Profile Knight Battery Sales Knight Battery Sales was established in April 1994, in Warrington, Cheshire by myself, Dave Knight. After nearly 10 years in the Industrial Battery industry I was convinced that the battery requirements of the smaller customers were not being properly served. At that time the full benefits of Sealed Lead Acid batteries were becoming apparent but it was the larger users who were dictating both the dimensions and price of these products. There was also a good deal of ignorance and confusion about the different technologies available in Sealed Lead Acid such as Gel, Lead Calcium and Pure Lead. As a result of this I decided to specialise in SLA batteries, offering a range of products to suit the application requirements and by keeping overheads to a minimum, offer the best service and value for money.
