battery not holding charge and only 4 months old!!!

I have also had issues with my batteries too. And they weren't that old. I tried multiple things trickle charge regular charge with no success. I think I'm going to switch brands to Odyssey.

Which is recommended for a small RV trailer the 8006-006 or 8016-103?

I no longer recommend Optima batteries. The manufacturer cheapened the components and raised the price. They now last no longer than other, less expensive batteries. In 2008 they would last 12 to 14 years. By 2014, they lasted about 2 years and cost $267. But my 2008 Optimas in my boat still work perfectly.

Is this a SC34M? All I see is "34M" IS it the same?

Why would buying the battery from Amazon have anything to do with its quality? Amazon gets the product from many of Optima’s Authorized dealers so… saying “Don’t buy it from Amazon is a ridicules resonance.

Will this battery start a backhoe? Has a 4 cylinder Perkins Diesel

if its 12 volt it might start it in the summer
