NOCO Genius 12v 24v 20 Amp On-Board 2 Bank Marine Charger GEN2
Product Description

The NOCO Genius GEN2 charger is an 8 step, fully automatic, 2 bank switch-mode battery charger which automatically determines the condition of your batteries before beginning its charge cycle. It will only charge when the batteries need it, and will fully maintain your battery when it is in storage or between uses. All of the Genius line of battery chargers are programmed for optimal battery charging and maintenance, with proprietary Rapid Charging Technology (RCT). The smart microprocessor and advanced high frequency design will charge batteries twice as fast as a conventional transformer-based marine charger, while always preventing overcharge. This assures you of maximum battery life and less downtime. Genius chargers also utilitize Variable Input Compensation, which means that your charger will work as it should, delivering its full, correct voltage and amperage, whether or not long extension cords or low AC power are used.

Pros: Can be bought at huge discount.

Cons: Doesn't recharge as needed. Charge LED indicator is so bright, that you can't install unit in a sleeping area. No good for boats left at marina. Return shipping is still full price.

Other Thoughts: The unit goes through a charge cycle and then effectively shuts off for 24 hours. If you use battery power during that 24 hours, it just let's the batteries stay discharged. If you have a 12 volt refrigerator, a bilge pump or anything uses battery power, you could arrive at the marina ready to go out, only to find your batteries dead or deeply discharged. The charged LED will still glow brightly though. If you want a manual charger, you can get one much cheaper at walmart. **NOTE from** The GEN 2 is working correctly, but is not designed to act as a power supply to combat constant battery drain.

Pros: works as advertised

Cons: When I bought my charger I was told it had a 3 yr warranty. It's really a 1 yr with 2yrs prorated. As if it were designed to do so, mine gave out after a year. Noco said send $66 and they'll send a new one. I've now spent $266 on a charger. I could have bought another brand from Basspro for $100.

Other Thoughts: If it's going to go out anyway why buy the "GOOD ONE", just get the cheaper one and replace as needed.
