In technical terms, the Tesla Battery Chargers use a proprietary, computer controlled, pulse technology that operates in the megahertz range, to charge batteries. Or in layman’s terms, the chargers use a digital technology that pulses power, thousands of times per second, into the batteries instead of using constant power. Now don’t worry, even though what these chargers do may sound complicated, which it is, they are completely automatic. The on-board computer tests the battery before each pulse is delivered and only delivers what the battery needs. This ensures that the electrical energy is delivered to the battery in the most efficient way possible, which results in less energy consumption by the charger. Most battery chargers on the market today use brute force to re-charge a battery. This new technology enables batteries that are very weak, or even ones that are un-chargeable by any other charger, to be charged using a Tesla Charger, and thus be put back to useful service. Which not only helps keep batteries out of the landfills, but keep more money in your pocket. Tesla Chargers really are the most advanced battery charging systems available in the world today.

There is a Tesla Charger that for every kind of rechargeable battery that you own. The Universal 1AU is the most versatile battery charger of the lineup. No kidding! It will recharge and restore any rechargeable battery from as tiny as a 1.2 Volt Ni-cad, your cordless and cell phones, your laptop, rechargeable flashlight, or plus, any type or voltage of portable power tool batteries, up to and including 24 volts!
The most popular model is the 2A12 charger. Which is made to charge 12 Volt lead-acid batteries. Which include the small gel-cell type, the start type used in automobiles, to even the deep-cycle Marine batteries. It’s only rated at 2 amps, but this little chargers size fool you, it is a serious work horse.
Tesla Chargers also have a line of industrial battery chargers. The 30A12 and 15A24 chargers are designed for most larger sizes of 12V and 24V batteries. The units also use the automatic “cycling” to charge and load the battery in sequence, to increase the capacity of older batteries quickly.
Then we have the E-Car charger unit that works on 72 Volt to 144 Volt systems found in electric vehicles, up to 250AH. This is the best charger available, anywhere, for an electric automobile. Not only does it maintain the battery capacity at maximum, it also ensures every charge provides maximum mileage, year after year.
The 20AU charger was designed for banks of batteries ranging from 24 Volts up to 72 Volts. These battery banks are commonly found in fork lifts. But this charger can also be used to recondition and extend the life of battery banks used in wind, solar and water power generators.
