The literature defines requirements for resistance in both cell to cell and cell to terminal connections in supplied battery systems. High connection resistance causes increased cell voltage drop and a potential failure to meet run time requirements.

"Internal investigation by Enersys confirms that no defects exist in systems tested before shipment to customer utilities as internal documented procedures define correct parameters. However, the potential of less than desired performance exists if the values noted in the literature are used during installation and test at utility sites.

"Enersys does not have the ability to evaluate if a defect exists at customer utilities so per the provisions of Part 21, notification is being made to both the Commission and affected Enersys customers."

Dear Purchasing Manager,

This letter will serve as notification from Enersys of an identified deviation in published literature information. The literature defines requirements for resistance in both cell to cell and cell to terminal connections in supplied battery systems. High connection resistance causes in.creased cell voltage drop and potentially failure to meet nm time requirements.

The literature in question is the Enersys Safety, Storage, Installation, Operation and Maintenance Manual for Flooded Lead-Acid Batteries C, D, E, F and G, number US-FL-IOM-002 dated January 2007. The errors are located in Section 7.4.3.8c line 2. The current wording of" ... connection is more than 30% or 5 Mohms above the average ...

should read "connection is more than 10% or 5 micro-ohms, whichever is greater, above the average".

Internal investigation by Enersys indicates that no defects exist in systems tested before shipment to customer utilities as internal documented procedures define correct parameters. However, the potential ofless than desired performance exists if the values noted in the literature are used during installation and test at utility sites.

Enersys does not have the ability to evaluate if a defect exists at customer utilities so per the provisions of Part 21, notification is being made to potentially affected Enersys customers.

Please contact me with questions.
