I have a mix of Batteries here. Some are Wal-Mart (I think 2) others are well the big ones are DEKA (made 100% in the USA by the way)
The only "Bad" thing I can say about Wal*mart batteries is not so much about the batteries as it is Wal*Mart
If you look at the amp-hour capacity Wal*mart indicates they test "At the 1 amp rate" The standard rading we use here in the forum is the "20 hour rate)
For Group 24 batteries that is 3.75 amps not 1 amp
So what is the difference.
20 hour rate 75 amp hours
1 amp rate over 100
It makes their batteries look "Bigger" than they really are.
Finally I have looked for Trolling batteries at WM and not found 'em. MARINE/Deep cycle I find. And I see Trolling advertised, but no joy finding them.
