MRC Technology Inc. was founded to bring the advanced technology of solid-state electronics to industrial applications.  While solid-state technology has created a revolution in consumer goods and sophisticated electronic equipment, this knowledge has yet to be applied to many industrial and commercial processes.
We invented the first battery saver using this technology.

MRC Technology tests new concepts for improving the reliability and durability of many long accepted but less than satisfactory systems such as battery chargers and motor starters. On site automated manufacturing processes allow for constant quality control of the product as well as low cost production. All of our products are made in the USA.

MRC SLIM CHARGER

The SLIM CHARGER is a state-of-the-art lead acid battery charger that makes all the other chargers obsolete. Simple to use, the Red LED indicates the charger is operating and the Green LED indicates the battery is 100% charged. Each model has 6 ft. AC cord and 6 ft. DC output cord.

This is the only charger you will need for:

Automobile
Motorcycle
Boat
Scooter
RV
Tractor
Generator

More than one-half million in use by satisfied customers.

The SLIM CHARGER can be used as an overnight charger or battery maintainer. Our charger will not cook, overheat, or over charge your battery and maintains a full charge unattended. When the battery is fully charged the SLIM CHARGER automatically reduces the charge rate to 10mA to prevent over charging.

HOW THE SLIM CHARGER WORKS

To properly charge a battery, the charger has to be capable of taking a battery through three charge stages. The first stage is a bulk charge stage in which the charger supplies a majority of the power to the battery until it reaches termination voltage. During the second stage the termination voltage has to be high enough to fully charge the battery and remain at that constant termination voltage for an hour to destratify the electrolyte and return it to a set level of specific gravity. Finally, in the third stage, the charger goes into a standby mode that keeps a battery fully charged without over charge.

MRC BATTERY SAVER

These solid state automatic battery savers are designed to charge 12-volt liquid lead acid batteries to full level. A battery can self discharge in one month, use MRC-12C and MRC-12R to retain full charge during long storage periods. Voltage is sufficiently low so that battery electrolyte will not boil out during long term charging. The maintenance current is low (10-40 mA).

Keep batteries at full charge all off season.

Protects your battery during storage.

When a battery completely discharges it "sulfates" and causes permanent damage to battery. By keeping the battery fully charged damage caused by self discharge during storage is eliminated.
