These are the common signs stairlift batteries are going bad and should to be replaced
One of the earliest signs that your stairlift batteries may be failing is when the lift starts moving slower than usual or stops and starts intermittently while moving upward. Although other issues could cause similar symptoms, depleted batteries are the most common culprit.
Understanding Stairlift Batteries: Lifespan and Maintenance Tips
Stairlifts are powered by two internal 12-volt DC batteries connected in series to operate a 24-volt DC motor. These batteries are typically Sealed Lead Acid (SLA) and often use Absorbed Glass Mat (AGM) technology to meet the high amperage demands of stairlifts.
The average lifespan of stairlift batteries ranges from 3 to 5 years, depending on factors like usage frequency, stair length, system load, and the lift’s age. If you use your stairlift daily, it’s advisable to replace the batteries every three years at a minimum to avoid unexpected breakdowns.
Regular maintenance and timely battery replacement are key to ensuring your stairlift continues to function reliably.
How to Test, Check, and Replace Stairlift Batteries for Optimal Performance
To ensure your stairlift operates smoothly, it’s essential to properly test, check, and replace its batteries. The most accurate way to test stairlift batteries is by using a load tester. A qualified service technician will use this device to assess battery levels and cell stability before recommending a replacement. Even if only one battery fails the test, it’s advisable to replace both, as the second battery is likely near the end of its life. Replacing both batteries at once can save you the cost of a second service call.
During the service, it’s also crucial to check the charging circuit. The technician will verify the correct voltage from the wall outlet to the rail contacts and mainboard. Stairlift batteries rely on an external power supply and transformer, which can range from 15VAC to 33VDC, depending on the manufacturer. This transformer must supply continuous voltage to keep the batteries charged. The technician will inspect the circuit, verify the voltage, and check the wiring for correct grounding and potential shorting issues.
Why Only a Professional Technician Should Check and Replace Your Stairlift Batteries
Stairlift batteries can fail for various reasons, including age, transformer issues, power supply problems, faulty contacts, wiring defects, circuit board malfunctions, and motor complications. A professional technician with experience in stairlift maintenance can accurately diagnose and fix these problems, ensuring your lift operates smoothly. During the service, the technician can also perform essential maintenance, warranty checks, and a thorough inspection of your stairlift.
It’s crucial to understand that stairlift batteries store a significant amount of power and can pose hazards if not handled correctly. Improper handling can lead to damage or safety risks, making it essential to rely on a professional for battery replacement.
Safe Disposal and Recycling of Stairlift Batteries
Another reason to use a professional stairlift service is the safe disposal and recycling of old batteries. Stairlift batteries, often made from lead-acid or lithium-ion, contain hazardous materials that require careful handling. Professional stairlift companies have the expertise and tools to remove and recycle these batteries safely, ensuring compliance with environmental standards. By choosing a professional service, you contribute to sustainable practices, preventing harmful substances from ending up in landfills and reducing your environmental impact.
