Hopefully, this message will go to SecretSquirrel - well...the saga of my J15 just got a lot more interesting. The other day, I received an "Inverter Overload" message. I immediately shut the unit down, disconnected all devices, as well as AC power. I removed the battery pack and inspected the fuse. While it didn't look blown, I didn't take any chances. I ordered replacement fuses from Amazon...and installed a new one. What I should have inspected were the batteries, as the cases of both were split open. While I don't mind replacing the batteries, I'd like to know if it's going to be a waste of time and money, at this point? Also, there's a big styrofoam spacer which occupies the remainder of the battery compartment. Could this be causing a heat issue?
I recently experience the same as your and I'm still confused what really happened. I hope someone could shed some light on this.
Were you able to find the date code on the batteries?
RE: ( big styrofoam spacer ) wonder if that just for shipping reasons?
This post is a few months old. As such, I did not get the battery date codes. I went to Batteries and Bulbs and had two new batteries installed, as well as another new fuse. They re-installed the styrofoam spacer, as well. When I wrote the manual for the J15, I was unaware they were putting these spacers in the battery compartment, thus I don't know if they are supposed to be removed, or not. The battery compartment can hold up to 4 batteries, and I believe, was designed to do so - as such it would double the runtime. The unit is powered on 24/7. and as such, is always at a full charge. I haven't had any problems with it since the new batteries and fuse were installed.
