applications.
Designed for charging lithium-ion batteries that include a battery maintenance system (BMS), including lithium iron phosphate batteries.
Bigger is not better. It’s time to retire your grandpa’s battery charger.
Our next generation smart battery chargers utilize the latest advancements in battery charging technology. These switch-mode battery chargers were built on a high-frequency and high-efficiency platform, which converts energy 30,000 times faster than traditional automotive battery chargers. It's this efficient use of electricity is what makes our chargers not only compact, lightweight, and incredibly portable, but one that minimizes energy consumption and compliant with California Energy Commission regulations.
Worry-free. Safe to leave connected with zero overcharging.
Most manual, automatic or semi-automatic wheeled battery chargers continuously charge batteries, making them susceptible to overcharge, which limits battery life. Our intelligent battery maintenance technology monitors battery activity and only begins charging when needed, and allows for continuous operation without user intervention and zero risks of overcharging your battery.
JumpCharge. Integrated engine starter.
JumpCharge is an innovative engine starter feature for jump starting low-voltage or dead vehicle batteries. The JumpCharge process is different than a traditional automotive wheeled battery chargers. Whereas most car battery chargers overload the battery, JumpCharge uses a combination of high-current and high-voltage for engine starting. This precision charge control avoids overheating the battery and shortening battery life.
Plug-n-play. Battery maintenance made easy.
Plug-in, set and forget. It's no wonder it's the ultimate battery maintenance charger. Quickly connect and disconnect the battery charger when needed. It remembers the last charging mode and automatically resumes charging if accidentally disconnected or loses power. And it keeps any battery fully charged without supervision.
Remembers the last charge mode when accidentally unplugged or loses power. You'll never come back to a dead battery, again.
Designed for a rugged working environment. It's water, shock, dirt and dust-proof, and rated at IP60.
We don't design something that merely works, but remains safe after a major failure. So we built-in redundant levels of safety protection.5
5 Year Warranty.
Our battery chargers are built to last. That's why we back it up with an unbeatable warranty and combine it with unparalleled customer service.
Advanced diagnostics. Battery charging with intelligence.
Smart battery chargers can be frustration. It won't simply begin charging if it detects a weak or damaged battery or force charging if it detects an unsafe or abnormal charging condition. But prevention is just one aspect. Understanding and finding a solution is just as critical. Welcome to Advanced Diagnostics, which analyzes battery feedback and display a particular error pattern if a problem is detected. Each flash pattern tells you what's wrong, and how to quickly fix it.
Single Flash: Battery will not hold a charge and should be checked by a professional.
Double Flash: Possible battery short, and should be verified by a professional.
Triple Flash: Battery voltage is too high for the selected charge mode. Double check the battery matches the charge mode.
Error LED Solid Red: Reverse polarity. Reverse the connections to the battery.
Standby LED Solid Orange: Battery voltage is too low for the battery charger to detect the battery.
Battery Charging vs. Battery Maintenance.
Which battery charger is right for you?
Selecting the proper battery charger depends on your needs. Do you need to recharge a dead battery entirely, or just keep a battery at full charge? Battery charging means you need to recharge a dead battery fully, whereas battery maintenance requires a mere trickle charge. Most battery chargers perform both functions, but understanding their limits and the amount of time to recharge depends on the size of the battery and vehicle. The G15000 is designed for charging a Car, Boat, RV, SUV, or Diesel Truck. But its also can be used as a battery maintainer to keep both starter and deep-cycle batteries fully charged. The charging time chart not only helps you determine how long it will take to recharge but also its limits between battery charging and battery maintenance.
Efficient design. Compact, yet powerful battery charger.
A mix of electrical engineering and industrial design create a powerful battery charger into a tiny footprint. It uses high-frequency switch-mode technology to efficiency convert A/C power into safe D/C power for battery charging. And it's onboard microcomputer precisely controls the charging to minimize power loss to create an incredibly compact form factor.
Maximum performance. Rugged, water-resistant plug-n-play connectors.
Its heavy-duty battery clamps come integrated with over-molded eyelet terminals. So you can connect directly to any battery, or permanently mount the eyelet connectors for fast and easy charging. HD X-Connect is a robust and rugged connector that creates a reliable weatherproof connection that not only provides maximum current flow but easy to plug-n-play.
