We offer industrial quality 12 volt battery chargers in amperages from 0.75 amps to 80 amps. Most are switch mode design, microprocessor controlled, which allows for smaller components, less heat generation (loss), and therefore fewer thermal management problems. Each 12 volt charger is a so called "smart" charger, utilizing multi stage charging, which provides efficient charging. The microprocessor takes information from the battery (voltage) and regulates the charge current to achieve maximum charge value without harming the battery, and ends the charge in a maintenance mode, suitable for long periods or storage. These features are considerable improvements over old battery charging technology, and eliminate undercharging or overcharging, both of which are detrimental to battery health. With an industrial quality 12 volt battery charger, you can attach and forget, and get maximum battery life and health. These are not the type of units you find in a department type store, and they may cost a little more, but the improvement in battery life, or proper operation of your prototype/production project more than pays the difference. There are some multi-purpose 6/12 volt and 12/24 volt units here as well.

The Schauer, Samlex, and some Quick Charge chargers are 3 stage units, providing up to the battery charger maximum output amperage(constant current), and monitoring of the charge voltage as it rises to the absorption set point. The absorption set point is generally between 14.1 volts DC and 14.7 volts DC in a 12 volt charger. The charger then maintains the absorption voltage (constant voltage) until the battery is fully charged (second stage). At this point, the charger drops the output voltage to the 3rd, or "float" stage, which is safe for long term battery maintenance. This float stage voltage is between 13.2 and 13.7 volts DC in a 12 volt battery charger.

The float stage in a microprocessor controlled battery charger is an excellent application of new technology in this computer age. Older 12 volt battery trickle chargers usually maintained a current 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 microprocessor only applies enough current (at the float voltage) to compensate for internal discharge.

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, to provide structural strength to the battery. This lead-antimony alloy construction leads to internal discharge rates of 8% to 40% per month in a wet lead acid battery. The sealed lead acid (SLA) types, Absorbed Glass Mat (AGM) and Gel, use a lead-calcium alloy, which is not of the same mechanical strength as the lead-antimony, since the construction (mats between the plates in the AGM battery, gelled electrolyte in the gel cell) stabilizes the battery structure. The lead-calcium batteries have 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 its ability to be recharged. A significant percentage of lead acid battery failure is from sulphation. Proper battery charging and use of floating chargers reduces or eliminates the sulphation problem.

The Samlex 12 volt chargers SEC1215, SEC1230, and SEC1245 are dip switch settable to deactivate the boost mode to function as a power supply at the float voltage, for backup power systems (UPS) for example, or power supply applications up to their rated output amperage. The Samlex chargers are also dip switch settable for true gel batteries ( gel cell ) and are user selectable for 115 VAC or 230 VAC input.

The Dual Pro marine battery chargers are 12 volt independent output, 4, 6, 10, and 15 amp, single output, temperature compensating battery chargers. They are a waterproof charger, and fully potted for vibration resistance. Most are available as portable units, with alligator clips. They are robust and durable chargers, which can be mounted and hard wired in a severe duty application for years of trouble free service. Most are also built in the USA, which is not particularly common for electronic items any more.

The Dual Pro 12 volt charger, in marine grade, is appropriate for applications where an exterior grade battery charger is required or desired. They have mounting flanges, and will endure water, vibration, and temperature. They are used in marine applications, like boats with a single battery for starting or trolling. We also use these for generator starting batteries and similar applications.

The Quick Charge 12 volt offerings include portable type chargers with handles, available with alligator clips or various industrial connectors, and on board units for mounting on industrial equipment or electric vehicles. There are also 60 amp industrial units. These are also built in the US and have a 3 year warranty.

Battery Doc supplies us with a 1.25 amp battery charger/maintainer, and a 2 amp waterproof charger/maintainer. These both come with detachable alligator clips, or ring terminals which can be permanently attached to a motorcycle, ATV, jetski, automotive, etc. 12 volt battery for plug-and-play battery maintenance.

We have the PulseTech Xtreme Charge 2.5 amp charger/desulfator in single and dual bank models. These incorporate PulseTech's patented desulfation technology with a smart 12 volt battery charger, for long term battery care, and restoration if necessary. These also come with detachable alligator clips and ring terminal harnesses.

Check out our selection from Japlar-Schauer, Samlex America, Quick Charge,and Dual Pro, if you are in the market for a 12 volt charger. At ChargingChargers.com, we select our battery chargers for reliability, design and function, warranty, and value. We can help with selection or advice by email (info@chargingchargers.com) or our tech line: (541) 582-4629. We deal with case pricing for quantity users.

ChargingChargers.com stocks commercial quality 12 volt battery chargers for marine, RV, automotive, electronic/security, industrial, and military applications. The cost of these units over department store type units is made up in efficiency and proper battery charging profiles, which translates into maximum battery life, and long term reliability. Most of these units are rated for 100% duty cycle, which means they can function at full amp load for extended periods.
