You should receive the battery more or less fully charged, though we do recommend charging the battery until it is fully charged, which should be almost instantly. We also recommend charging the battery after every use, and when not in use you should give it a top up charge every month or so. Sticking to this regime will significantly extend the lifespan of your battery ensuring you won’t have to replace it prematurely.
