Important Notice This manual contains important safety, operation, and installation instructions. Please read all instructions before using your Powermania Turbo MV2 onboard battery charger. WARNING: CHECK BATTERY TYPE This charger is designed to charge only Lead Acid type 12V DC batteries; Flooded Lead-Acid, AGM (Absorbent Glass Mat), and GEL (Gelled Electrolyte Lead-Acid).
Introduction INTRODUCTION Thank you and congratulations on your new purchase of the Powermania Turbo MV2 series onboard battery charger. This charger is waterproof, corrosion-resistant and shock-resistant— ideal for recharging and maintaining 12V DC batteries in various marine applications and other harsh environments.
Safety Precautions grounded negative terminal from the battery first. • Be sure to have enough open space around the battery for good ventilation during charge. Gas fumes can be vented amd blown away by using a piece of cardboard or other non- metallic material as a fan.
Feature Highlights FEATURE HIGHLIGHT: Adaptive Loading USER Fully charges all connected batteries in BENEFIT: the shortest time. 10 % 50 % 50 % 90 % The Adaptive Loading feature adjusts the charger’s output level dynamically on each output bank. This allows more charging power to automatically go to the more depleted battery and less power goes to the battery that is closer to a full charge.

Feature Highlights FEATURE HIGHLIGHT: 3-Stage Smart Charge USER Maximizes battery potential and pro- BENEFIT: longs battery life. Turbo MV2 charges a battery in three sequential stages: Bulk, Absorption, and Float. This method is proven to bring a battery to its fullest charge, as well as maintain a fully charged bat- tery’s from self discharge.
Installation INSTALLING THE CHARGER The Powermania Turbo MV2 series charger is designed to be mounted onboard a vehicle or watercraft. The chart below shows the proper orientation of the mounting position. The top row LED lights line up horizontally at the top and the output cables at the bottom of the charger.
Select Battery Type SELECT BATTERY TYPE The Battery Selector’s tip point can be switched in three positions: Refer to the illustration below. From left to right, the first position (factory setting) is for charging Flooded Lead-Acid type and AGM type batteries. The middle position is for charging GEL (Gel Cell) type battery, and the right position (AGM+) is for charging high-performance AGM type battery (Odyssey and Optima brands AGM).
TO PREVENT SPARKS. CONNECT THE DC CABLES The following pages demonstrate proper DC wiring configurations for Powermania Turbo MV2 series chargers. When making DC connections, make sure each set of output cables (one positive and one negative) is connected to the same battery set of terminals. The red wires are positive (shown as grey color on the diagrams) and the black ones are negative.

Operating instructions OPERATING THE CHARGER Install the charger and make appropriate DC wiring connections as per the wiring dia- grams. Choose an appropriate setting on the Battery Selector (page 11). Plug in AC power cord to properly grounded outlet. The Power indicator LED will display green, indicating the presence of AC power. The charger will go through a brief test cycle if all the DC outputs are properly connected to a 12V bank.
Troubleshooting ALWAYS DISCONNECT AC POWER CORD PRIOR DANGER: TO MAKING ANY DC WIRING CONNECTION CHANGE OR WHEN CHECKING FUSES. TROUBLESHOOTING Problem Possible Cause Solution Check AC input connection. Make sure AC No AC input. power is present. Power indicator is Check and correct battery wiring connection not on.
Other Information FUSE REPLACEMENT INSTRUCTION • Make sure the charger’s AC power cord is unpluged, and all the DC outputs are discon- nected from batteries. • For cylinder style fuse holders used in 12 Amp and 20 Amp models, use a towel or clothe to enhance grip to pull open the fuse holder.
