Can lead-acid batteries be dropped
Lead acid cells and battery packs can be recovered from 0V and used with almost the same performance as before. However, lithium-ion cells are too sensitive to over-discharge to be recovered from 0V and used in most applications, and cannot be serviced. To recover a lead acid battery, charge it for 10-12 hours and then measure the terminal voltage. - Download [PDF]

Is a battery healthy if drops under 10 volts with load?
A bad battery can show a false voltage when it has surface charge, this occurs for a length of time after a battery has been charging.
