You make enough stops during the day. Don't let your battery stop you, too! Constant stops can shorten the life of any ordinary commercial battery. Your customers depend on you to deliver on time...time after time. To keep them satisfied, you need a battery you can depend on to keep your trucks on the move. These Dual Purpose batteries are specially designed to withstand the daily stop-and-start abuse of multi-stop delivery vehicles and reefers. These batteries provide plenty of cold cranking power for easy starting and ample reserve power to handle the cycling demands typical of these types of commercial applications. Special computer-aided design and heavy-duty manufacturing techniques mean more durability for line haul trucks, buses, farm tractors and off-road equipment. Premium deep pocket envelope separators, protect the plates on all four sides to dramatically reduce shorting and extend service life. Genuine calcium lead alloy provides longer waterless operation and extended battery life. Anchor-locked elements with tight-pack commercial plates resist the damaging effects of vibration, delivering more power-per-pound than other batteries.
