Description

CTEK CTPRO120 (40-230) - PRO120 Professional 120AMP 12V & Lithium Battery Charger

Professional-grade 120A battery charger for workshop, fleet, marine, and industrial applications requiring rapid charging and lithium battery compatibility. Delivers exceptional 120 Amp charging current for rapid replenishment of large battery banks (200-1000Ah) where charging time is critical and downtime must be minimized. Features comprehensive battery chemistry compatibility including 12V lead-acid batteries (wet/flooded, maintenance-free, AGM, gel) and lithium batteries (LiFePO4/LFP) with dedicated charging profiles ensuring safe optimal charging. The fully automatic multi-stage charging process adapts to battery type, capacity, and condition through bulk charge, absorption, analysis, and maintenance stages maximizing battery lifespan and performance. Designed for demanding professional environments including automotive workshops, marine facilities, fleet maintenance, caravan dealerships, mining operations, and industrial facilities requiring reliable high-current charging infrastructure. The 120A output dramatically reduces charging time—a 200Ah battery charges in approximately 2-3 hours from 50% rather than 10+ hours with conventional 10-20A chargers, maximizing equipment availability and operational efficiency. Features robust construction withstanding workshop environments, comprehensive safety protections including reverse polarity protection, short circuit proof design, and spark-free operation. Distributed by Bainbridge Technologies, Australia's leading power product experts with over 30 years of experience, backed by comprehensive technical support, installation guidance, and commercial warranty coverage.


Product Overview

Professional 120 Amp battery charger designed for workshop, fleet, marine, and industrial applications. Compatible with 12V lead-acid batteries and lithium batteries (LiFePO4/LFP). Features fully automatic multi-stage charging, robust construction, and comprehensive safety protections for demanding professional environments.

Important Notes:

Professional Installation Required: High-current equipment requiring dedicated 15-20A AC circuit, heavy-gauge DC cables (minimum 25mm²), proper grounding, and secure mounting in ventilated location. Not intended for casual consumer use—designed for qualified technicians in professional settings with proper electrical installation and operator training.

Lithium Battery Compatibility: Verify lithium battery compatibility before use. Battery must have compatible BMS accepting 14.6V charge voltage and permit external charging. Consult lithium battery manufacturer confirming CTEK PRO120 compatibility. For lead-acid batteries, compatibility is universal.

Suitable for Large Batteries Only: Designed for battery banks 200-1000Ah. Smaller batteries (under 200Ah) may be stressed by 120A current—use lower-current chargers instead. Calculate charge time: (Battery Ah × Discharge %) ÷ 120A = Hours.

Ventilation Essential: High-current charging generates significant heat. Install charger with unrestricted airflow, ensure battery area adequately ventilated preventing hydrogen gas accumulation, never charge in sealed compartments without forced ventilation.

Heavy-Gauge Cables Required: Use minimum 25mm² (4 AWG) copper cable, preferably 35mm² for runs over 2 meters. All connections must be professionally crimped or soldered. Install 150A fuse near battery positive connection. Poor connections create fire hazards at 120A current.

Frequently Asked Questions

Q: Can I use this charger on my caravan lithium battery or boat lithium house bank?

A: The PRO120 has lithium (LiFePO4) charging capability, but you must verify compatibility first. Check that your battery accepts 14.6V charge voltage, has a BMS that permits external charging, and accepts 120A charge current (check manufacturer's "C" rating). Always consult your lithium battery manufacturer before charging. For lead-acid batteries (AGM, flooded, gel), the charger is universally compatible.

Q: How long does it take to charge a battery with 120A and what size batteries can I charge?

A: Calculate charge time: (Battery Ah × Discharge %) ÷ 120A = Hours. Examples: 200Ah at 50% = ~50 minutes, 400Ah at 50% = ~100 minutes, 600Ah at 75% = ~225 minutes. Suitable for 200-1000Ah batteries. Batteries under 200Ah should use lower-current chargers. The 120A dramatically reduces downtime—a 400Ah bank charges in under 2 hours versus 10+ hours with 40A chargers.

Q: What power supply do I need to run this charger?

A: Requires dedicated 240V AC circuit with 15-20A circuit breaker. Standard Australian 15A power outlet is sufficient if on dedicated circuit (not shared with other equipment). The charger draws approximately 8-10A from mains during peak charging. Have a qualified electrician verify circuit adequacy if uncertain.

Q: Can I leave this connected for maintenance charging or should I disconnect after charging?

A: The PRO120 has automatic maintenance mode making it safe for extended connection. However, in busy workshops, disconnect after charging to free the charger for next service. For long-term storage (boats, caravans off-season), the charger can remain connected maintaining optimal charge. Ensure adequate ventilation for long-term charging, especially with flooded batteries.

Q: Is this suitable for DIY home use or is it really for professionals only?

A: This is professional equipment NOT recommended for typical home use. The 120A output is excessive for consumer batteries (under 200Ah), requires proper electrical installation with heavy-gauge cabling, and demands operator training. Standard CTEK chargers (5-25A) like MXS 5.0 or CT5 Time To Go are appropriate for home use. The PRO120 is only suitable for serious enthusiasts with 400Ah+ battery banks and proper facilities, or professional commercial applications.
