Hey guys,
My trailer has a decent sized marine battery that powers LED lights and a fan on the inside. I want to pickup a charger that will charge it when shore power is available, and also keep it intelligently topped up when parked on my driveway for weeks at a time. The truck's wiring is currently not configured to charge it while moving (truck may be sold soon, so I don't want to mess with rewiring it).
Here's the battery:
What charger do I need for it? I look on Amazon and there seems to be a wide spectrum of chargers in terms of sophistication and cost - anywhere from $50 to $350.
Here's one that seems reasonable - will this do the job?
Amazon.com: NOCO Genius G3500 6V/12V 3.5A UltraSafe Smart Battery Charger: Automotive
For my intended purpose and battery size, do I want the 3.5 amp ($59), 7.2 amp ($93) or 15 amp ($134) model?
Thanks a lot.
