CTEK M45 Marine 3.6A Battery Charger

The CTEK M45 Marine 3.6A Battery Charger has a fully automatic, four-step charge: Desulphation with pulsing for sulphated batteries; Bulk is the main charge when 80% of charging takes place, the charger delivering a constant current until the terminal voltage has risen to the set level; Absorption which completes the charge up to virtually 100%. The terminal voltage is maintained at the set level. During this phase, the current drops successively so the terminal voltage does not become too high. If the absorption phase has been in progress for more than 18 hours, the charger switches to maintenance charging to prevent damage if the battery is faulty; Maintenance charging varies between 95% and 100%. The battery receives a pulse when the voltage drops. This keeps the battery in perfect condition when it is not used. The charger can be connected for months at a time but, if possible, check the water level in the battery.

Using the CTEK M45 Marine 3.6A Battery Charger gives your battery an optimum service life and operational reliability.

The CTEK M45 can be very easily set to charge Wet, MF, GEL, Calcium/Calcium and AGM lead-acid batteries. You can use the M45 to charge a range of batteries, from small (1.2Ah) to large (120Ah).

Features

  • Four-step, fully automatic switch-mode model
  • Charges lead-acid batteries (Wet, MF, GEL and AGM) from 1.2Ah to 120Ah
  • Maintenance pulse charging increases battery life and gives superb performance
  • Even charges drained batteries
  • Pulse recovery of slightly sulphated batteries
  • Three unique charging modes for use on small batteries, large batteries and special cold mode that is also suitable for AGM batteries
  • Low back current drain, low ripple and input voltage independent (220-240V)
  • High efficiency: 85%
  • Delivered with two interchangeable connection leads, one with clamps and one with eyelet terminals
  • Charger can be connected for months so ideal for seasonal vehicles
  • Compact design with mounting holes for permanent assembly
  • 5-year warranty

Settings Explanation

  • Mode 14.4V/0.8A: This mode is normally used for batteries less than 14Ah.
  • Mode 14.4V/3.6A: Normal setting for wet batteries, MF and for most GEL batteries.
  • Mode 14.7V/3.6A: This setting is recommended for batteries at temperatures below 5°C. It is also recommended for many AGM batteries. This setting is not recommended for maintenance charging when the temperature at times exceeds +5°C. In this case, the 14.4V/3.6A mode is recommended.

Bulk Charge Time (to c 80%) for Battery Size

  • 2 Ah: 2 hrs
  • 8 Ah: 8 hrs
  • 20 Ah: 5 hrs
  • 60 Ah: 15 hrs
  • 100 Ah: 25 hrs

Safety

  • Electronic-safe, charger will not damage vehicle electronics. Battery does not normally need to be disconnected from vehicle when charging
  • Minimal gas build-up and patent-pending spark-protection system
  • Short circuit and reverse polarity protected
  • Double insulation
  • Splashproof, dustproof (IP65) and approved for outdoor use
  • Progressive temperature protection
  • Tested and approved by Intertec SEMKO
  • AB S-marked and conforms to following standards: EN 60335-1, EN 60335-2-29, EN 55014-1, EN 55014-2, EN 61000-3-2, EN 61000-3-3, EN 60555-2

Temperature

To protect the charger from overheating, the CTEK M45 Marine 3.6A Battery Charger is fitted with power limitation. The power reduces when the ambient temperature increases. The power also reduces if the charger were to be covered, which protects the charger from damage. The charger continues to work but at a lower output. When the ambient temperature drops, the power automatically increases again.

Equipment

The CTEK M45 Marine 3.6A Battery Charger is delivered with two different battery leads, one with clamps and one with eyelet terminals, all colour coded for easy ± identification.

If the battery is difficult to access, the lead with eyelet terminals can be mounted to the battery and the quick connectors are located so that it is easily reached for charging.

You can also purchase additional leads allowing you to have one lead with eyelet terminals fixed to all your vehicles with batteries that are difficult to get at and charge them simply from the same charger.

Specification

  • Model: M45
  • Input voltage AC: 220-240V AC, 50-60Hz
  • Nominal output voltage: 12V
  • Efficiency: 85%
  • Charging voltage: 14.4V/0.8A, 14.4V/3.6A, 14.7V/3.6A
  • Charging current: 3.6A
  • Back current drain*: 1.3mA
  • Ripple**: 50mV RMS, 0.13A
  • Ambient temperature: -20°C to +50°C, output power is reduced automatically at higher temperatures
  • Type of charger: Four-step, fully automatic switch mode with pulse maintenance
  • Type of batteries: 12V lead acid batteries (Wet, MF, AGM, Calcium/Calcium and GEL)
  • Battery capacity: 1.2-120Ah
  • Dimensions (L x W x H): 165 x 61 x 38 mm
  • Insulation: IP65 (splashproof and dustproof), outdoor use
  • Weight: 0.5 kg

*Back current drain is what drains the battery if the charger is connected without the power cord connected. The M45's extremely low back current drain corresponds to 1 Ah per month. Many other chargers have 1 Ah per day.

**Ripple denotes the amount of interference there is to the current and voltage. A high current ripple heats the battery and shortens its life. A linear charger has a current ripple of 70-400% which is much larger than the maximum 5% for a modern sealed battery. Voltage ripple could harm other equipment, which is connected to the battery. The M45's ripple is only 2%. The battery gains a long service life and there is no risk of damage to other electronic devices connected to the battery.
