CTEK’S UNIQUE EIGHT-STEP CHARGING PROCESS:
- Desulfation – This phase detects sulfated batteries. It removes sulfate from the lead plates of the cell using current and voltage pulses, which improves battery capacity.
- Soft Start – Tests the battery’s charge capacity. This step prevents continued charging of a faulty battery.
- Basic charge – The stage charges the battery at maximum current until approximately 80% of the battery's charge capacity is reached.
- Absorption - ready-to-use battery – The battery is charged at a decreasing current until 100% of the battery's charge capacity is reached.
- Analysis – This step tests whether the battery can hold a charge. If the battery cannot hold a charge, it may need to be replaced.
- Regeneration – You can add a regeneration phase to the charging process by selecting the RECOND program. During this process, the voltage increases, causing controlled gassing in the battery. Gassing mixes the battery acid and restores the battery’s performance.
- Maintenance ( battery fully charged) – Maintains the battery voltage at the maximum level by charging it at a constant voltage.
- Pulse, Trickle Charge – This stage maintains the battery’s power at 95–100%. The charger monitors the battery voltage and provides a pulse if necessary to keep the battery fully charged.
- Power: 12V
- Charging current: 7A (maximum current)
- Charger type: 8-stage, fully automatic cycle
- Warranty: 5 years

The D250SE is a fully automatic, 5-stage charger that delivers up to 20A to all 12V lead or lithium batteries* from 40-300Ah. It has selectable charging programs for AGM and lithium* batteries.

12V versatile and fully automatic power management system for dual battery systems. The Smartpass 120S is a 120 amp power management system that distributes, regulates and maximizes the amount of energy available from the alternator to the service battery and loads. The SMARTPASS 120S handles all 12V batteries with capacities from 28 to 800 Ah. The Smartpass 120S charger’s battery guard ensures that critical equipment such as radio, emergency lights and navigation systems always receive power and take priority when the service battery voltage drops, resulting in less critical loads being disconnected. The device’s battery guard protects the service battery from being completely discharged and the built-in temperature protection function reduces the charging current before the battery temperature gets too high. The SMARTPASS 120S is compatible with the 20A D250SA and D250SE chargers.
