FOREWORD

This presentation has been developed as a aid to those wishing to

determine the date of manufacture or warranty date for a cell or

battery. Manufacturers sometimes code dates using letters

and/or numbers that are not easily understood by those

responsible for the battery system. This presentation attempts to

provide those persons with a guide when needed to determine the

date code. Date codes are sometimes changed by the battery

manufacturer and there is no guaranty that the information

needed is contained in the presentation; however, it may help in

ultimately identifying a date code, either with help from the batterymanufacturer or using the information presented to interpret what

one observes. The information contained in this presentation

does not include every battery type or manufacturer.

TERMINAL OBJECTIVE

Upon completion of this training, the participant will obtain:

An overview of the typical methods used by battery

manufacturers to identify the date of manufacture,

warranty or both for stationary batteries

SM

DATE CODES

Are used by battery manufacturers to establish a date ofmanufacture for their products

Some manufacturers have two date codes one representing

the warranty date and the other the manufacturing date

Letters are sometimes used to represent the month or year in adate code

Manufacturers may omit the letters I and O from the

dates codes to avoid confusion with the numbers 1 and 0

Typically, a date code system should not allow the samecharacters to repeat for at least 10 years, based on industry

standards related to date coding

DATE CODES (Continued)

Date codes may be located on the cell (or monobloc) cover orcell (or monobloc) post. For smaller VRLA batteries the date

code may be heat stamped or may be applied by a dot

matrix printer on the side of the cell (or monobloc) cover

If a date code cannot be found, or if found, cannot be

interpreted, one may always contact the battery manufacturer

for guidance. Battery manufacturers may change their date

coding system or may sometimes even reverse the date code,

so if in doubt check with the battery manufacturer.

Battery manufacturers will request the battery date code if awarranty claim is filed

DATE CODES (Continued)

In the presentation, the letters M, D, W and Y, are used to

represent month, day, week and year, respectively

For example MMYYYY, would represent a date code with a

two character month and a four character year and WWYY

would represent a two character week and a two character

year

WHY IS KNOWING THE DATE CODE

IMPORTANT?

It is important to know how old the battery is when inspected,since some of the conditions that may be noted can be age

related and this information will be useful when evaluating the

information gathered during the visual inspection

For example, a large quantity of sediment in a 15 year old

vented lead-acid battery may not be a concern, but the

same amount of sediment in a 2 year old vented lead-acid

battery would be of concern

It is also important to know the date code to determine if awarranty claim can be made

consulted in any case
