The Power-Time PTC-LA6 is a professional quick charger for BB-LA6 lead-acid batteries, engineered to provide controlled and reliable battery charging. Its three-stage charging circuit is managed by a digital processor to deliver the appropriate charging current and voltage throughout the charging cycle.
During the bulk charging stage, the battery is charged at a high rate until it reaches the preset terminal voltage. The charger then gradually reduces the charging current while maintaining the specified terminal voltage. Once the charging current falls to approximately one-tenth of the bulk charging rate, the charger transitions to the next stage to help prevent overcharging and support longer battery service life.
The PTC-LA6 also incorporates automatic capacity detection. When the connected BB-LA6 battery reaches a saturated state, the charger stops the charging process and changes the indicator to green READY status.
An automatic temperature detection function provides additional charging control. When the battery temperature is too low, the charger reduces the charging current to a micro-current level until the battery temperature returns to the normal operating range. The charger then automatically resumes normal-current charging.
With its wide-range AC/DC input, reverse-polarity protection, intelligent charging control, and rugged professional design, the PTC-LA6 provides a practical charging solution for BB-LA6 battery systems used in demanding operational environments.
The Power-Time PTC-LA6 is designed for charging BB-LA6 lead-acid batteries and is suitable for:
