1769-BA Allen-Bradley CompactLogix Battery Module
1769-BA Product Introduction
The 1769-BA battery module comes from the Allen-Bradley CompactLogix series. Engineers use this lithium battery to maintain critical data inside compatible controllers. Specifically, it keeps the user program, configuration settings, and program data alive when the controller loses external power. This model works with both Series A and Series B systems. Additionally, it supports controllers like 1769-L23E-QB1B, 1769-L32E, and 1769-L35E.
1769-BA Technical Specifications
The 1769-BA operates with a nominal output voltage of 3.0 VDC and a nominal capacity of 850mAh. Its continuous isolation voltage reaches 30 volts. The backplane current is 1.4 amps at 24 volts. Furthermore, power consumption is rated at 33.6 watts, while power dissipation stays at 7.5 watts.
This battery uses a cylindrical SE Type cell. Manufacturers Sanyo and FDK produce it. The cell dimensions are 0.58 inches in diameter and 1.04 inches long. Wire leads are included for fast connection to the controller's circuitry.
Mechanical and Environmental Data
The 1769-BA has an open enclosure design. This structure promotes better airflow and heat dissipation. Its shipping dimensions are 8 x 8 x 5 inches (203 x 203 x 127 mm). The module itself is lightweight at only 2 pounds.
For storage, keep the battery in a well-ventilated, dry, and cool area. Avoid direct sunlight, water, condensation, rain, snow, and frost. Also, stay away from heat sources or hot air nozzles.
Installation Guidelines
Important: Replace the 1769-BA only while the controller receives active power. This practice ensures that the controller's memory retains all data through the active power supply.
If you remove the lithium battery when the controller is powered down, you risk losing all stored data in volatile memory. Therefore, always keep power applied during replacement.
The controller only uses the 1769-BA when shutdown or external power is removed. However, if your system uses a non-volatile Secure Digital (SD) card or CompactFlash card, you may remove the battery even during shutdown. Without these memory modules, avoid doing so.
Note that the 1769-BA does not retain data on SD cards or CompactFlash cards.
Battery Status Indicator
Controllers provide a BAT indicator to monitor charge levels. When the BAT LED activates, it signals that battery charge is nearing depletion. Typically, you have a few days or up to two weeks from the first activation. Consequently, replace the battery as soon as possible.
Compliance and Safety
The 1769-BA meets exemption rules for dangerous goods. It complies with US DOT 49CFR 173.185, IATA Packing Instruction 968 Section II, ADR 188, and IMDG 188.
Never short-circuit, disassemble, deform, heat, or incinerate this battery. Do not pile up or mix different batteries together. Avoid placing batteries on metal cases, plates, or antistatic materials.
For multi-cell applications, replace all old batteries with new ones at the same time.
Composition and Disposal
The positive electrode uses Manganese Dioxide. The negative electrode consists of Lithium metal. The electrolyte contains Lithium perchlorate, 1,2-Dimethoxyethane, and a mixture of organic solvents.
Dispose of removed batteries according to local directives.
Packaging List
No certificates or warranty documents are included.
Shipping Methods
We ship via FedEx, UPS, and DHL to ensure fast and reliable delivery.
Frequently Asked Questions (FAQ)
1. Which controllers work with the 1769-BA?
The 1769-BA is compatible with 1769-L23-QBFC1B, 1769-L23E-QB1B, 1769-L23E-QBFC1B, 1769-L31, 1769-L32C, 1769-L35CR, 1769-L32E, and 1769-L35E controllers.
2. How do I know when to replace the 1769-BA?
The BAT LED on the controller lights up when the charge is low. You should replace the 1769-BA within days or a couple of weeks after this warning appears.
3. Can I remove the 1769-BA while the controller is off?
It is not recommended unless an SD or CompactFlash card is installed. Otherwise, removing the 1769-BA without power may erase all volatile memory data.
4. Does the 1769-BA support SD card data retention?
No. The 1769-BA only retains data in the controller's volatile memory. It does not back up SD cards or CompactFlash cards.
5. How should I store spare 1769-BA batteries?
Store them in a cool, dry, well-ventilated area away from sunlight, water, and heat sources. Avoid condensation and frost.
