Ionic Emergency Starter Installation Question
Hi everyone. Going through some old threads about the 12v battery drain issues and noticed this Ionic Emergency Starter that a number of members have posted about.
Here is a link to one of the more expensive sites (available on a number of other sites for about $30 less) but it has the installation manual in the ‘documents’ link so I thought that might be helpful for some people.

I was specifically wondering where and how this would be installed on a 450h+.
Would anyone mind sharing their experience and even some pics or video if you wouldn’t mind?
I am not a ‘car guy’ so messing with the battery and electronics have me wanting to make sure I understand 100% before buying and attempting the install.
Thanks so much in advance!!

I used a small socket to temporarily remove each post nut, looped the respective (+/-) cable on and screwed the bolts back on. 5 minute job. Be sure to charge the unit first tho using a trickle charger (simply clamp the alligator clip to the flat round wire end). Hope this helps!

Yes and yes. No electrical worries. Note: I will remove this before my 5K service to avoid any warranty issue with Lexus. But I'm also getting them to perform a deep battery check as it pretty quickly falls into a "Low Charge" range. I want my concern documented for any future replacement.

Thank you! So you installed on the battery itself under the trunk floor then? Did you use Velcro to attach? How is the fit?
