Choosing a Battery Charger

When it comes to Charging and Maintenance of your Batteries… be it Lithium (LiFePO4/LFP) or Lead/Acid, Antigravity Batteries has you covered with our ALL NEW “SUPER-CHARGER” line of Battery Chargers, but we also still carry great brands like CTEK and OPTIMATE.

In general, when purchasing a Charger you want the best performance within your budget, and this will ultimately depend on the Capacity/Amp Hours of your vehicle’s Battery or what you want to charge. Here is an overview of the best practices.

Best for Cars, Trucks, Marine, Larger Powersport Vehicles and Larger Motorcycles.
Cars/Trucks/SUVs usually have batteries in them that are generally 40Ah to about 90Ah (Amp hours); for this battery size you would want to use a Charger rated at 10A (Amps) for the best performance. A Charger with a higher Amp rating will charge the Larger-Capacity Batteries found in Car/Trucks much faster than a Charger with a lower Amp rating such as the typical 4A or 5A Chargers. Using a 10A Charger will ensure much faster charging than a lower amp Charger, and also overcome higher levels of parasitic drain in particular vehicles which would slow down a lower amp Charger. So for the fastest charging and being able to bring your battery out of a deep discharge quickly so you can get back on the road, you would want to go with a 10A Charger. 10A Chargers can also charge batteries up to 200Ah maximum, so if you have a Deep Cycle Battery or bank up to 200Ah, a 10A Charger could do that, but an even higher rated Charger is best above 150Ah.
Antigravity offers our SC-10 Super-Charger.

Best for basic Automobile use, Motorcycle and Powersports Vehicles.
Chargers rated in the 4A or 5A range will actually work perfectly fine to charge your Car or Light-duty Truck, but the fact is these 4 to 5 Amp Chargers will charge much slower and have less overhead for parasitic draws on the battery. They could take a day or even two days to fully recharge a deeply discharged Auto or Truck Battery; so while they do work fine, it is not the best option for that battery size. These smaller-Amp Chargers are often the best option for Smaller Batteries in the 4Ah to 40Ah range. For example batteries used in Motorcycles, Powersports Vehicles, Lawn and Tractor Vehicles or Smaller to Mid-sized vehicles. They can charge batteries up to 120Ah maximum. We offer a 4-Amp version of our Super-Charger called the SC-4; it offers the EXACT same features of the SC-10 Model but with a lower Amp Output.

Best for small batteries and low-level maintenance.
Chargers rated in the 1A to 2A range are generally intended for very simple maintenance and charging of batteries in the 1Ah to about 20Ah range. For example, while they can charge batteries up to 20 Amp hours, they will be slow to do it. Also these low-Amp Chargers cannot overcome higher levels of parasitic drains on them from any accessories or ECUs; sometimes parasitic draws can be high on some vehicles and diminish these smaller Chargers’ output. But a 1A or 2A Charger is quite good for vehicles that are stored during the winter and do not have high parasitic draws such as some Motorcycles, Riding Lawn Mowers, Watercraft and other vehicles that just need basic maintenance and are not used often. The best use for the 1-2 Amp rated Chargers is if you just need to maintain one smaller battery on one vehicle; then these are a great cost-effective option. Check out our SC-2.

Our Antigravity SUPER-CHARGERS are recommended for all of our Lithium Automotive and Powersport Batteries, with or without a BMS (EXCLUDING 16v Batteries). This includes our RE-START batteries (models with built-in jump-starting and full BMS protections), HEAVY DUTY batteries (models with full BMS but no restart), ultra compact Hi-Power SMALL CASE and XPS batteries, and older models (no BMS).

Why Antigravity?

Our Antigravity Super-Charger is sure to become your new go-to charger because of its versatility. It offers safe, high-tech Micro-Processor controlled accurate charging for 6V and 12V Lithium batteries, as well as 12V Lead/Acid batteries like FLA, AGM, GEL and others. You can use one Super-Charger to charge any of your vehicles; no need to have multiple chargers! The Super-Chargers also offer useful functions like a built-in Voltage Tester (not offered by other brands), Power Supply, Lithium BMS Re-Set, Maintenance mode, Recondition mode, and automatic Winter mode. The Super-Charger is incredibly easy to use and understand what is going on; its Large Digital Screen shows the Charging Voltage and Amps going into the Battery so you can easily know its status and if there are any errors…no more confusing LED dummy lights that don’t tell you what is going on with the charger. Once you’ve tried one you’ll understand!
