Inteli-Power Marine Battery Charger, 40 amp | Progressive Dynamics 2140V

Keep your boat or RV battery bank reliably charged with the Progressive Dynamics Inteli-Power Marine Battery Charger (Part #PD2140V) — a 12V, 40-amp, 3-bank smart charger built specifically for marine and continuous-duty applications. With patented 4-stage microprocessor charging, field-programmable battery chemistry profiles, Marine UL listing, and serious protection circuits, the 2140V is engineered for real-world use where battery health really matters.

Intelligent 4-Stage Smart Charging

The Inteli-Power uses a patented microprocessor that constantly monitors battery voltage and automatically selects the right charging mode:

• BOOST — high-output charging for depleted batteries
• NORMAL — sustained charging as the battery approaches full
• STORAGE — maintenance charging that keeps batteries topped without overcharging
• EQUALIZE — periodic equalization to maximize battery life and capacity

That intelligent mode-switching is dramatically better for long-term battery health than older single-stage chargers. The unit is also designed to charge and monitor batteries while in use OR in storage — so you can leave it connected long-term without worry.

3-Bank Output

The PD2140V features 3 outputs — letting you charge three separate battery banks from a single charger. Perfect for boat setups with separate engine, house, and trolling motor banks, or RV setups with house batteries, chassis batteries, and accessory banks.

Marine UL Listed & Ignition Protected

The PD2140V carries a Marine UL Listing (85JL) and is ignition protected — designed for safe installation in marine environments where ignition-protected equipment is required. That's a meaningful certification: not all 12V chargers are safe to use in boats, and Marine UL listing tells you this one is.

Programmable for Flooded, AGM, or Gel-Cell

Using the charge mode button on the face of the unit, the PD2140V is easily programmed for different battery chemistries:

• Flooded lead-acid
• AGM
• Gel-cell

Each chemistry requires a different voltage curve — using the right profile dramatically extends battery life.

Series or Parallel for Custom Power Systems

The 2100 series chargers can be configured for advanced installations:

Need More Charging Power?

If 40 amps isn't enough for your battery bank, the Progressive Dynamics PD2180V (80-amp, 12V, 3-bank) is the larger sibling in the same Inteli-Power Marine series — twice the charging output for larger battery banks, with the same smart-charging features.

• Parallel — connect multiple units for additional current capacity on 12V systems
• Series — combine units for 24V charging

Built for Continuous Usage

The PD2140V is designed for continuous use, with automatic thermal protection that adjusts output to safe levels if the unit temperature exceeds pre-set limits. That's important for installations where the charger may run for extended periods — you don't have to worry about cooking the unit if a fan fails or compartment ventilation is marginal.

Comprehensive Protection

Multiple layers of protection safeguard both the charger and your batteries:

• Reverse battery protection
• Over- and under-voltage protection
• Electronic current limiting — caps output at maximum rating
• Automatic thermal protection with variable output reduction
• Variable-speed intelligent cooling fan — only runs as fast as needed
