My battery has started running out AGAIN only a few months after getting it replaced last time. Anyone else had this problem? Is it plausibly just the price I pay for living on top of a really big hill? And if you live in Perth, where do you get yours replaced? I've been using Scooters Australia, which costs about $600 ie RATHER MORE than I'd like to be spending every few months /o\

Have been recharging whenever I'm not using it, trying not to let it run down too low when I'm out, and trying to keep the wheels inflated though we did forget about that for a while. And it's still run out faster than it did before I started doing any of those things.
