Product InformationStore Part Number: G15000


The NOCO G15000 is a portable automatic battery charger and maintainer for both 12V and 24V lead-acid and 12V 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.

Other brands require a separate battery charger for 12V charging, for 24V charging, for AGM batteries, for cold conditions, for 12v 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 (5 Amp)

  • 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.

12v Lithium Mode

  • Designed for charging lithium-ion batteries that include a battery maintenance system (BMS), including lithium iron phosphate batteries.

JumpCharge Mode

  • 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.

Excellent Charger!
I have a large Diesel motorhome with an 8D 1400CCA battery. The key go left on accessory and drained the battery completely. My original charger would get it back to 70% but no more. I contacted the support team and Anthony responded quickly and we came up with this charger. I made the online purchase and it arrived quickly. I connected it to my motorhome battery and it went through a charge and then repair cycle bringing it up to 100%. I also put it on one of my ATVs that had a battery the wouldn't hold a charge and it now is maintaining a charge. I am extremely pleased with the quality of the materials used for both the case and the cables. I absolutely recommend this charger. Work with the support team to get the right one for your needs and you will be happy!
