Sethwilliams88 Posted October 14, 2019 Report Posted October 14, 2019 So i have a new optima red top 34/78 and I just bought an Xs power D 3400. So can I hook those two batteries up in parallel, do I need an isolator hooked up? And do I run a wire to each battery for my alternator I have a high output alternator I just don't know how to hook everything up I've tried looking at other posts and don't understand if one will draw from the other please help
Mike4068 Posted October 14, 2019 Report Posted October 14, 2019 Ooh, that's not a great idea. Those batteries have very different discharge rates. Should be pairing the same batteries, type and age Ideally. Yellow top would be the optima of choice but your better off just getting another xs. You'll run +to+ with fuses rated for the wire capability right after the first battery and right before the second and ground the second battery to frame/chassis.
AaronT Posted October 14, 2019 Report Posted October 14, 2019 They are both technically AGM's, but as said above very different Batts. You can isolate it so they disconnect when cars off, but I'd just get a proper match for xs Even a auto part store agm would be fine for the xs Duracell platinum isn't a bad battery
Sethwilliams88 Posted October 14, 2019 Author Report Posted October 14, 2019 whats a budget friendly batt i can put under the hood

SnowDrifter Posted October 14, 2019 Report Posted October 14, 2019 separately charge each battery, then check resting voltage after several hours. If they're within .1v, just wire as normal. ~~~~~~~~SAY NO TO PHOTOBUCKET~~~~~~~~ Snow's DD-1 tracks here: https://www.stevemeadedesigns.com/board/topic/167433-snows-dd-1-tracks/ My take on OFC vs CCA: https://www.stevemeadedesigns.com/board/topic/110381-things-that-piss-you-off-in-the-car-audio-world/?do=findComment&comment=2461444
