Hey there! It sounds like your battery might be reaching the end of its lifespan or could have some internal issues causing the decreased performance. Here are a few troubleshooting steps you can try:
Check Connections: Ensure all connections to the battery terminals are secure and free of corrosion. Sometimes poor connections can lead to charging or discharging issues.
Voltage Test: Use a multimeter to measure the voltage of the battery. A fully charged 12V battery should read around 13.2 to 13.8 volts. If it’s significantly lower, it might need to be recharged or replaced.
Load Test: Perform a load test on the battery to see how well it holds up under a load. If the voltage drops rapidly under load, it could indicate a failing battery.
Recharge: If the battery voltage is low, try fully charging it with a suitable charger designed for sealed lead acid batteries. Make sure to follow the manufacturer’s recommendations for charging.
Replacement: If the battery fails to hold a charge even after recharging and other troubleshooting steps, it may be time to consider replacing it.
If you’ve tried these steps and still experience issues, it’s best to consult with a professional technician or contact the manufacturer for further assistance. Let me know if you need any more help!
