Everstart BC50BE Battery Charger

What are the main features and functions of the EverStart BC50BE battery charger?

The EverStart BC50BE is a 50-amp smart battery charger with five main functions: battery charging, engine start assistance (40-second high-amperage boost), alternator check to assess your vehicle's electrical system, battery reconditioning (24-hour cycle to reduce corrosion), and reverse polarity protection with an audible alarm. The charger features an LCD screen that displays status indicators and progress for each function.

How do I properly connect the battery charger clamps to my vehicle?

For negative-grounded vehicles, connect the red (positive) clamp to the positive battery terminal and the black (negative) clamp to a metal part of the vehicle's frame or engine block away from the battery. For positive-grounded vehicles, reverse this: connect the black clamp to the negative terminal and the red clamp to the metal frame. Always ensure the charger is unplugged before connecting or disconnecting clamps.

What does the reverse polarity alarm mean and what should I do?

The reverse polarity alarm activates with a continuous beep and displays a reverse polarity indicator on the LCD screen when the battery clamps are connected incorrectly. If this occurs, simply disconnect the clamps and reconnect them with the correct polarity according to your vehicle's grounding system (positive or negative ground).

How long does it take to charge a battery with this charger?

Charging time depends on the battery's condition and current charge level. A fully discharged battery may take up to 8 hours to fully charge. Once the battery reaches full charge, the charger automatically switches to maintenance mode and displays 'Maintaining' on the LCD screen.

What do the error codes E1, E2, E3, and E4 mean?

E1 indicates overcharge protection has been activated, E2 means overvoltage has been detected, E3 indicates undervoltage has been detected, and E4 signals that reverse polarity has been detected. If you encounter any of these error codes, refer to the troubleshooting section or contact EverStart customer service at 1-877-2391.

Can I use this charger on motorcycle and lawn mower batteries?

Yes, the EverStart BC50BE is compatible with all 12V batteries, including those in motorcycles and lawn mowers. However, it is not intended for use with lithium-ion or LiFePO4 batteries—only lead-acid batteries including standard, gel cell, and AGM types.
