LS14500STD is a non-rechargeable SAFT LS 14500 lithium cell in AA size, with a voltage of 3.6 V and a capacity of 2.6 Ah (2,600 mAh). It is supplied without cables, a connector or solder tabs. It is intended for suitable low-current devices requiring memory backup.
Need to confirm the correct battery configuration?
Send a photo of the original battery and device nameplate, and of the connector if applicable. We will confirm availability and the delivery date.
Battery application
In the FOXON range, it is intended for the corresponding Allen-Bradley, SIEMENS SIMATIC S7-400, SIMATIC S5-101/115 and Modicon devices. When main power is lost, it supplies the backed-up memory circuits in the applicable devices. Confirm the exact application against the particular CPU, power supply module or battery holder; the PLC series alone does not determine the correct configuration.

Overview of replacement and related designations
These designations help identify a replacement. Some refer to the cell alone, while others refer to a complete battery assembly. Before ordering, compare the electrical specifications, holder, terminals and any connector; the list does not confirm that all configurations are directly interchangeable.

STD means a standalone cell without leads. Before selecting a replacement, compare the voltage, chemistry, size, contacts and polarity of the original battery. If the original battery has cables, a connector or solder tabs, you need the corresponding assembly. Capacity depends on current draw, temperature and cut-off voltage, rather than just the number on the label. Use the maximum cell dimensions to check the space in the holder. Do not solder directly onto the cell body.
Scope of delivery
One SAFT LS 14500 cell without a cable, connector or holder.
Frequently asked questions about PLC backup batteries
What does a backup battery do in a PLC?
In battery-backed PLCs, it retains the contents of selected RAM areas when the main power supply is off. Depending on the CPU design, this covers the program, current data values or operation of the real-time clock. The particular CPU and its configuration determine what is backed up. The battery does not power normal PLC operation or its inputs and outputs.
Does every PLC need a backup battery?
No. Some CPUs retain the program and selected data without a replaceable battery. The memory architecture and exact CPU order number are decisive, rather than the series name alone. Check the documentation and battery compartment of the particular device before ordering.
How often should the battery be replaced?
Follow the preventive replacement interval specified by the manufacturer of the particular PLC. Service life depends on the current drawn by the backed-up circuits, time without main power, temperature and battery age. Record the installation date and include replacement in the maintenance plan. Capacity alone does not determine the number of years in service; there is no universal interval for all PLCs.
How do I recognise a low or faulty battery?
Depending on the CPU type, a fault is indicated by an indicator light, diagnostic message or status available in the programming software. Check the exact meaning of the indication for the device: a missing battery or connection problem may also be the cause. The indication does not reliably show the remaining backup time. First ensure that the data is backed up and resolve the fault before a planned power shutdown.
What happens if I do not replace a depleted battery?
If main power is also lost, the contents of battery-dependent memory areas may be lost or the real-time clock may stop. Depending on the CPU and memory used, the program, current data values or some of them may be lost. Battery depletion alone does not erase non-volatile memory. However, losing current data makes restarting the machine more difficult.
How do winter conditions and low temperatures affect the battery?
As temperature falls, the internal resistance of lithium cells increases and their voltage under load and usable capacity decrease. The actual battery temperature inside the device is decisive. Cold conditions therefore reduce the backup margin, especially for an older battery. Observe the temperature limits of the cell, complete battery assembly and PLC together; a wide temperature range for the cell alone does not mean that the entire device has the same tolerance.
Does high temperature shorten battery life?
Yes. In lithium backup cells, high temperature accelerates self-discharge and affects their ability to supply the required current. When planning maintenance, take account of the temperature inside the control cabinet and the storage conditions for spare batteries. Nominal capacity measured at room temperature does not guarantee the same service life in a hot control cabinet.
Should the battery be changed with the PLC powered on or off?
The manufacturer of the particular CPU specifies the procedure. For some battery-backed PLCs, main power must remain on during replacement to prevent data loss. This procedure cannot be applied to all controllers. Before disconnecting the battery, check the specified power state, CPU mode and machine service conditions.
What should be checked before and after replacement?
Before replacement, check that a usable backup of the program and required data is available, and check the new battery designation, connector and polarity. Record the diagnostic status and prepare the work according to the device service procedure. After replacement, check the battery indication, diagnostics and required CPU state. If the clock or operating values are backed up, check them too. Record the date and type of battery installed in the maintenance log.
Is the same voltage enough when selecting a replacement?
No. Also compare the chemistry, dimensions, capacity required by the device, connector, wire connections and polarity. The same connector with different wiring is not a suitable replacement. Do not replace a battery with connecting leads with a standalone cell without checking the complete configuration. For LS14500STD, check whether you need a standalone AA cell for a holder or a battery with cables and a connector.
Can I determine the remaining service life by measuring voltage?
Open-circuit voltage alone does not determine remaining capacity. In Li-SOCl₂ cells, voltage changes very little through much of the discharge; temperature and load also affect the result. Use device diagnostics and the battery manufacturer’s procedure to assess its condition. An open-circuit measurement does not replace preventive replacement.
How should a spare primary lithium battery be stored?
Keep it in its packaging, in a cool, dry place under the manufacturer’s specified conditions. Protect the poles and any leads from short circuits, and keep track of the battery designation and age. A primary lithium battery is not rechargeable: do not connect it to a charger, short-circuit it or solder directly onto the cell body. Use a suitable ready-made version with the required terminals.
Can I use LS14500STD directly in place of a battery with a connector?
The LS14500STD cell alone does not include cables or a connector. It can be inserted directly only into a suitable holder for a standalone cell. If the original battery is part of a wired assembly or has solder tabs, request the corresponding assembly using a photo and the designation of the original battery.
