Problem

Service is aware of an accessory issue that affects proper Battery Metering when
using some SNN5683A batteries. The SNN5683A batteries, manufactured with
LiShen E14 cells, were programmed with incorrect metering values. Relevant
batteries will show the wrong steps on meter during discharge.
discharge should be shown on the battery meter according first column below,
but the problematic batteries show different behavior (most time on 1 bar).
Customer will notice batteries transition early from 3 to 2 bars, and 2 to 1 bar,
which may be interpreted as “Short Battery Life”.

Intended Programming Faulty Programming

3 Bars – 100% - 45% left 3 Bars – 100% - 69% left
2 Bars – 45% - 20% left 2 Bars - 69% - 54% left
1 Bar – 20% - 5% left 1 Bar - 54% - 3% left
Low Battery Warning: below 5% left Low Battery Warning: below 3% left

directly beside the battery part number. See Image Below.

Example: SNN5638A G6UU40CTOEJG.FI

Impacted Cell Date Codes: OEH – PAF

Good Cell Date Codes: PAG and later

The Cell Date Code can be used to identify 6U cells that were manufactured
during the relevant timeframe WW47 ’04 thru WW05 ‘05. These are the
characters 9-11 on the battery’s date code which is directly beside the battery
part number. See Image Above.

Solution

All internal inventories of the SNN5683A battery have been separated in the
distribution centers. A total of 263K affected batteries were identified after
screening from all locations. This was completed on 3/9/2005. All concerned
material has been purged. Re-Programming of the affected batteries was
determined not to be a cost-effective solution.
