Check your panel batteries after that last storm

I was in Nashville last week doing a service call for a system that kept showing low battery trouble. Pop the panel open and the battery is swollen and leaking acid all over the circuit board. Customer said they had a power flicker during a storm 3 days ago and the system never recovered. That battery was only 2 years old. I looked closer and the terminals were corroded because the battery vent was clogged with dust. This is the third time this month I have seen batteries fail after voltage spikes. If you are not checking those terminals and vents during routine maintenance you are going to end up chasing ghost troubles. Has anyone else noticed more battery failures after recent weather?

Three times this month with swollen batteries? That's insane.

Three times in one month is wild. I'd be scared to even leave that thing charging overnight at that point.
