Guest 1.5A Maintainer Charger - 2701A

Guest 1.5A Battery Maintainer & Charger (2701A)

The Guest 2701A is a specialized, fully automated 1.5-amp battery maintainer designed to keep your 12V batteries healthy during the off-season or long periods of inactivity. Unlike high-amperage "bulk" chargers, the 2701A is engineered for precision long-term maintenance, ensuring that your battery stays at 100% charge without the risk of overcharging or "boiling" the electrolyte.

Intelligent Maintenance Technology

The 2701A features a sophisticated microprocessor that monitors battery voltage and only applies current when necessary. This "smart" cycling prevents sulfation (the leading cause of battery failure) and ensures that your boat, jet ski, or classic car is ready to start the moment you need it. It is an ideal "set-it-and-forget-it" solution for seasonal storage.

Key Features:

• Fully Automated Operation: Automatically switches between charging and maintenance modes based on the battery's needs.

• 100% Waterproof & Shockproof: Rated for the marine environment, the unit is fully potted (epoxy-filled) to protect against moisture, salt, and heavy vibration.

• Universal Compatibility: Optimized to maintain all 12V Flooded (Lead-Acid) and AGM batteries.

• Compact, Low-Profile Design: Small enough to be permanently mounted in the tightest engine compartments or storage lockers.

• Comprehensive Protection: Features built-in safety mechanisms including Reverse Polarity, Over-Voltage, and Over-Temperature protection.

• Ignition Protected: Safe for installation in engine compartments of gasoline-powered vessels (meets USCG standards).

• LED Status Indicator: A simple LED light provides immediate feedback on the maintenance status.

Why Choose the Guest 2701A?

While larger chargers are great for fast recovery, they are often overkill for simple storage. The 2701A is specifically designed for Battery Maintenance.¹¹ It is the perfect companion for a starting battery on a boat that sits for weeks at a time, or for keeping a generator battery primed and ready for an emergency.

Pro Tip for Storage:

If you are storing your boat for the winter, ensure your battery is clean and the terminals are tight before connecting the 2701A. For the easiest access, you can mount the Guest AC Plug Holder on your console or trailer frame so you don't have to climb into the boat to plug it in.
