Question: can the G1110 be used to charge 12V car batteries, also can we connect it and leave it as a charge maintainer on the battery on vacation.
Document: It is a smart charger so you can leave it connected with no worries about over charging the battery.If you are looking for a good battery maintainer, this is perfect. I also have a classic car that does not get driven very often. When I started, the charger showed it was about half charged. This brought it to a fell charge in about 24 hours.I was a little skeptical because it is so small and made of plastic. I guess that is the marvel of modern electronics.
This G1100 battery charger is rated at a relatively low charge current of 1.1 Ampere (Amp). It charges 6V and 12V lead-acid batteries sized from 2.2 to 40 Ampere-hour (Ah). The smallest automobile battery I ever owned was around 400 Ah. Needless to say, the G1100 will NOT charge a fully discharged automobile battery. It is made for charging small motorcycle or lawn tractor batteries. However, it can be used as a maintainer of large automobile batteries in good shape.
This battery charger is great for people who have low levels of technical skills. I don't know much about car batteries and I needed to leave for a month for a business trip. So I used the G1100 to charge and maintain my car battery. When I came back from my trip, the charger showed 100% charge and the battery was ok and ready for use. I highly recommend this product.
I ordered 2 units on two occasions and both failed. I'm feeling a bit defensive, but I treat equipment with reasonable care and think I know the limitations what with a BSEE degree. Maybe the BS is a handicap  ...The unit didn't strike me as particularly robust being uncased in plastic. The selection of 6V and 12V was attractive since I had multiple batteries. I used them to charge a guitar amp (Pignose) and car batteries. The battery health of both applications was prolonged significantly.
I've had this battery charger/maintainer for a little over two weeks and found it ideal for putting a charge on our riding mower which doesn't get used for several weeks between mowings. If not for the charger, we'd have to drive our pickup down into the meadow to the tool shed to put a jump start on the battery. Now, with the NOCO Genius 6V/12V Smart Battery Charger and Maintainer we can keep enough charge to get it started between mowings.
Ordered this item for a 12V battery used for survey equipment. It's nice to know I can leave the battery charging with this device. Very nice packaging and brand new parts.
It also performs a self test upon power up.My application is to charge and maintain my grand daughter's "PowerWheels" KFX four-wheeler. I can now leave one of her 9.5 AH batteries on charge indefinitely - and know it is being perfectly maintained - while not being overcharged.Since I upgraded the KFX motor voltage from 12 to 18 VDC, (added a 6 VDC battery)- it still charges/maintains both equally well.
I like the G1100 because it charges both 6V. & 12V. batteries.The L.E.D. 's let you know how far along the charging process is.It brought a low garden tractor battery, up to full charge in about 2 hours,and my pickup battery, that was at 25%, up to full in a day.This is only a &#34;trickle&#34; charger-maintainer.
I used the G1100 smart battery charger last winter on my car battery that I left at my lake house in Michigan. When my car battery died from cold weather the G1100 was amazing. It restored my battery which I thought was a lost cause. Now, I also use it on my jet ski in the summer. It's great that you can us it on multiple batteries. All I need to buy is one and that is why I love the G1100 battery charger.
Would highly recommend this, works flawlessly and 100% reliable at 12V or 6V. No boiling off, no freezing  a TRUE battery float. I have used many from very cheap and extremely expensive many companies specification are much to be desired. The bottom line to anyone is will my battery be fully changed in volts and the most important amps and this little gem does this, also it is very well built and made to last.
