It also provides guidance on safely and effectively configuring, and operating ALM 12V7 s-Series batteries as building blocks in various applications. The ALM 12V7 s-Series batteries are identical in size to common 7Ah, volt, lead-acid batteries and designed to be compatible with most lead-acid chargers. It can:. Overview ALM 12V7 s-Series batteries are compliant with, or tested to, the following regulatory standards:.

This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions:. Environmental Regulations ALM 12V7 s-Series batteries are compliant with the following applicable environmental regulations. Transporting Lithium-Ion Batteries The material presented in this guide is not all-inclusive of the regulations required to ship a product, but is meant to inform you of the complexity involved in doing so.

The information contained herein is for informational purposes only and is not legal advice or a substitute for legal counsel. Anyone involved in the integration of lithium-ion battery packs into a host product must review and meet the regulations cited in this guide.

Additionally, the regulations discussed in this guide apply to lithium-ion cells and batteries. Once an ALM 12V7 s-Series battery is integrated into a host product, the host product may be subject to additional transportation regulations that require additional certification testing.

Refer to Table 3 on page 14 for a list of proper names and UN numbers required for shipping lithium-ion batteries. Regulations Overview Rechargeable lithium-ion including lithium-ion polymer cells and batteries are considered dangerous goods.

Transport of dangerous goods is regulated internationally by:. Refer to the following sections within 49 CFR for specific information. As a class 9 material, cells and batteries must meet UN testing and packaging requirements as well as shipping regulations. Following International and U. Table 2 outlines an example process to help ensure that batteries are shipped per the required regulations.

Ship the battery pack to a UN 2A Pack per regulations and per packaging manufacturer's instructions. Insure that packaging container has all the required labeling. Table 3 lists 5 Mark and label the package. Fill out the shipping 6 documentation. Complete shipper's declaration for dangerous goods, airway bill, etc. Ensure that shipping company can ship dangerous goods and that a Safety 7 Ship the package.

Data Sheet or equivalent document and any Competent Authority Approval accompanies the package. Proper Shipping Name Description. Lithium ion batteries UN Lithium ion batteries packed with equipment UN Lithium ion batteries contained in equipment UN 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.

Reduce charging limits for lower operating temperatures for longer life of the batteries. The advanced design of the ALM 12V7 s-Series is intended to provide protection against operation under many unsafe conditions such as over voltage, under voltage, over temperature and short circuit. The ALM 12V7 s-Series battery case, including its top cover is capable of sustaining a mounting force of up to Newtons spread over a one-inch-wide 2. Exertions beyond this level may result in deforming of the plastic.

Table 11, on page 31, provides guidance on the conditions under which the battery may encounter internal thermal or external terminal touch temperature limits. In a battery system, cable. Contact NEC Energy Solutions Technical Support for assistance in determining appropriate wiring and bus bar configurations to address current sharing and stray inductance requirements.

Using the batteries directly with DC motors can permanently damage the battery. They are intended to mate with standard female 0.

Attach cable by inserting connector fully until the round locking detent has engaged the center hole. Configuring Batteries in Series Strings To achieve higher operating voltages, arrange the ALM 12V7 s-Series batteries in series strings by connecting the positive terminal of one battery to the negative terminal of the next battery, as shown in Figure 3.

NOTE The following battery string wiring examples provide general configuration information. Actual wire configurations must be evaluated for their particular application. To ensure even loading, make two star connections; one for the positive battery terminals and one for the negative battery terminals.

The cable lengths in each star group should be of approximately equal measure as permitted by the physical layout. From each star connection, use a twisted pair of cables to the load. Bus bar connections are recommended for current exceeding amps.

The nominal capacity for the parallel group can be calculated by multiplying the number of batteries in the group by 5 Ah. The maximum supported array is 4S10P. When designing and constructing any series-parallel battery combinations, contact NEC Energy Solutions Technical Support for assistance in determining appropriate wiring and bus bar configurations to address current sharing and stray inductance requirements.

When a battery or battery group is connected to a heavy duty charger, external capacitance may need to be added to the circuity to address the output inductance of the charger. The CV2 of the attached capacitor should be larger than the LI2 of the charger. The charger inductance is the sum of the internal and external inductances.

It remains the end users responsibility to certify their own unique solution. L'inductance de charge est la somme des inductances internes et externes. Refer to Table 5, on page 24 for environmental specifications. Specification Description. Nominal Operational Voltage Minimum Operational Voltage 8. Recommended Float Charge Voltage Nominal Capacity 5 Ah. Minimum Capacity at BOL 4. Continuous current charge or discharge is defined as occurring over a single full-charge or full-discharge cycle.

Environmental Specification Description. Maximum Operational Altitude 15, ft a. The maximum operating temperature decreases by a factor of 1. See Shelf Life on page ALM 12V7 s-Series batteries have been tested to Tension fonctionnelle nominale 13,2 volts. Altitude fonctionnelle maximum 15, pieds m "a. Dimensions excluding terminals x ALM 12V7s: g 2.

Dimensions sans les bornes de connection x 64,5 x 99,7 mm 5,9 x 2,5 x 3,9 in. When this occurs, active sources like power supplies and battery chargers can create large transient spikes.

External energy absorption devices like capacitors or clamps can reduce the overshoot or stress on the battery and may be required based on the application.

Over Current Protection The ALM 12V7 s-Series batteries apply a time-based current limit profile that allows higher level current pulses for short durations. These current limit profiles apply to both charge and discharge operations.

Exceeding the A peak current will result in NO charge. The battery is considered fully discharged when one of its internal cell voltages falls to 2.

In such a case, one cell may activate the UVP protection before the others do. When this happens the voltage measured at the battery terminals will be higher than 8 volts.

Table 10 on page 30, shows the voltage at which a battery could enter UVP and open the terminals. NOTE Under voltage protection creates an open circuit, removing voltage from the terminals.

With a lead- acid battery, finding no voltage at the terminals often indicates the battery is no longer usable. With the ALM 12V7 s-Series battery, no voltage at the terminals typically means the cell protection circuitry has interrupted current to protect the battery.

Simply connect the battery to a charge source to restore voltage to the terminals. Smart Charger Support Smart charger technologies require the presence of a terminal voltage before supplying a charge current.
