INTRODUCTION
Charging Systems International has been manufacturing quality battery charging
systems since 1989. Our products are designed and built tough to withstand
intense vibration and extreme temperature var iations. Temperature
compensation is utilized to fully charge a battery in hot or cold environments and
all of our systems are controlled by microprocessors in order to assure precise
operation. All of our chargers have true reverse polarity protection and shut off
completely after each charge cycle.
