I have a Battery Tender battery charger.

Only used it in the garage while battery was in the 850.

Is it safe to remove the battery and charge inside my apt? Something tells me “NO”.

I’ll be home while it’s charging.

I don’t live in the same place, and no access to an outlet outdoors.

Thanks!

Thanks I was able to find a new one, fresh from Sweden. Oddly enough I know the tank isn't cracked on the bottom as the tank can hold some liquid. However if you fill it up, it leaks immediately. So a replacement is needed.
