CTEK.. battery reconditioning..Pass OR Fail???

please see previous video..

3 days later...

its a ....

FAIL!!

the CTEK charger could NOT recondition my 90Ah AGM battery from my Discovery 4 LR4.

Next... I will try an 'old fashioned' battery charger that has no fancy electronic trickery..
will it work?????

I've got the same model of CTEK. On a regular battery (which would not hold charge for more than 3 days) I used the charge mode, got it to full but it would drop SoC repeatedly (as in 7% every 1hr in cold weather). I then ran the recondition mode and after 10 hours, the battery is on 99% SoC and 12.78v. Temps have risen slightly where I am and I'll check tomorrow morning but it does seem that the CTEK Recond mode does indeed work, or at least buys you more time before needing to purchase a new battery. I have a battery monitor permanently wired to the battery also which measures SoC, Temp and Voltage which will of course go towards using some of the charge.

From various manufacturers including CTEK, my understanding is you need to FULLY Charge the battery (If possible) before you do any Recon cycle. And if the test shows it isn't yet viable to be used, you can repeat the process again and again to gradually reach better results. Just one cycle through Recon mode without a full charge in the cells is not going to be effective.

Is it normal for the red light to be on if the battery is not connected?

Mine just added 24 CCA ( from 141A to 165A only ) what a snake oil recond mode thing

I have Ctek charger. You are supposed to run the recon cycle periodically throughout the life of the battery. You can't wait until the battery is bad to try to recondition it. Plus, you are supposed to run the regular charging cycle on the battery first. If the battery will take a full charge, THEN run the recon cycle. This keeps the lead plates desulfated regularly and the battery working properly for longer. That's my experience.
