I have been buying Deka batteries from Tech Solutions. Quick shipping. Batteries are always fresh.
I replace mine every 4 years whether it needs it or not. I use the old battery in my lawn tractor.

I had the big crank, worked well always on a tender, lasted 3 years. This time I went online to Advanced Auto Parts and bought their's. They always have online coupons which is a nice discount and walk in and get the freshest one off the shelf.

 

 

Deka batteries purchased on eBay. Takes 2-3 days for them to arrive. Good battery at a good price.

 

Check the Lowes web site, you'll have to order it and prepay then pick it up. Advanced Auto Parts, Autocraft , I believe are Deka/East Penn.

 

YUASA. Don't try and save money. Get 500CCA if having trouble with hot starts.

 

Here's a 600 CCA battery getting great reviews.

 

Advance Auto Parts has a sale going on now on their AGM batteries, 20% off online code...
My Duracell is still running strong approaching 5 years.
I like a 2 year warranty and local walk in for battery issues. Mine came from Batteries Plus, they said I am "In The System" nationwide, no receipt necessary at any of their stores.
Reminds me of a car battery that went flat out dead while in South Florida. Glad it was a Walmart Battery, and a Walmart was only about 3 blocks away at the time. Some other type of battery I would have had to buy a new battery, and play around with the warranty I guess when I got home, or trash it all together and just be out the green.

 

all bike batteries are junk. i usually get mine off eBay, around $60 shipped for an AGM. there are only a couple companies making batteries, most are just rebadged from other manufacturers. Deka Johnson controls and exide are the only US manufacturers left.
