Barry,
Even gell is subject to the law of gravity. In both charging and discharging some gas is formed within the electrolyte. The extent of the gas (the pressure) will determine the operation of the vents. If there happens to be gell in front of the vent, then some may be forced out under this pressure. The vent design does not allow this to be forced out of the battery case but with less electrolyte you have a reduced cell capacity. In all but the most extreme cases this is not going to happen, but teams are advised to charge the battery in the upright position so that they can maintain battery health for as long as possible. None of us want to lose a match because our partners battery ran down.
