Longer Battery Life

Step 1: Make maintenance easy

All marine batteries require regular maintenance, even AGM and lithium-based models.

Put maintenance on your calendar so it’s automatic. Consider storing safety and maintenance equipment near your charging station to save time.

Always wear personal protective equipment, including safety glasses and gloves. Remove jewelry, watches, and other metallic objects or electronics.

Next, visually inspect and clean batteries. Battery covers, ports, and terminals should be clean, dry, and corrosion-free. If you see corrosion (it looks greenish), clean using a wire brush and biodegradable cleaner/neutralizer. Ports, terminals, and cables should be tightly connected and intact with no exposed or frayed wires.

For flooded lead-acid batteries:

– Measure specific gravity (concentration of acid) as advised in your manual.

– Equalize according to your battery manufacturer’s recommendations. (Never equalize sealed batteries such as AGM; it’s unsafe, unnecessary, and damaging.)

– Check fluid levels regularly. After charging, top off with deionized or distilled water to just above the plates — about 2 cm. (3/4 in.) from the top of the cell.

Since batteries are temperature-sensitive, avoid storing in extreme heat and cold. Charge batteries fully and disconnect the negative cable before storing. Avoid storing flooded lead-acid batteries below freezing, and top off with distilled water before and after storing. Check your manufacturer’s storage recommendations.

When you select the right batteries — and properly care for them — you’ll enjoy more time on the water and more money in your wallet. That’s something we can all appreciate.

Neptunus 650F Review

Neptunus 650F 400

By Andy Adams

Over the years Canadian Yachting has had the pleasure of doing several boat review articles on new Neptunus models and we are familiar with the qualities that Neptunus is famous for. They have all been exceptional yachts, but this is the one I would most want to own myself. It’s a personal choice and a matter of taste as to whether you would prefer to have a sedan express model or a flybridge but in my opinion, the flybridge layout offers some wonderful attributes.

We met with Neptunus Managing Director Jan Willem De Jong this past fall to take the new Neptunus 650F out in Lake Ontario.

The Other Virgin Islands

Sunset off St John

By Mark Stevens

I was first seduced by the United States Virgin Islands during a ferry ride from St. Thomas to Tortola to begin one of our earliest British Virgin Islands charters nearly twenty years ago.

A perfect sunset off St. John with St. Thomas views for backdrop.

Clearing Pillsbury Sound, surrounded by voluptuous emerald mountains as the ferry sliced through royal blue waters, I was struck by the unspoiled ambiance of St. John, the island gliding past our starboard beam and the irresistible charm of a village called Cruz Bay visible from our quarter stern.
