Handheld chargers

Could you use a lower voltage charger to charge a higher voltage tool? For example what would happen if you tried to use a 6 volt charger to charge a 7.2 volt item (assuming the adapter fits)

Generally it will not charge the battery correctly. The charger has to be matched to the battery voltage and chemistry. Depending on the type of battery, the charger will apply a slightly higher voltage than the battery rating for a particular amount of time.

The reason I'm so vague is that you have to charge a lead acid battery much differently than a lithium ion battery for example. It is important that the charger matches the battery or the battery could overheat and explode or be damaged.

The adapter won't fit. Check the amperage as well as the voltage. Chargers are too cheap not to use the correct one.
