There isn't much that else compares to the genuine Trojan's.
They are made better and actually have a lot more power than some of the cheap
knock offs. Prices have been rising quite a bit too. The word I got was that Trojan failed to lock in the lead price
with the smelters and so is buying
on the open market lead prices.
If you were not going with Trojans I would suggest AGM's IF you can readjust your charging
system to handle AGM's. If you can't then you'll trash them sure as anything. They need a different charging
profile. I did that with my previous boat and it was great. My current
boat requires I change out the regulator
and I wasn't ready for that expense so bought Trojans at about 50% more than they used to be.
