BATTERY

摘要

Batteries for boats and vehicles require a CRA tcranking) battery and an AUX (auxiliaries) battery to ensure a start. The preferred version has an AUX battery made of parallel plates and a CRA battery made of parallel plates lying in a monobloc case in face to face positions. Each battery has a pair of CRA terminals for the electric starter and a pair of AUX terminals for the AUX loads of the vehicle and the alternator. The AUX and CRA negative are joinable by a link or a switch so that a single earth connection is made to the vehicle. Alternatives show the AUX and CRA batteries side by side, at degrees, providing 24v or 36v with a 12v tap; a CRA battery with two AUX batteries one for constant voltage equipment. Advantageous disposition of terminals simplifies connections to vehicle wiring and to a like battery.
