What you should NOT do 

Avoid only giving short partial charges of 2 or 3 hours regularly, as this reduces battery lifespan. 

Never push your scooter or wheelchair to its maximum performance constantly; this strains the batteries. .

Don’t leave the batteries uncharged for more than a month. 

Never use your wheelchair or scooter until the battery is completely drained. 

Do not use chargers that are not recommended by the manufacturer. 

The less the battery is discharged between charges, the longer its lifespan will be. 

Never leave batteries discharged indefinitely.
