Battery: 94R-850 vs. 49-950
It's hard to believe, but my car almost 5 years old now.
Since it's not garaged and Florida's heat is very hard on batteries, I figure I should replace the battery soon as preventative maintenance. So, I've been doing some research. OE replacement is 94R-850 https://www.odysseybattery.com/produ...ttery-94r-850/ Optional (convertible?) is 49-950 https://www.odysseybattery.com/produ...attery-49-950/ I would prefer to use the 49-950 because of the higher CCA and Reserve Capacity; however I don't know if there would be any issue with fitment (1.5 in. longer) or registration. A few questions: Will the 49-950 fit, register and function without any modification or issue? Some battery descriptions/specs include the note "with SAE posts". Do our batteries have SAE or metric posts? TIA.

I searched before posting my query but didn't see those posts you linked to. The ODYSSEY 49-950 seems to be the way to go. I'm willing to accept the +6 lbs. in the trunk. It will get me a little closer to a 50/50 weight distribution. Edit: FCP has it for $264, with free shipping. That's pretty good. I was considering waiting another year (6 years old), but may just go ahead and do it now.

I installed the Odyssey 49-950 (ODP-AGM49 H8 L5) battery today. It turns out the car had the larger 49/H8 battery in it, from the factory. So, I'm glad I got that one.
I registered it with Carly as the "same battery", because it was the same "series" (49/H8). But, I noticed that all of the specs (CCA, RC, etc.) were higher than the original, including 94 Ah, vs. 90Ah. Should I have registered it as a "different battery"? If so, what?

A new batteries is registered to tell the intelligent charging system (ha!) that car now has a new battery. The ICS then uses a different charging profile because the battery is new.

Yeah, I'm just wondering if I should have registered it as a "different" battery because all the specs on the Odyssey battery are a little higher than the OE battery.

Type is the same (AGM), but the new one is 94 Ah, vs. 90Ah for the OE. I think I'll go back into Carly and see if there's a "different" setting that matches the replacement specs and if there is, I'll change it.

Register & Code
When you get a new battery it is important to register the new battery.
. Then, if the specs are the same -- you are done. . If the Specs are different then you need to Code the car for the specific change. . My old battery was 90ah and new was 92ah (no change / coding needed due to being within the range) If my new battery was 94ah then I would need to Code the change. |
