SWL series valve regulated lead acid batteries are an enhanced NPL design resulting in an improved energy to density ratio, giving up to 40% extra discharge capacity. All other attributes and operational characteristics are the same, thereby maintaining the benefit of a common mechanical and electrical design for users of both products. SWL Series are the ideal choice of battery for uninterruptible power supply (UPS) and high rate discharge applications.
