will 12v charger charge 15v battery

Can a 12V Charger Charge a 15V Battery?

When it comes to charging batteries, it is essential to use the correct voltage to avoid any damage to the battery or the charger. In this case, if you have a 12V charger and a 15V battery, it is not recommended to use the 12V charger to charge the 15V battery. Let’s explore the reasons why and discuss the potential risks involved.

The Importance of Matching Voltage

Batteries are built with a specific voltage rating, which indicates the power level they can store and release. Using a charger with a lower voltage than the battery can result in inefficient charging or even no charging at all. In the case of a 12V charger and a 15V battery, the charging process will not work as intended. The charger may be unable to provide enough voltage to fully charge the battery, leaving it partially charged and potentially unable to function optimally.

The Risks of Using Incompatible Chargers

Using an incompatible charger can pose significant risks to both the charger and the battery. Firstly, the charger may overheat or suffer damage due to the strain it experiences in attempting to charge the battery outside of its voltage range. This can lead to a malfunctioning charger or, in worst-case scenarios, cause a fire hazard.

Furthermore, attempting to charge a battery with a lower voltage charger can result in overcharging and potentially damaging the battery. Overcharging occurs when the charger continuously supplies voltage to the battery, causing it to exceed its safe limit. This can lead to battery overheating, reduced capacity, or even irreversible damage, rendering the battery unusable.

Choosing the Right Charger

To ensure safe and efficient charging, it is crucial to use a charger that matches the voltage requirements of the battery. In this scenario, a 15V charger should be used to charge the 15V battery. It is always recommended to read the manufacturer’s specifications for both the charger and the battery to ensure compatibility. Using the correct charger will ensure optimal performance and longevity for both the charger and the battery.


In summary, attempting to charge a 15V battery with a 12V charger is not advisable. It is essential to use a charger that matches the voltage requirements of the battery to ensure efficient and safe charging. Using an incompatible charger can result in inefficient charging, potential damage to both the charger and the battery, as well as safety hazards. Always read the manufacturer’s specifications and choose the right charger to maximize the performance and lifespan of your battery.
