1. REVISION HISTORY 2. INTRODUCTION
2.1 Scope
This specification describes the physical, functional and electrical
characteristics of a rechargeable Lithium Ion battery SE-2034 by
Sealed Energy Systems (SES®). This specification is the interface
document between SES® and its customers. It is understood that
the customer may create their own internal specification. However,
this specification is the master that defines the battery’s operation.
2.2 Battery Pack Overview
This specification describes the physical, functional and electrical
requirements for the SE20403NR29 Smart Battery including a
rechargeable Lithium Ion battery and a Battery Management Module.
The battery consists of twelve (12) Lithium Ion rechargeable cells of
INR-18650 size, assembled in a 3 series/ 4 parallel (3S4P) configuration.
Each cell has an average voltage of 3.6V and a typical capacity of
2.85Ah giving a battery pack of 10.8V and 11.4Ah typical.
The battery is capable of communicating with host or the charger
through the System Management Bus (SMBus). The battery is fully
SMBus and SBDS Revision 1.1compliant. Protection is provided for
over-charge, over-discharge and short circuit. For redundancy,
passive safety devices have been integrated into the pack to protect
against over- current and over-temperature, and secondary
overvoltage has been implemented with a logic-fuse and controller.

2.3.4 Disposal
Regulations vary for different countries. Dispose of in
accordance with local regulations.
Intact, spent batteries are not considered to be hazardous
waste.
Waste Treatment Methods: Waste Li-Ion batteries meet the
United States federal definition of a solid waste per 40 Code
of Federal Regulations (CFR) 261.2. It is recommended that
the batteries be recycled even though they can be disposed
of in the garbage.
Recycling: Waste Li-Ion batteries do not fall under any
specific RCRA, F, K, P or U lists. The status of scrap Li-Ion
batteries should be confirmed in the nation or US state
where disposal occurs.
2.3.5 Comply with Waste Regulations:
India: Expended battery must be taken for recycling or
disposal at an appropriate collection depot by suitably
licensed contractors in accordance with state and center
government regulations.
USA: Expended batteries are not considered hazardous
waste. Cells and batteries involved in a fire may be
considered to be hazardous waste. Dispose of in
accordance with local, state and federal laws and
regulations. Consult universal/hazardous waste
regulations for further information regarding disposal
of spent batteries. If the internal cells are
leaking/broken open, consult hazardous waste
regulations under US Environmental Protection
Agency’s Resource Conservation and Recovery Act
(RCRA), waste code: D003(reactivity). Also, consult state
and local regulations for further disposal requirements.
Canada: Expended battery packs are not considered hazardous
waste. Cells and batteries involved in a fire may be
considered to be hazardous waste. Dispose of in
accordance with local, provincial and federal laws and
regulations. Consult the Canadian Environmental
Protection Act for additional details.
EU: Expended battery pack waste must be disposed of in
accordance with relevant EC Directives and national,
regional and local environmental control regulations.
For disposal within the EC, the appropriate code
according to the European Waste Catalogue (EWC)
should be used. EU Waste Code: 16 06 05 –other
batteries and accumulators.
Australia: Expended battery packs must be taken for recycling or
disposal at an appropriate collection depot by suitably
licensed contractors in accordance with government
regulations.
