Should you replace batteries in pairs??

THe previous owner of my Ex replaced only one of the batteries. I have been told that if you dont replace them in pairs that the new one wont be able to handle all the draw and both will go dead... ??? I am currently experiencing battery issues.. Charged them yesterday and today when I got home they were dead. One is the original battery...

I say yes replace both. The old battery will pull the new battery down. About a month after I bought my truck I had a battery go bad and as bad as I hated to replace a good battery I went ahead and replaced both.

Always replace in pairs!!! When the new batteries are installed, check to be sure the alternator isn't damaged.

Absolutely. It's not that the new battery can't handle the load by itself; it's the fact that the old battery will pull the new battery down to somewhere slightly above it's own level. They WILL seek equilibrium with each other.

I dont know if you have a Costco near you however i got two 1000 cold cranking amp, 850 cranking amps which have an 8 year warranty on them for $170 yesturday. Also while i was putting them in while still in the parking lot i saw an international truck their which makes me think they make them for costco.
