I just pulled my WestCo out of my car where it's been sitting unplugged for the last 7 months. I noticed the sides are bowing inwards a bit. I don't know if this is normal or if there is perhaps an issue with the battery? It is still showing 13.2V, and it's currently on my trickle charger. I'm going to load test it on Tuesday at work and see if it's still good. But as for this warping/bowing of the sides, does this look normal?
