INOX Battery conditioner

I put Inox into my present Overlander 700CCA starter battery in 2003, and in 2004 I also connected a "Megapulse" system to it. It's now 4 years old and does not give me any problems, but I’m not aware which system is working better for the battery.
I also have a new series 3 Megapulse system connected to my 2 x 80 A/H DC batteries and they are at least 4 years old also, and still in 'perfect working order' as they are tested by a competent battery specialist annually.

The technical information available for the Megapulse from the distributors on the East Coast is very easy to understand and makes sense to me, that’s why I bought the second unit, my Steca solar regulator also uses a similar PWM system.

Reiner,
Charge it up then leave it for a day or so, then connect the light and check the voltage at regular intervals, writing down the results and the times.
Then add the inox, leave for a few days exactly as before, fully charge the battery as previously and then connect the light the same number of days later and check the voltages at the same times as previously...

Sure it's a pain doing things exactly the same both times but anything else is only going to give you a rough result that can be questioned and not relied upon.... as I said it is a pain, but rewarding when you get results that can't be disputed because you have checked the battery at different times or had a different load at the start, and yes, I am very interested in the answers :-)
