Mine ran 6 yrs. I thought tgst was good.

Great battery for the money

Phone system is bad. Couldn't get to battery and tire Dept.

Battery seems to be doing what it supposed to be doing. Very good price.

Bought two in September of 2016, still going strong. They're constantly maintained by 100W of solar and a charge controller, as well as having a dedicated shore power charging. I bought these to get the 215 Ah for running a small fridge overnight while at anchor. I plan on adding two more to give me more time between charges, but never had an issue with solar and alternator charging each day. Even made ice one night at the end of a trip. Ice cubes made from sunshine!!!

I bought 16 GC2 batteries to add an AC coupled battery backup to a grid tied solar array. I am running them in a 24 volt 215Ah configuration, using 4/0 welding cable for the inter connects. This added 20.64kWh of battery backup. About 4 day of power with no sun. With sun, the batteries will feed 240AC back to the array turning it back on in a grid failure. Neighbor has the same battery setup but running off grid solar.

I've had these in my Class A Motor home since 2012 and they still hold 13.1 volts over night with none use of the RV. I have 3, 120 watt solar panels keeping them charged. And I service them regularly about 2 times a year. Plan on getting another set next winter just to avoid and potential trouble when we are dry camping. Batteries seem to last about 8 years before needing to be replaced.

This is a good inexpensive battery. Well worth the price

I bought four of these to replace the existing Interstate GC2 batteries in our motor home. They fit into the battery box, but the placement of the threaded battery terminals is off by just enough that three of my battery cables are not long enough to interconnect the batteries. I am either going to have to find longer cables or return these and go back to Interstate GC2s.

I purchased my current set February 2019. 1 battery failed November 2019. Sams replaced it under warranty. I have been meticulous about checking the water leve, maintaining a charge, and replacing cables, but in less than a year these batteries barely get 8 to 10 miles and not even 8 in colder weather. My previous 5 year old Trojans outperformed these.
