5. Operating Instructions
5.1 Charging the Batteries
For optimal performance and longevity, always use a charger specifically designed for 12V 75AH Sealed Lead Acid (SLA) batteries. Refer to your ActiveCare Medical Osprey 4410's manual for specific charging procedures and recommended charger specifications.
- Connect the charger to the mobility device's charging port.
- Plug the charger into a standard electrical outlet.
- Allow the batteries to charge fully. Most chargers have indicator lights to show charging status.
- Avoid overcharging, as this can reduce battery life. Disconnect the charger once the batteries are fully charged.
5.2 General Use
- Avoid deep discharges. Recharge the batteries as soon as possible after use, especially if the charge level is low.
- Do not leave batteries in a discharged state for extended periods, as this can cause irreversible damage.
- Operate your mobility device within its recommended temperature range. Extreme temperatures can affect battery performance and lifespan.
6. Maintenance
Proper maintenance can significantly extend the life of your SigmasTek SP12-75 IT batteries.
- Cleaning Terminals: Periodically inspect battery terminals for corrosion. If corrosion is present, clean with a wire brush and a mixture of baking soda and water. Ensure terminals are dry before reconnecting.
- Storage: If the mobility device will not be used for an extended period, fully charge the batteries and store them in a cool, dry place. Recharge them every 3-6 months to prevent self-discharge and maintain capacity.
- Temperature: Avoid storing or operating batteries in extreme hot or cold conditions. The ideal operating temperature is between 68°F (20°C) and 77°F (25°C).
- Physical Inspection: Regularly check the battery casings for any signs of damage, cracks, or swelling. If any damage is observed, replace the battery immediately.
7. Troubleshooting
If you encounter issues with your battery set, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Battery not charging | Charger not connected, faulty charger, loose connections, deeply discharged battery. | Ensure charger is properly connected and plugged in. Check charger functionality. Verify all battery connections are secure. If deeply discharged, a specialized charger might be needed, or the battery may be damaged. |
| Short operating time | Battery not fully charged, aging batteries, excessive load, cold temperatures. | Ensure batteries are fully charged before use. Batteries naturally lose capacity over time; consider replacement if significantly degraded. Avoid operating in very cold conditions. |
| Device not powering on | Batteries not connected, completely discharged, faulty device. | Check all battery connections. Attempt to charge the batteries. If the issue persists, consult your mobility device's service manual or a qualified technician. |
If troubleshooting steps do not resolve the issue, please contact SigmasTek customer support or your device manufacturer.
