Acid leaking from battery

I had a bad battery. Battery was dead could not start car when I opened Hood there was lots of powdery acid corrosion around the terminal. I jumped the car and went and got a new battery two weeks later there's a bunch of powdery acid on this new
battery could the battery be bad or does this mean that my alternator is overcharging? Any help would be much appreciated thank you

Just because it tested OK has nothing to do with this concern.

Each battery post is (supposed to be) sealed were it exits the case......otherwise, acid and hydrogen gas wick up the post and destroy the cables (and anything else it gets on).

If the battery is actually being overcharged it will outgas from those 2 little vent ports sticking out the side of the case (unless the installer forgot to pull the shipping plugs).

I am saying the battery case seals at the terminal exit points are not sealing as designed. A construction defect.

It sounds like you had a post seal failure in conjunction with a internal battery (electrical) with your previous battery.

Post seal failures are uncommon but I see several a year........you are the lucky one that got two in a row.

The battery is leaking at the posts.....return it for one that doesn't.

Edit and addition: Last year I replaced the battery on one of my motorcycles......never had terminal corrosion till this replacement.
Yep, leaking at the positive post......vendor replaced it without whining.

Just a fyi.
