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
batteries and designed to be compatible with most lead-acid chargers. This combination
reduces product integration costs, minimizes OEM customer’s time to market and
aftermarket customer replacement hurdles.

ALM®12V7 s-Series Product Line
The ALM 12V7 s-Series consists of the following models:
•TheALM 12V7s is a standard series, base power model. It can:
• Deliver 66 watts for one 1 hour
• Deliver 190 watts for 20 minutes
• Deliver up to 350 watts in one-second pulses
• Be fully charged (from 0 to 100%) in approximately 15 minutes
•TheALM 12V7s HP is a standard series, high power model. It can:
• Deliver 590 watts for six minutes
• Deliver up to 700 watts in one-second pulses
• Be fully charged (from 0 to 100%) in approximately 7 minutes
Each ALM 12V7 s-Series battery has integrated EverSafe™ protection and balancing circuitry
(Figure 2) that safeguard the battery from over‐voltage, under‐voltage, short-circuit and 
over‐temperature conditions. At the core of the ALM 12V7 s-Series are eight A123 Systems®
ANR26650M1B cells in a four‐series, two‐parallel (4S2P) configuration.
