Battery post & terminal shut off switch



Hi, one of the battery posts on our battery is a bit bent out of place (as you can see in the photo), is this anything to be concerned about?

Also, bought a terminal shut off switch to be able to turn off the battery so we don't drain it from phantom power on the bus, however it is too large for the battery post, any suggestions for this??

Thanks!

Obviously the picture of the battery post is not showing up however.. (yes, newbie here, tried uploading it from imgur but that didn't seem to work)

Aha, here it is. (was using the share link instead of the direct link)



Dunno if this should be something to be concerned about?

I am not someone knowledgeable, and I would not trust my opinion. However, since noone else has posted here, I will share my untrustable opinion with you.

If I were in your position here's what I would do.
1. I would check the voltage (with an multimeter) ideally against another battery in a similar state. Assuming it is providing a reasonable voltage (between 11.5-14) that will show that it is able to provide an electrical charge.

2. I would clean the surface this battery and charge it with a tricklecharger. I would possibly pour a light coating of baking soda around the battery terminal beforehand. I would charge the battery "fully" with a trickle charger and monitor the status of the battery as it charges (to see if it leaks any acid). Assuming it does not, I would "equalize" (I could be wrong about this) by unplugging the charger and recharging it. I would do this a few times. If no battery acid spills then I would presume it is okay and I would make sure this is in a somewhat ventilated area (aka not where I will be breathing air).

Once again, don't trust my opinion but perhaps it will give you an idea.

Also here's a picture of a battery.

My guess would be that if it produces consistent voltage it will probably just have a crooked block thing inside, which would make me assume that the upper section is corroded, which would make me assume that it will go bad sooner than later.

In case I didn't make it clear enough, I have very little education in electronics and should not be trusted without a big grain of salt.

Alright, thank you! It is a very new battery, but the compartment it's in makes it hard to pull out with ease and it may have gotten bent out of place from that.

I agree with Taolik, but, don't just charge it in a ventilated space, do it outside in case of catastrophic failure. Batteries have exploded in some situations of a leak and a spark.

I would recommend either getting a lower profile battery, or engineering a way to make that compartment an inch taller.

And wear gloves and safety glasses when handling it. getting blinded by an exploding battery would ruin your day pretty quickly.

One last thing, don't try to bend it back if it isn't leaking, that could actually make it start to.

Good luck!

Never lift a battery by the cables. That one has a nice handle too.

If you can tip the battery on it's side and no acid comes out it may be ok, after you follow the other recommendations. In a hardup situation I'd put a little silicone caulk under that terminal.

If there is any chance that liquid can get into the battery around that post, DO NOT clean with baking soda, or any type of battery cleaner for that matter. If it gets into a cell it will kill it.
