DC electronic ballast

· Battery connection or not: A DC electronic ballast can indeed be connected to a battery, especially the type designed for emergency lighting purposes. Such ballasts are specifically engineered with battery compatibility in mind. These ballasts are typically equipped with a charging device to keep the battery in a charged state and are capable of recharging the battery within a specified time. For safety, they are also fitted with over-discharge protection to prevent the battery from being damaged due to excessive discharge.

· Application scenarios: Emergency lighting systems and other situations requiring DC power supply.

AC Electronic Ballast

· Battery connection or not: Typically, standard AC ballasts are not designed to connect directly to a battery. They are primarily intended to receive mains electricity (e.g., 220V AC) as input and output high-frequency pulse voltage to drive fluorescent lamps or other gas discharge lamps. However, if the battery voltage is sufficiently high (e.g., close to or exceeding the input voltage required by the ballast) and the ballast has proper protection measures to prevent potential issues such as reverse polarity, it is theoretically possible to connect a battery via a conversion circuit, such as an inverter, to transform the DC power into AC before feeding it into the ballast. That said, this is uncommon and requires professional handling.

· Application scenarios: Suitable for homes, offices, and commercial spaces that use mains electricity as the power source

In summary, DC ballasts can be connected to batteries, while AC ballasts are typically not designed for direct connection to batteries. However, it is essential to select and operate the equipment according to its specific technical specifications and safety requirements in practical applications. If connecting a battery to an AC ballast is necessary, it is recommended to consult a professional electrician or relevant field expert to ensure safety and effectiveness.
