I have used small motorcycle batteries on them no problems vint_mow, had another one come today $45 pretty good value. I still think you are worrying too much about hitting the starter button, the plastic starter gears are worth peanuts and that is all that would get damaged and you would have to bump it a hundred times to do any damage. The gears are probably a lot cheaper than the switch you just bought
