If it is too high then it will overcharge the battery, but you might be able to add a voltage regulator to lower the voltage and limit the current to suit your battery. I'm assuming you're referring to lead acid chemistry. If the voltage (potential) is not greater then no current will flow, therefore it is impossible to overcharge.
If neither the charger nor the protection circuit stops the charging process, then more and more energy enters the cell. As a result, the voltage in the cell rises – this is known as over-charging. On the one hand, this is harmful to the battery and bad for its life span. On the other hand, it can pose a safety risk for the user.
Any battery charger without current limiting can cause problems. Should the battery, (any chemistry) not be in good condition, the voltage will never reach 12V, causing a charger without current limiting to continue to supply current until the battery overheats, as well as the charger.
Should the battery, (any chemistry) not be in good condition, the voltage will never reach 12V, causing a charger without current limiting to continue to supply current until the battery overheats, as well as the charger. Highly active question.
Contrary to what some comments/answers may suggest, the charger needs to be told the maximum current to deliver. They normally don't/can't 'sense' it. The important thing is to use the correct battery charger circuitry based on the chemistry of the battery.
With the aid of very low current, an attempt must be made to rebuild the basic voltage so that charging can then resume normally from 3 V,” says Heydecke. Users must therefore ensure that suitable chargers are used and to avoid damaging the devices and batteries.
For instance, a lithium-ion battery may charge at a constant current of 1C until it comes to around 70% capacity, after which the charger switches to a regular voltage mode, tapering the current down until the charge is complete.
