The Tadiran SL-750/S 3.6V 1/2AA is a high-capacity, non-rechargeable lithium thionyl chloride cell delivering 1100mAh in a compact 1/2AA form factor. Designed for demanding industrial and OEM applications, it operates reliably from -55°C to +85°C, offers minimal self-discharge and an expected shelf life of up to 10 years. With a low typical drain of 1 mA and capability for short pulses up to 100 mA, the SL-750/S is ideal for memory backup, utility metering, remote sensors, security systems, and other long-life devices deployed across the UAE and regional markets.

How to install and maintain the Tadiran SL-750/S 3.6V (1/2AA) battery

Step 1 — Verify Compatibility
Confirm the device lists 3.6V 1/2AA primary cells and that the SL-750/S matches the cell size and terminal orientation. Check device datasheet for recommended maximum continuous and pulse currents.

Step 2 — Power Down the Device
Before replacing the cell, power down the equipment and, if possible, disconnect any external supply to reduce risk of short or data corruption.

Step 3 — Observe Polarity
Identify the positive (+) and negative (–) terminals on both the battery and device holder. Insert the SL-750/S with correct polarity. Polarity reversal can damage electronics and the battery.

Step 4 — Secure Fit & Contact Points
Ensure the cell sits snugly in its holder and that contact springs or pads are clean and free of corrosion. Poor contact can cause voltage drop or intermittent failures.

Step 5 — Initial Power-Up & Test
Power the device and run an initial self-test or diagnostics. Verify expected voltage and check for any error indicators. For devices with data backup, validate that memory retention is intact.

Step 6 — Monitor in Early Operation
After replacement, monitor the device for a short period to ensure normal operation. If device performs erratically, re-check terminal contact and install orientation.

Step 7 — Maintenance & Troubleshooting

• If the device shows low battery warnings shortly after replacement, re-check polarity and contact; consider that prolonged storage or extreme temperatures may have affected battery performance.

• For rapid voltage drop under load, confirm that the application’s average and pulse currents are within SL-750/S specifications. If not, redesign power profile or select a higher-drain solution.

• If battery heating occurs, remove battery immediately and inspect device for short circuit.

Safety Notes:
Do not short-circuit, puncture, or incinerate the cell. Do not attempt to recharge. Store unused batteries in original packaging and recycle used cells per local regulations.

This guide helps ensure correct installation and long service life of the Tadiran SL-750/S in your equipment.

Q1: Is Tadiran SL-750/S rechargeable?
No. The Tadiran SL-750/S is a non-rechargeable lithium (thionyl chloride) cell. Attempting to recharge it may damage the battery and create a safety hazard. It’s intended as a primary cell for long-term, low-drain applications and must be replaced when depleted. For rechargeable needs, select a designated rechargeable chemistry (Li-ion, NiMH) engineered for repeated charge cycles.

Q2: What is the typical lifespan of a Tadiran SL-750 battery?
In storage, Tadiran cites a shelf life up to 10 years with minimal self-discharge. In service life depends on duty cycle: low continuous drains (≈1 mA) yield many years of operation, while frequent high-current events shorten life. Exact lifetime depends on application current profile, temperature, and pulse frequency. For accurate estimation, supply your device’s average and peak current profiles to verify expected run-time.

Q3: What devices commonly use the SL-750/S 3.6V cell?
Common applications include utility meters, memory backup modules, telemetry sensors, security & alarm systems, and industrial controllers. The cell is chosen where long shelf life, wide operating temperature, and reliable low-drain performance are priorities — typical of remote or hard-to-service installations.

Q4: Can the SL-750/S handle pulse currents and wireless transmissions?
Yes — the cell supports short pulse currents (maximum forward impulse around 100 mA) for brief transmission bursts. However, frequent high-current pulses will accelerate capacity loss. It’s recommended to evaluate the device’s duty cycle and ensure average current stays within Tadiran’s recommended continuous limits to meet the intended service life.

Q5: How should I store and dispose of these batteries?
Store SL-750/S cells in a cool, dry place away from direct sunlight and high heat. Avoid storing with metallic objects that could short terminals. For disposal, follow UAE and local electronic-waste regulations — lithium cells should be recycled through authorised e-waste or battery collection programs; do not incinerate or dispose in regular waste.
