Product Information

EM–SSEERRIEIESS AGM155/180

The Stryten Energy AGM155 and AGM180 are 12 volt, valve
regulated lead acid (VRLA) stationary batteries. These batteries
are designed for energy storage purposes and should be handled,
installed, operated, and maintained with caution. The batteries
contain lead and sulfuric acid electrolyte, which can cause burns
and serious injury if mishandled. Safety precautions must be
followed at all times to ensure safe usage.

Safety Precautions

Warning: Risk of fire, explosion, or burns. Do
not disassemble, heat above 50 degrees Celsius, or incinerate.
Personnel working with the batteries should wear protective
gear such as a rubber apron, rubber gloves, and eye
protection.
The batteries generate explosive hydrogen gases under certain
operating conditions. They should be stored and operated in a
well-ventilated area. Sparks, flames, and smoking materials must be
kept away from the battery area.
Before working on batteries or charging equipment, the AC and
DC circuits should be disconnected.
Legacy Marathon FT and Stryten Energy AGM155 or AGM180
batteries should not be mixed within a series connected string.
However, parallel connected strings of Legacy Marathon FT and
Stryten Energy AGM155 or AGM180 are acceptable.

Storage

The batteries should not be stored for extended periods without
proper charge, as this can result in excessive sulfation of plates,
which is detrimental to battery performance and life.

Charging

If the Stryten Energy AGM155 or AGM180 battery is fully
discharged or has an Open Circuit Voltage (OCV) less than 12.30VDC,
it should be recharged using a constant voltage charger set to 2.40
volts PER CELL (VPC) for 72 hours OR set to float voltage for 168
hours.
The recharge current should not exceed 54 amps for AGM155 or 63
amps for AGM180.
The temperature corrected charge voltage (V corrected) should
not fall below 2.21 VPC or exceed 2.40 VPC.

Installation

For non-central office or customer premises installations, the
battery system installation must follow the National Electrical
Code (and/or applicable international, federal, state, local
electrical codes) along with the information contained in the
Instruction Manual.
If the batteries are being installed in a network
telecommunication facility as part of a centralized power system,
they must be grounded to the Central Office ground system as
appropriate for that facility.
Connector torqueing should be done after cleaning contact
surfaces. All connectors should be installed hand tight initially
to allow for final alignment of 12 volt battery blocks. Once final
alignment is made, all connections should be torqued to the value
shown on the battery.

Inspection Reports

It is recommended to complete a set of annual readings on
individual battery voltage, battery string voltage, and ambient
temperature.

BASIC INSTALLATION AND OPERATION MANUAL FOR
AGM155 and AGM180 LEAD ACID BATTERIES

EM–SSEERRIEIESS
AGM155/180

1.0 GENERAL INFORMATION
The Stryten Energy AGM155 and 180 are 12 volt, valve regulated lead acid (VRLA) stationary batteries. Personnel handling, installing, operating, and maintaining this energy storage device should read and review all safety precautions prior to unpacking.
2.0 SAFETY PRECAUTIONS
2.1 Warning: Risk of fire, explosion, or burns. Do not disassemble, heat above 50 degrees Celsius, or incinerate.
2.2 Stryten Energy AGM155 and 180 contains lead and sulfuric acid electrolyte which can cause burns and/or other serious injury.
2.3 Under certain operating conditions, Stryten Energy AGM155 and 180 will generate explosive hydrogen gases. Store and operate batteries in a well-ventilated area. Keep sparks, flames, and smoking materials away from the battery area.
2.4 When working with batteries, wear rubber apron, rubber gloves, and eye protection.
2.5 All installation tools should be adequately covered with vinyl electrical tape or suitable non-conducting material.
2.6 Disconnect the AC and DC circuits before working on batteries or charging equipment.
2.7 Do not mix Legacy Marathon FT and Stryten Energy AGM155 or 180 batteries within a series connected string. Parallel connected strings of Legacy Marathon FT and Stryten Energy AGM155 or 180 are acceptable.
3.0 STORAGE
3.1 It is recommended that batteries be stored indoors in a cool [25°C (77°F)], clean and dry location.
3.2 The storage interval between the date of shipment and the date of initial charge should not exceed six (6) months @25°C (77°F); or (4.5) months @ 30°C (86°F); or three (3) months @ 35°C (95°F).
3.3 Storage beyond these periods without proper charge can result in excessive sulfation of plates which is detrimental to battery performance and life.
4.0 CHARGING
4.1 Charge (e.g. initial, boost, equalize, refresh) Marathon FTX after an extended time in storage at 2.40 Volts Per Cell (VPC) for 24 hours.

4.2 If the Stryten Energy AGM155 or 180 battery are fully discharged or OCV is less than 12.30VDC, recharge using a constant voltage charger set to 2.40 volts PER CELL (VPC) for 72 hours OR set to float voltage (see 4.3-4.4 below) for 168 hours. For alternate recharge profiles reference Stryten Energy document SE2006. Note: Recharge current should not exceed 54 amps for AGM155 or 63 amps for AGM180.
4.3 Recommended FLOAT (e.g. standby) voltage range for Marathon FTX at 77°F (25°C) is 2.25 to 2.30 Volts Per Cell (VPC).
4.4 For all other temperatures other than 77°F (25°C) the following formula can be used to determine the temperature corrected voltage per cell for float and equalize charge conditions:
V corrected = V25°C-[(Tactual-25°C) x ((.0055)] OR
V corrected = V77°F-[(Tactual-77°F) x ((.003)] Note: Temperature corrected charge voltage (V corrected) should not fall below 2.21 VPC or exceed 2.40 VPC.
5.0 INSTALLATION
5.1 For non-central office or customer premises installations, the battery system installation must follow the National Electrical Code (and/or applicable international, federal, state, local electrical codes) along with the information contained in the Instruction Manual.
5.2 Batteries being installed in a network telecommunication facility as part of a centralized power system must be grounded to the Central Office ground system as appropriate for that facility. The required grounding shall consist of connecting the return side to the Central Office grounding system.
5.3 Connector Torqueing
5.3.1 After cleaning contact surfaces, install all connectors hand tight to allow for final alignment of 12 volt battery blocs. Once final alignment is made, all connections should be torqued to the value shown on the battery.
6.0 INSPECTION REPORTS*
Complete a set of annual readings on individual battery voltage, battery string voltage, and ambient temperature.
