We had to purchase a new trickle charger. I have the Casita battery on one, and my riding lawn mower on another. They both have connectors...you have to screw them onto the posts on the battery. Each charger has a pigtail that has the connectors one one end and a typical two prong 'automotive' connector on the battery end.
The new trickle charger (from O'Reillys) came with both the pigtail and old fashioned alligator clamps. The pigtails have fuses (oddly, one had a 7.5 fuse and the new one has a 10).
The cord ending in the alligator clamps, however, don't have a fuse.
Why would one style (alligator clamp) lack a fuse, and the pigtail (connector) have one?
