Some Battery Manufacturer’s Make Claims…Crown is Making History
Nobody builds them like Crown. Nobody. Because no one else has made the investment in people and facilities like they have, they do one thing: build a better commercial battery. Their modern high-performance designs make them the finest engineered batteries you’ll find anywhere. With advanced plate and internal construction, Crown Batteries outlast the competition. Crown’s modern one-piece solid-cast design provides a lower internal resistance, because lower resistance means more efficiency. Charging and discharging are optimum, therefore, providing a longer battery life. Dense TBLS (tetra-basic lead sulfate) crystal content in the positive plate ensures more resistance to breakdown providing longer life and consistent performance, consequently giving you a better battery.
Commercial Battery
Crown Battery. The line that separates heavy duty batteries from heavy duty wannabees. No other line is engineered to Crown’s tough, durable standards therefore no other battery performs, or lasts, like a Crown. As tough as you can get because tough means long-lasting. Dependable, long-lasting, heavy duty: Crown.
Severe Duty Battery
The Severe Duty Batteries integrate the benefits of a cyclic battery design with maintenance-free calcium plates to provide superb performance and reliability. Crown’s Severe Duty Batteries perform under the most grueling and harsh conditions where other 
batteries stop. Cold. Because you operate in these conditions, Crown builds the battery for you! Crown’s advanced technology has combined the essential characteristics of a high performance battery – with the endurance features you’ve come to expect from Crown – into one incredibly tough battery that is like no other.
