I used to swear by Diehards, then I had 2 fail in a row, so I went to AGMs. Not just one - 4 boats, 2 lawn tractors and a classic car.I replaced all my batteries on my 330DA with AGMs several years ago and have been very happy with them.
I thought they were the end-all, and then they all seemed to fail at once. They wouldn't take a charge, self discharged at a fast rate, etc.
Then I switched to Auto Zone. So far 6 years on a group 24 and its monthly discharge is almost nil.
Its all a matter of cost performance. If an AGM costs double, it has to at least last twice as long.
