My Mastiff nibbled on the top edge of one of my boat batteries in my garage that was on a BatteryMinder. There are teeth marks in the case. I do not think they are through but a little hard to tell. What glue can repair the case if it's through.

I wpuld try some 2 part epoxy or maybe some of the special JB weld type of product.
POLYPROPYLENE is virtually impossible to seal with any glue. Usually one needs to melt it together. Ed
I'd wipe teeth marks with rubbing alcohol or denatured alcohol, then Use some folded 100 grit new sandpaper to scratch inside teeth marks, and then cover the teeth marks with something like 'Amazing goop'
Once clean I would try some 2 part epoxy; I have used this with pretty good success: http://www.homedepot.com/p/RectorSeal-EP..._-100124697-_-N

If the battery is old, I might spent the $8 toward a new one.

I agree with Ed, glue on poly only goes so far. Plastic weld for a long term fix. Cracked a couple boat batteries myself.
This one I bought last summer but never got the boat in the water, so its never been used. Been on a BatteryMinder most of the time.
Tip it over a smidgen to see if it leaks a bit? If it doesn't leak, leave it as is and dont mess with it?
+1
if it does maybe a plastic welder gun used for bodywork?
forget all glues.NONE will stick to polyproplene.
i got a brand new mk agm d31 that was on the scrap pallet with a small hole in the top.got it for a bad one even swap.
i used high temp red hot glue.its still holding after 7 years.high temp hot glue=molten plastic.

3M 4693 or 8005 are your best choices. Most box store stuff will specifically say that the use on pp and pe is dubious...
The jb plastic bonder claims to adhere to polypropylene, but i have not used it. I agree its tough for anything to bond. If its not leaking, i'd just redneck it with some duct tape.
