We carry industrial quality battery chargers, marine chargers, sealed batteries, solar chargers, inverters, built for commercial, marine, military, and home use. We supply components for 12 volt through 48 volt DC systems and have a Technical Advisor to aid in selection of the appropriate item for your specific application. We have recently added application specific golf cart battery chargers, made in the US, industrial quality, 3 year warranty, and reasonably priced, and sealed lead acid batteries, both AGM and true Gel types.

At ChargingChargers.com, we distribute industrial quality battery chargers in amperages from 2 amps to 45 amps, and 12 to 48 volts. All of our battery chargers are multi staged microprocessor controlled, which provides efficient charging using constant current up to the absorption point, and then holds the absorption voltage (constant voltage) until the battery is fully charged. At this point, the battery charger drops the output voltage to the "float" stage, which is safe for long term battery maintenance. The Dual Pro chargers are an exception to this, as they shut completely off, and the computer chip analyzes battery voltage, initiating a new charge cycle if conditions warrant it. The float stage in a microprocessor controlled battery charger is an excellent application of new technology in this computer age. Older battery trickle chargers usually maintained an amperage level that was too high for long term maintenance, and overcharged batteries, thus requiring constant monitoring. The new chargers can be left connected for indeterminant periods, and the battery charger only applies enough current to maintain the float voltage, or recharging as needed, compensating for internal battery discharge, preventing sulphation, and providing maximum battery life, with minimum observation.

This internal discharge (self-discharge) is a common characteristic of lead acid batteries, but varies with battery type. The wet, or flooded lead acid batteries are constructed of a lead-antimony alloy, and have an internal discharge rate of 8% to 40%. The sealed lead acid battery types, Absorbed Glass Mat (AGM) and Gel, use a lead-calcium alloy, which has a lower internal discharge rate, between 2% and 10% per month. This internal discharge leads to suphation of the battery plates, which can harden and either reduce battery capacity, or destroy a lead acid battery's ability to be recharged. A significant percentage of lead acid battery failure is from sulphation. Proper battery charging and use of floating chargers eliminates the sulphation problem.

Most of the battery chargers ChargingChargers.com offers will function as a power supply and feed a DC load, with a battery in the circuit, with the exception of the Dual Pro models. The smaller (5 to 12 amp) Japlar-Schauer battery chargers will feed small loads up to about 1 amp or a little more without switching back to the absorption stage and raising output voltage. The Samlex battery chargers are dip switch settable to deactivate the boost mode to function as a power supply at the float voltage, for backup power systems or power supply applications up to their rated output amperage. The Samlex chargers are also dip switch settable for true gel batteries (gel cell). The Dual Pro chargers are available with a true gel cell battery microprocessing chip. The Dual Pro Eagle series chargers in 36 and 48 volt are the basis of our golf cart battery charger lineup, and are available with cart-specific connectors (plugs) for EZ-GO™, Club Car™, Yamaha™, and others with generic connector plugs like the Anderson Power Pole series.

Check out our selection of battery chargers from Dual Pro, Japlar-Schauer and Samlex America. At ChargingChargers.com, we select our battery chargers for reliability, design and function, warranty, and value. We deal with case pricing for quantity users.

ChargingChargers.com carries the Samlex line of high quality DC DC converters for military, industrial, lab, and other applications which require a DC voltage step up (boost) or step down (buck). The high efficiency of these converters allows a compact size for the amp output, and lower heat generation (a product of inefficiency).

Military and heavy equipment applications may use DC to DC converters in a 24 volt DC system to provide a regulated, stable DC voltage source for 12 volt DC electronic devices such as radios, computers, data loggers, sound equipment, lights, etc. Marine systems can use DC converters for sonar, radar, instrumentation, computers, stereos, etc. Buses and heavy trucks are also appropriate uses for the DC converters.

A DC to DC converter is an electronically controlled device that pulls equally from the parent voltage and supplies a precise, regulated voltage in the desired output amp range. They usually can tolerate a fairly wide input voltage, allowing for battery pack discharge, and charging system voltage variance.

ChargingChargers.com has access to various wattage DC to DC converters, in step up and step down versions, and non-isolated and isolated types. We like the Samlex DC to DC converters because of their reliability, variety, and suitability in many applications. For more information, see our DC converter tutorial.

Power inverters are electronic devices which convert DC power stored in a battery or battery bank into AC power for use in devices which run on wall outlet (utility grid) type power. They come in various inverter input voltages (12 volt, 24 volt, 48 volt DC), and are rated in continuous output wattage, and surge wattage. They are available as modified sine DC to AC inverters, and pure sine wave inverters. Modified sine inverters use a stepped output wave to approximate the smooth sine wave AC output provided in utility grid power systems. Pure sine power inverters (true sine) have a proper and well regulated pure sine wave output, that allows devices to run on the type of power they were designed for. This is more of an issue for some devices than others. We only carry pure sine inverters.

• The output is a pure sine wave with very low harmonic distortion and clean, utility grid type power.
• Inductive loads such as motors and microwaves run quieter, faster and cooler.
• Audible and electrical noise in fans, fluorescent lights, amplifiers, TV, fax and answering machines is reduced.
• Prevents computer crashes, incorrect print outs, and glitches in monitors Some devices may not work properly with modified sine inverters and may get damaged.

Though more expensive than modified sine inverters, the DC to AC pure sine power inverters provide better performance and longer life for most of the devices they power, which ultimately results in lower overall cost. For video and audio applications, we always recommend a pure sine power inverter. For more information, see our inverter tutorial.

ChargingChargers.com specializes in small solar panel applications in 12 volt and 24 volt, and medium 12 volt solar panel systems. We can advise and supply solar solutions for battery maintenance of single or multiple battery packs, or solar panel systems with small or intermittent current drains. Solar battery chargers can be appropriate for security systems (video, alarm), remote telemetry, radio repeaters, solar gate openers, solar fence charger, generator/pump starting batteries, heavy equipment batteries, GPS locators on semi trailers, marine applications, or as a solar trickle charger and many other situations. Appropriate lead acid battery types for these systems include the flooded, or wet batteries, absorbed glass mat (AGM), and sometimes the true Gel battery (Gel Cell).

We are an experienced solar battery charger supplier. Our technical advisor has worked with the U.S. EPA on remote montoring stations, our U.S. military (for small mobile applications in Iraq, infrequently used vehicle battery maintenance, thermally activated training aids, and more), Homeland Security projects (parking/structure) video surveilance/recording, many colleges and universities for scientific monitoring and student projects, and the solar powered video documentation of the rebuilding at Ground Zero in New York called Project Rebirth.

For more information, see our solar tutorial. We have access to many more solar components, so give us a try!

We are adding some of the sealed lead acid batteries to the site, both AGM (absorbed glass mat) and true Gel types. The manufacturer we are dealing with is Universal Power Group headquartered in Texas. While our charger and inverter lines have steered clear of Chinese made products, the Universals are made in China in a plant partially owned by Universal. This gives them a say that a simple customer/importer doesn't have. The quality has been superb, and customer service outstanding. This is not the case with all imports. The sealed batteries are DOT approved for air transport, and deemed non-hazardous. This makes them suitable for shipping around the country without hassles. It also allows travelers flexibility to carry them in luggage, or take a mobility chair or scooter abroad. All models we carry are designed to be cycled, dead if necessary, and give their rated service life. Ask about quantity purchases, or sizes not found on the site.
