Battery charger CTEK M 100 12V 7A — 12 V, 7 A charging for lead-acid and AGM batteries

CTEK M 100 is a fully automatic 12 V battery charger with a controlled 7 A charging current, intended for charging and maintaining 12 V lead‑acid and AGM batteries used as starter and service batteries in small boats, cars and similar vehicles. The charger performs an 8‑stage charging cycle, detects battery condition and switches automatically to a safe maintenance mode after charging. It also offers a Recond function to recover deeply discharged batteries and an AGM mode optimised for AGM battery charging.

Advantages

The M 100 eliminates harmful lead sulfate crystals, delivers an effective and controlled charge, and automatically switches to pulse maintenance to maximise battery life. Its Recond mode can reactivate batteries after deep discharge and the dedicated AGM setting ensures appropriate charging for valve‑regulated AGM cells. The unit is fully automatic and suitable for continuous maintenance charging without risk of overcharging.

Key specifications

How to use

Connect the charger to the battery following the manufacturer’s instructions and select the appropriate mode if needed; otherwise the charger will analyse the battery and choose the correct charging programme automatically. Start charging and monitor indicators for charging status. Once the charging cycle is complete the charger switches to maintenance mode to keep the battery at an optimal state. Use the Recond mode only when a battery is deeply discharged and follow safety precautions described by the charger manufacturer.

Recommendations

Use the CTEK M 100 for routine charging and long‑term maintenance of 12 V lead‑acid and AGM batteries. Prefer AGM mode for valve‑regulated AGM batteries and apply Recond mode sparingly to recover batteries after deep discharge. Follow all safety instructions from the charger and battery manufacturers when connecting and operating the device.
