All batteries supplied with the scooters / powerchairs we sell are of the sealed type and DOT / IATA approved for air travel. Certificates can be obtained from the manufacturer on request.
If you use your scooter outside of your home every day, then it should be charged every day. If you use it less frequently then always charge your batteries before an outing, or after active use. Use the 3:1 ratio as a guide; one hour of use requires 3 hours of charging. Avoid "topping-off" your batteries with frequent charging, but never run your battery completely flat. Always read your Owner's Manual.
If you stop using your scooter/powerchair for an extended period of time, disconnect your batteries and then check them once a month and recharge if necessary. Always store your batteries fully charged. Avoid hot and cold extremes of temperature.
