NEC Energy Solutions announced the availability of its new generation ALM™ 12V7s product line of 12-Volt, 5 Amp-hour batteries that offers higher power, longer life, and robust safety compared to comparable lead-acid batteries or other lithium-ion products. The ALM 12V7s line builds upon the success of the earlier generation ALM 12V7 with additional capabilities including high current discharge, smart charger detection, and EverSafe™ battery protection technology, which provides immunity to short circuit, over voltage, under voltage, and other common accidental battery abuse conditions. In addition, system scalability is improved through support of self-balancing battery arrays of 24V, 36V, or 48V and up to 10 units in parallel for 50Ah capacity, with no additional BMS devices necessary.

The ALM 12V7s batteries are dropin alternatives to common 12-Volt, 7Ah lead acid batteries. They deliver high power discharge rates (up to 45A) with minimal reductions in nameplate capacity, making them ideal for short duration industrial uninterruptible power supplies (UPS), and deep cycling applications such as weak and off-grid power systems.

The exceptional cycle and float life, high power performance and unparalleled safety features fundamentally change how power system developers may design, service, and support battery back-up systems. The key benefits of the ALM 12V7s batteries include: Up to twice the usable energy at fast discharge rates, reducing by up to 50% the number of similarly sized batteries required for high power applications. Charging rates up to 100X faster than lead-acid batteries and 2-10X faster than other lithium-ion solutions enable systems to remain in service longer, which reduces the total cost of ownership (TCO) and eliminates the need for oversizing that is typical for lead-acid systems that may not be fully recharged before the next grid outage.
These batteries operate from -40 to 60 degrees C, dramatically outperforming lead-acid batteries in harsh outdoor applications. They offer up to 5X longer calendar life significantly reduces service costs from frequent replacement of lead acid batteries, especially in remote and hard to reach installations. And they are fully integrated, redundant safety systems using NEC Energy Solutions’ EverSafe™ battery protection technology provide multilayer protection at the cell, battery and system level, making the ALM 12V7s among the safest batteries in the industry.

“The ALM 12V7s batteries are compact and light weight and deliver exceptionally high power. Along with a long cycle life and robust safety, they are ideally suited for small cell telecommunications and industrial UPS applications. With this and the previously released ALM 12V35 product line, we are developing a world-class family of 12V lithium ion products designed for the toughest applications,” said Bud Collins, CEO of NEC Energy Solutions.
The ALM 12V7s product line provides the flexibility of two power level models to meet the most demanding applications. They are direct replacements of the first generation ALM 12V7. ALM 12V7s HP is a high power, 45A continuous discharge current battery. It is available now and shipping to initial customers. ALM 12V7s is a nominal power, 23A continuous discharge current battery. It is available for shipment to initial customers later in 2Q 2015.
