30 Mar Why mobility scooter batteries sulphate & what you can do to prevent it
Note: This applies to AGM Lead Acid Batteries and not Lithium.
A sulfated battery has a buildup of lead sulfate crystals and is the number one cause of early battery failure in lead-acid batteries. The damage caused by battery sulfation is easily preventable and, in some cases, can be reversible. One of the easiest ways to prevent battery sulfation is proper battery storage. When a battery is stored, even if it’s stored at a full charge, a battery must be charged enough to prevent it from dropping below 12.4 volts.
All lead acid batteries will accumulate sulfation in their lifetime as it is part of the natural chemical process of a battery. But, sulfation builds up and causes problems when:
- A battery is overcharged (Hard to prevent without the installation of a battery balancer)
- A battery is stored above 75°F
- A battery is stored without a full charge
To prevent lead acid AGM mobility scooter batteries from sulphating, you can follow these steps:
- Store your scooter in a cool and dry place
- Keep your batteries fully charged when not in use and charge as soon as you get back from a trip
- Avoid overcharging your batteries (Smart battery chargers will stop charging once the batteries reach full charge)
