My original battery still seems strong, and the car has served as a mobile 'jump box' for diesel trucks many times. But, I'll do a load test on it to be sure and start scoping out replacements.
I's be inclined to agree with Sia. I had the car going berserk when i came back from work one eve about 6m ago, as detailed by the OP. The plip didn't open the doors and the siren was going, so I logically determined that it was a dead 12V. I volt tested it and it was flat as a pancake, so I shoved in the old battery from my wifes Insight (though had to get a pair of terminal adapters (I2 is very sensitive to constant 12v, more so than the I).
Unfortunately, that original battery, which failed in the south of the UK - a very mild climate by any measure at 4 years of age could not be revived using a battery reconditioner. I can't say if its a budget battery, and I didnt replace the acid, but it's effectively now powering my motorbike tyre inflator - that's about all its good for.
The stock Honda I2 unit was a Yuasa battery, which appears to be better, although it's slightly lighter, but is of the same case size... so if I get 2 years out of it, ill be happy.
The most annoying thing is that giant sized positive terminal, which was a total pain to tighten back up with a terminal-adapted replacement battery.
