Hi Daz, yeah it will do that on a fully charged pack as the discharge rate is usually a lot lower than the charge rate usually 1 or 2 amps, best to run it down in a car for 5 minutes and then it stick on storage mode from there. There is a specific storage mode on most chargers rather than using the discharge cycle this usually balances the cells at 3.8v each as well so you don't get one cell at 4.6v and one at 3.2v which would mean it's close to not charging again
