kinetik batteries

That is why it is important not to mix batteries. Yes it will work for a while, but over time you will see a premature failure of the smaller battery.

That isn't how the charging system works, in the aspect of charging at least. You can go on believing that though.

As for the batteries themselves, they won't have premature failure from charging at 14.4 volts //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif. Put simply, if no music is playing and that specific car sits at 14.4 volts then the batteries will be fine. If music is playing, the car will most likely not be sitting at 14.4 volts as the amps will be drawing power, so they won't be sitting at 14.4...which according to you is "overcharging."

2 different sized batteries will have many differences. They will be fully charged at different times and will discharge differently. The depth of discharge for each action will also be different to each battery. I said this before and I'll say it again pretend you have 2 different sized tanks. 1 that is 10 gallons another that is 20. If they each have a different sized inlet pipe and both have different sized drains how would they ever balance out? When they are at rest (not in use) they will try to and that in effect will drag one or the other down. Sure it MAY last a few years but it wouldn't last as long as a matched up set. Sure even if they were the same batteries front and back the location they are in the vehicle will make them different just by wire resistance or the load that is presented with one being by the amplifiers. Thing is the accumulative effect of adding more differences just makes it that much worse NOT better.

Well it is just no fun when you simply say "that is not how it works" and then do not explain how I was wrong. If you want to be taken seriously, you should do more than simply refute my statement. If I am wrong, then I will learn. If you have nothing to add, I will continue with my way of thinking until I learn otherwise.

I can assure you that if a battery sees a high charge rate well after it is fully charges, it will become over charged at some point in time. Why else would chargers change voltages when it senses a full battery? Why else would charging systems in vehicles lower their voltages when no load is present?

Seems to me there is reason behind why they engineer those systems that way.

Ha, I know what it to be taken seriously. I've been on these forums a while, just left after they went down the shitter. I don't know the terminology, or technical enough aspects of the way the alt-batt system works to refute what your saying. Not a big deal though, I can see in the long run different batteries making a difference, I think we are disagreeing on how much of a difference it will make. It has never been a big concern to me, but if others are buying batt's now, I'm sure it couldn't hurt.

I can see that happening, as my point was never that it was better. In the long run, I can see what your saying happening. I just have never even thought about keeping the same stuff for 3+ years, so it has never been a big concern to me.

There is no guarantee they would even last 3 years. I have seen pretty oddball make shift battery banks last that long but I have also seen them go out in a few months. Hence the reason I said MAY, it may or may not. Depends on how hard they are used.

Are we here to give advice for what might work, or would those seeking advice rather know the right way to do things. Just because someone you know mixed their batteries and it worked does not mean it will work for long. The right way to do it is to have all matching batteries. Same model, same age. As for the difference in distance from the load, you again could isolate the rear bank from the front and properly loading the bank by using the POS+ post from the first battery in the bank and the NEG- post on the last battery in the bank. That should completely balance out the load 100%.
