Hi,
Like many on here I have a CTEK battery tender connected to my car when not in use.

I have read the user instructions and it says: to keep the battery in best health press the "Mode button" and select the "Recon" mode once a year.
This charges the battery at 15V for a short while.

My question to you is should I disconnect the battery from the car to do this? Will 15V damage anything else if left connected to car even though the ignition will be switched off?

If nobody on here has done this yet then I might practice on my wifes car first laugh2

Thanks in advance,
Paul
