Introducing the ALM® 12V7 s-Series Batteries

Overview

NEC Energy Solutions’ ALM 12V7 s-Series batteries are the next generation of the ALM 12V7 product line of lithium-ion batteries (Figure 1). ALM 12V7 s-Series batteries are designed as drop‐in replacements for 12-volt, lead-acid batteries. They provide improved performance with

higher power, increased safety and exceptional calendar and cycle life compared to 

12-volt, lead-acid batteries. They typically serve as a standby power source in many  high‐availability and service‐critical applications

The ALM 12V7 s-Series batteries are identical in size to common 7Ah, 12-volt, lead-acid

teries and designed to be compatible with most lead-acid chargers. This combination

bat reduces product integration costs, minimizes OEM customer’s time to market and aftermarket customer replacement hurdles.

Regulations Overview

Rechargeable lithium-ion (including lithium-ion polymer) cells and batteries are considered dangerous goods. The regulations that govern their transport are based on the UN Recommendations on the Transport of Dangerous Goods Model Regulations. Transport of dangerous goods is regulated internationally by:

• International Civil Aviation Organization (ICAO) Technical Instructions

• International Air Transport Association (IATA) Dangerous Goods Regulations

• International Maritime Dangerous Goods (IMDG) Code

In the United States, transportation of hazardous material is regulated by Title (part) 49 of the Code of Federal Regulations or CFR’s. Title 49 CFR Sections 100-185 of the U.S. Hazardous Materials Regulations (HMR) contains the requirements for transporting cells and batteries. Refer to the following sections within 49 CFR for specific information.

• Section 173.185 – Shipping requirements for lithium cells and batteries

• Section 172.102 – Special Provisions

• Sections 172.101, 178 – Further information and specifications on packaging

The Office of Pipeline and Hazardous Materials Safety Administration (PHMSA), which is within the U.S. Department of Transportation (DOT), is responsible for drafting and writing the U.S. regulations that govern the transportation of hazardous materials (also known as dangerous goods) by air, ground, and ocean.

Regulations by Cell/Battery Size

Lithium-ion batteries and cells are considered Class 9, which is one of nine classes of hazardous materials or dangerous goods defined in the regulations. As a class 9 material, cells and batteries must meet UN testing and packaging requirements as well as shipping regulations.

Following International and U.S. DOT Regulations

Failure to comply with International and U.S. DOT regulations while transporting Class 9 Hazardous Materials (Dangerous Goods) may result in substantial civil and criminal penalties.

WARNING

CAUTION

AVERTISSEMENT

Chapter 3: Handling, Storage and Installation

Handling, Storage and Installation

Safety and Handling

ALM 12V7 s-Series batteries are more abuse tolerant than other lithium-ion batteries; however, correct handling and system integration of ALM 12V7 s-Series batteries are still important to ensure safe operation.

Chapter 3

Failure to follow these warnings may result in personal injury or damage to the equipment.

• Do not expose the ALM 12V7 s-Series battery to heat in excess of 60°C during operation or in storage; do not incinerate or expose to open flames.

• Do not connect ALM 12V7 s-Series batteries to batteries of other chemistries or ALM batteries of different capacities. For example, do not connect an ALM 12V7 s-Series battery to any lead‐acid battery or to an ALM 12V35.

Do not charge or discharge an ALM 12V7 s-Series battery outside of its stated operating temperature range. Reduce charging limits for lower operating temperatures for longer life of the batteries.

Ne pas suivre ces avertissements peut entraîner des blessures ou des dommages a l’équipement.

• Ne pas exposer les batteries ALM 12V7 s-Séries à une chaleur dépassant les 60°C pendant son fonctionnement ou son entreposage; ne pas l'incinérer ou l'exposer à des flammes nues.
