Did I ruin the battery?

[Sci85]

I recently bout a new AGM battery for the bike. At the same time, I installed the coil relay mod but accidentally switched the batt power and switched power leads and overnight it drained the battery down to 5v. Can these batteries handle that kind of discharge or did I permanently damage it?

Thanks,

It should be fine. Might not have done it any good, but it will still work for a long long time.

Whew, that's good. They are not cheap!

Charge the battery back up, and then see if your charging system still works.

Regardless of battery type, the sooner you can recharge it, the better it will recover.

It may not recover quite to what it was, but since it started better than a "normal" wet-cell battery, you should be just fine.

Yes chances are you probably seriously hurt the life and storage potential -- that is the cardinal rule of AGM batteries Never fully discharge them.

The cardinal rule of AGM batteries:
Never fully discharge them.

Ask me how I know!

Seriously hurting the battery's performance and ruining it are two different things, don't you think?
I bet it still works fine for years.

Yea, I have fully discharged a couple agm's and they lived to charge another day!

Yikes. Its got a warranty. Should I have them test it? I did charge it back up the next night. Seems to be holding a charge. It's at 12.75 after a 10m ride today.
