mixing batteries with same voltage but different reserve capacity?

[Kevin M]

It came up when I was surfing and really couldn't find the answer on my own so I decided to make a thread about it. Let's say I have 3 hc600's and one hc1400. Is it optimal to run them together? Is there any dangers providing that they have the same voltages? I think I have seen it done before but is there any actual danger to the batteries? I feel like I should know the answer to this but wasn't 100% sure.

no problem......a vast majority of people run different sized batteries together

it's different types where you can run into a problem

That's what I figured. I just needed some conformation. Thx

You will be fine.

The only thing you dont want to do is run 12 volt batteries with a 14 or 16volt battery, or run 12volt agm batteries (such as xs power, linetik, stinger, batcap, etc) with lead acid batteries (typically what comes with your vehicle). Since the lead acid batteries are not as strong and normally have a much lower resting voltage which will cause the lead acid style battery to drain your nicer agm batteries until those agm batteries are resting at the same lower voltage as the lead acid.

Thx. I actually have those 4 batts in the garage and my brother wanted me to put them in his car so I thought I would ask just to be sure. I have a couple deka intimidators in the Malibu.
