Noco Genius 10 Battery Charger review. Unboxing and review of the Noco Genius 10 Battery Charger & Maintainer Tested on a 38-month old Optima Red Top Group 25 AGM battery.
Is it normal in 12V AGM charging mode that when the green light has already flashed once, i.e. the full charge is about to end, the voltage drops again and the device flashes orange, i.e. is back at 75%? Or is this due to the charging curve, which registers that the battery is still weak and needs more charge to maintain the final voltage?
I have an AGM battery that is 12 years old and has just begun to give me problems. Do you think it's worth getting one of these to try to repair it, or is the battery just too old?
Wow! A 12-year-old lead acid AGM battery is ancient. If you only have enough money for a battery, I would buy the battery. If you can afford both a battery and a Noco charger, that is great. Then you can ensure the new battery is properly maintained and you should get a long life from it. You may or may not have luck trying to recover a 12-year old battery. I would not plan on going on a long trip with a 12-year-old battery. Just my 2 cents.
When charging the battery, it will stay as a solid green light after fully charged and remain that way. If left for days or weeks at a time, it will continue to charge when needed.
These days it seems to be hit or miss when buying an Optima battery. The original inventor and manufacturer made excellent batteries. There were also popular with the US Military. Then, the company was sold to Johnson Controls and they moved the factory to Mexico and all Optima batteries made since 2007 are made in Mexico. The quality seems to vary these days. I like the fact that they are spill-proof batteries that won't make a rusty mess of the engine compartment from leaking acid. That is about the only think I like about Optima these days. If you discharged your battery too low, many battery chargers won't work. The Noco will still recognize the battery and try to save it, if it can be saved.
@@JohnsGarage It is frustrating that a cheap Walmart battery is better and more recoverable than an expensive Optima battery. The good old ones look exactly the same as the junk new ones. It is painful trying to salvage a discharged expensive battery that won't recharge no matter what you try.
It should. It has less to do with the make or model of the vehicle and everything to do with the type of battery. This will work with all traditional 12 volt flooded (lead-acid and water) batteries used for Starter, Lights, and Ignition (SLI), 12 volt maintenace free batteries, and all 12 volt Absorbed Glass Mat (AGM) batteries. It works on marine, and deep-cycle batteries. Also, works with traditional 6 volt batteries (like they used to put in cars 60+ years ago). I won't get into vehicles that have start/stop engine technology batteries, or hybrid batteries.

Do you need to take the battery cables off before you charged it?
I charged the battery while it was still connected in the car.

@JohnsGarage I bought the charger, and it worked. I'm still running on the old battery.
After left connected for a couple of hours, does the solid green go back to standby mode?

I have had problems with Optima batteries. Even if only discharged for a few days, they will not accept a charge, no matter what tricks I try.

Would this charger be compatible with a 2013 F150 3.5 EcoBoost truck?
