This battery clearly had impact damage of some kind and appears to have been dropped on it's corner with enough force, that the lid cracked open. We advertise our batteries as being up to 15 times more resistant to vibration than standard flooded batteries and they are very robust, but they do have their limits. The original owner didn't mention anything about this damage, so we don't know how or when it occurred, but we do know dropping any battery with enough force to crack the battery case itself will lead to failure.
Likewise, the original owner didn't mention anything about the condition of the top posts on the other battery, which also show signs of significant and repeated impact damage. The force with which one of the terminals was hit was strong enough to distort the post and quite probably damage the battery internally and prevent it from functioning properly.
While this damage could've also occurred from dropping the battery on the top post, it is also commonly found on batteries that were installed under a hood that did not have proper clearance or on batteries where a hammer was used to install a damaged clamp. Whatever the cause, the effect of a bent post on any battery is shortened life.
We use a clay ball in all of our fitment studies, to make sure there is plenty of clearance between the top of our battery terminals and anything on the hood that may come in contact with the battery. We also encourage all customers who are installing our batteries in what we consider "custom fitments" to also carefully check their clearance with a ball of clay. Anyone who has ever dropped a wrench across a battery's terminals can tell you how dangerous that can be and a close encounter with a hood can have a similarly disasterous result. For that reason, it is also a good idea to make sure unused terminals are properly-covered, to prevent accidental contact with metal objects.
All three batteries were deeply-discharged below 6 volts (10.5 volts or less is generally considered 0% state of charge), but because of the obvious physical damage to the first two batteries, Optima Jim wouldn't even think of attempting to recharge them. The third battery is currently being charged and even though it started out below 3 volts, it is currently over 12 volts and hopefully will be able to hold a full charge when charging is complete. This isn't necessarily a quick process though, so we understand that some folks may lose interest after a few hours and cast aside a perfectly good, but deeply-discharged battery.
