Adding 2 new cabin batteries

Recommended Posts

My 2001 Holiday Rambler Ambassador came with 2 6 volt cabin batteries and now I'm adding 2 more 6 volt batteries for a total of 4. I'm adding a 1500 watt inverter also.  Should I wire the new batteries together or mix a new one with a old one? The 2 old batteries aren't that old and are working great so not going to replace them. Thanks for the input.

You would do better to replace the 2 existing batteries with new ones because they will pull the new ones down to their level.  Chuck B 2004 Windsor

I would agree. Unless they are fairly new or at least in excellent condition it can be counterproductive to mix old and new batteries.

Check the resting voltage of the old batteries after a full charge and same with new batteries. If the difference is less than .25 V then I would use them. When I have a battery failure due to a bad cell I don't automatically replace all. 

I  agree with with Gary also. Resting voltage will be after fully charging then no charge or discharge for at least an hour.
