NOCO Genius G750 and G1100 Charger and Maintainer

I have looked into NOCO chargers in the past but never purchased one until recently.  I recently saw some good prices ( Amazon lightning deals ) and ended up buying two units - the G750 and the G1100.

Here is a quick rundown of the features/specs (not a full list of course):

- Both units can charge 6V and 12V lead acid batteries and use a multiple step charging approach
- The G1100 can also support 12V Lithium-ion batteries
- The G750 is IP60 rated and the G1100 is IP65 rated.  So they have the same solid protection (1st digit, 6 which is basically dust tight) but different liquid protection (2nd digit).  The G750 (rating of 0) has no protection, and the G1100 (rating of 5) protects against "powerful water jets" so basically rain shouldn't be an issue but don't put it under water.
- Both units come with clamp connectors w/ integrated eyelets, and they have a range of adapter/cables that you can purchase.
- Both units come with a 5-year warranty which is impressive.  Assuming you keep the receipt and register the unit, 0-2.5 years is no charge and 2.5-5 years is 35% of MSRP.

If you aren't familiar with the NOCO units, read up on them they have some neat features ( battery recovery, diagnostics etc ).  Product info links: G750 and G1100

Once I got the units, I tried them on a 6V battery that I had from one of those kid ride on cars.  The G750 wouldn't even get started, so I put the original charger on it for a while.  I put the G750 on it again, and after a while it would given me an error light.  I figured maybe the G750 didn't have enough power to bring the dead battery back so I tried the G1100 and it also gave me an error indication.  Ultimately, the battery itself was just beyond repair - it had been sitting in the garage for a while and I didn't keep it charged (I should have gotten a NOCO unit a long time ago).

Trying to charge the 6V battery

I also tested the G1100 against a few car batteries.  Since these were cars that were used often/recently none of the batteries were dead or near dead, but as far as I could tell the charger was working.

Topping off a Optima car battery

Once I purchased a replacement 6V battery, I used the G750 to fully charge it.  One of the nice features about these units is that they work as battery maintainers.  You don't have to disconnect the charger just leave it plugged up - it will monitor the battery and top it off as needed.  For situations where you don't use the battery often, this is a great capability.

Charging the new 6V battery

Ultimately, I think the G750 is perfect for indoor / garage use to keep things like the kid ride on toys or other batteries charged and maintained.  However, if you plan to use it for cars that are outside of the garage I would recommend the G1100 due to the better IP65 rating.  Ultimately, I think the NOCO Genius chargers are very nice options and you just need to select the best one for your use.  Don't make my mistake and let a battery go bad before you decide to get a NOCO charger!
