Vented Battery?
I bought a new battery at Walmart. It has what appear to be vents at the sides, see pic. The battery did not come with any vent hoses, and the old battery did not appear to be vented.
My other car is a Miata, and it too has a vented battery, with hoses to an exterior vent. Miata batteries are in the trunk, and people say it needs to be vented to the exterior to prevent gas buildup in the enclosed trunk. I'm not too sure that's a real concern, but whatever.
Should I figure out some way of venting this Wally World battery, or not even worry about it? I can't imagine the engine/battery compartment doesn't vent itself naturally.

apparently its for the newer cars where battery is in a compartment....my C6Z has hoses but then the battery is in a compartment in the trunk....no reason for vent hoses in the C5

On a C5, the PCM, TAC module and a BUNCH of wiring is just about directly below the battery. IF, by some chance that the battery ever over heated or over charged, the ACID that would spill out from the vent tube could fall on to the PCM, wiring and frame below the battery.
I bet you can find a piece of clear Tygon Tubing that would stretch and fit over that vent and you could snake it down below all that critical equipment and allow it to vent/drain on the ground.
That's what I would do.

book is wrong, 75 fits better but CORRECT BATTERY is gp 78 which is what they came with, trash the vented battery and get the right gp 78, ask me how I know, have a c5Z and worked at battery company as well as bought my Z from original owner and org gel battery was gp 78.

He needs to use a 78/34 DT OR a group 34 top post to maximize his CCA/RC, etc.

I just used Wally's battery finder and the 86 is what it told me to use. It fit just fine, no weird repositioning of the battery or cables needed.
To be fair, I just checked a 2003 Vette, and Wally does spec a 75 battery for that year. Again,
seems silly to change the battery type for just one year.

Application listings, be they Wal-Mart, Auto-Zone, Advance AP, etc, etc will usually list the MINIMUM required battery "size" (vis-a-vis Cold cranking Amps, Reserve Capacity, etc) to do the job. If you want the highest capacity, best number of Cold Cranking Amps, etc, get a high quality Group 34 battery.

The higher reserve capacity battery everyone gets their shirts in a knot about being required is only necessary just allows the car to sit longer before the battery reaches a minimum acceptable state of charge. Just regularly drive the car and then it's not necessary to have.

Silly, because changing an item for only one model year--when all other model years of the same generation car have a different part--creates replacement issues, q.v. the other battery types mentioned above.

Then there'd be no "You need part #X for 97 to 98 models, part #Y for 99 to midyear-01 models, part #Z for midyear-01 to 04 models," or something like that.Now, improving a part that fits previous models, that's different, e.g. "Improved part #B, now installed on 00 to 04 models supersedes part #A, previously installed on 97 to 99 models. Part #B may be installed on all 97 to 04 models."
