Not all battery chargers work with all batteries. There are multiple differences in material composition and electrical capacity between rechargeable batteries, and using the wrong charger can damage the battery, and possibly cause an explosion.

Can you use any charger for AA batteries?

Can Duracell Rechargeable batteries be charged in any battery charger? Yes, in any charger, but Duracell chargers are recommended because they are among the safest in the industry.

How do I know what size battery charger I need?

As a rule of thumb your battery charger should be a minimum of 10% of the Ah rating of the battery. E.g A 100Ah battery would require a 10 Amp charger as a minimum. To prevent overcharging you should keep the charger size to within 20% of the total capacity.

What battery size is AA?

We recommend higher amperage to ensure cooler power supply and optimal charge time. If you get a charger with amperage less than your original power supply, you risk overheating your charger, burning it and in many case your device will stop functioning and/or charging.

Is a 1.5 volt battery the same as a AA battery?

A 1.5-volt battery is the same size as AA batteries, but is rated for lower voltage to suit a device with a lighter power requirement such as a flashlight. Just be sure not to mix the two up—because they’re exactly the same battery. Mixing them together will result in low-voltage operation of electronic devices.
