Which Optima red top part number with vent?
Which Optima red top part number with vent?
Hey guys,
Mostly lurker never post much. But I finally had the old Panasonic crap out on me, and I am interested in getting the Optima red top that the dealers replace them with, but don't want to pay the dealer price of like 343 they are asking for.
But I'm stuck on a part number. The dealer tells me that the Optima they use is a group 34. They don't have an 'Optima' model/part number to give me, only Mitsubishi part#ALE08FB1X0( I have a 2008 gsr).
I then checked Optima's website, but based on the options I have to choose from, it says 35. However it only lets me choose lancer, and not an option for evolution. I then called Optima, and was told the 35 does not have a vent.
I've seen pictures of evo x trunks with Optima red tops, and some of them I can see the vent tube connected, some not.
I've checked all the threads I could on here and on evo x forums, but no one really addresses the vent.
Can anyone out there running a red top Optima WITH their original vent tube let me know what model battery? Is it indeed a 34 red top? All I seem to find is a 34/78 red top.
Thanks

Edit: Considering many other forum members may see as well, I want to add a little background. In fact, Optima does make a vented Group 35 specifically for the Evo, but they don't sell it through their battery dealer network. They sell it exclusively(?) through Mitsubishi dealers, so they can together rip us off.
This is been discussed previously in detail:

But anyway, if you have a 15v situation, you have some other problems to worry about.

I'm also interested to mention that recently some guys have figured out rather simple ways to vent AGM batteries:

I'm very excited to looking into custom-venting an Optima Yellow Top. Hopefully OP can figure out a way to custom-vent the Optima Red Top too!

lol.
Dealership replaced my panasonic battery on my 2008 gsr with a non vented optima red top in 2010.
I don't see any reason to go vented? Just save the money and buy a non-vented one.

All lead-acid batteries are vented. Even AGM batteries - they have emergency vents because although they don't vent in normal use, they'll vent if overcharged. If you go with a 34 series battery, it has a vent with a tube attachment, so the flammable and explosive gases are vented outside of the vehicle. If you go with a 35 series battery, it does not have a vent tube attachment, but it still has vents, which would vent the flammable and explosive gases into the trunk and passenger compartment.

I know this is an old thread, but it is being linked to so it's worth updating.

Are you sure switch from a Group 35 to Group 34 will get you the ventilation port though? I checked some Group 34 batteries (e.g. https://www.optimabatteries.com/en-u...le-battery/d34 ) and they don't seem to have the port.
Edit: Optima indeed asked that "If your battery is mounted inside the passenger compartment, the battery must be vented to the outside of the vehicle:"
https://www.optimabatteries.com/en-u...optima-battery
Hello, I noticed your conversation and wanted to offer some assistance. Even though our batteries have a “sealed” design, all lead-acid batteries can vent gas. Under normal operating conditions, an AGM battery will not vent gas. Since alternators or chargers can fail, the safest and correct mounting method for trunks and passenger compartments is to make sure that any possible gas venting will escape to the outside of the vehicle. All vehicles with original equipment battery locations in the trunks or passenger compartments will have a vent provision that should be used.
Our group 27, 51, 34C, and 31 batteries all have ports for connecting a vent hose. Although people do it anyway, we would never recommend installing an unvented battery in any enclosed space, because there's a legitimate, albeit unlikely, safety risk involved.
For example, IF there is a voltage regulator failure, and IF the battery is severely overcharged, and IF this goes unnoticed, and IF the battery vents because the internal pressure exceeds the release pressure of the vents, the gasses are both flammable and toxic. This may sound like a lot of “ifs,” but attorneys and engineers get paid to plan for every worst-case scenario. If anyone has any questions about our batteries, I'll do my best to answer them.

I have also found more useful information regarding the hazardous gases of lead acid batteries:

...
Negative plate reaction:
Pb (solid) + HSO4– (aqueous) → PbSO4 (solid) + H+ (aqueous) + 2e−
Positive plate reaction:
PbO2 (solid) + HSO4– (aqueous) + 3H+ (aqueous) + 2e− → PbSO4 (solid) + 2H2O
The total reaction can be written as:
Pb (solid) + PbO2 (solid) + 2H2SO4 (aqueous) → 2PbSO4 (solid) + 2H2O
During charging, (especially in the event of overcharging), lead acid batteries produce oxygen and hydrogen. These gases are produced by the electrolysis of water from the aqueous solution of sulfuric acid. Since the water is lost, the electrolyte can be depleted. This is why you need to add water to “wet” (flooded type) non-sealed lead acid batteries. When a lead acid battery cell “blows” or becomes incapable of being charged properly, the amount of hydrogen produced can increase catastrophically:
Water is oxidized at the negative anode: 2 H2O (liquid) → O2 (gas) + 4 H+ (aqueous) + 4e−
The protons (H+) produced at the anode are reduced at the positive cathode: 2 H+ (aqueous) + 2e− → H2
So, in an area where lead acid batteries are being charged, the first gas to measure is H2.

Ventilation
Charging batteries in living quarters should be safe, and this also applies to lead acid. Ventilate the area regularly as you would a kitchen when cooking. Lead acid produces some hydrogen gas but the amount is minimal when charged correctly. Hydrogen gas becomes explosive at a concentration of 4 percent. This would only be achieved if large lead acid batteries were charged in a sealed room.
Over-charging a lead acid battery can produce hydrogen sulfide. The gas is colorless, very poisonous, flammable and has the odor of rotten eggs. Hydrogen sulfide also occurs naturally during the breakdown of organic matter in swamps and sewers; it is present in volcanic gases, natural gas and some well waters. Being heavier than air, the gas accumulates at the bottom of poorly ventilated spaces. Although noticeable at first, the sense of smell deadens the sensation with time and potential victims may be unaware of its presence.
As a simple guideline, hydrogen sulfide becomes harmful to human life if the odor is noticeable. Turn off the charger, vent the facility and stay outside until the odor disappears.
Caution:
When charging an SLA with over-voltage, current limiting must be applied to protect the battery. Always set the current limit to the lowest practical setting and observe the battery voltage and temperature during charge. In case of rupture, leaking electrolyte or any other cause of exposure to the electrolyte, flush with water immediately. If eye exposure occurs, flush with water for 15 minutes and consult a physician immediately. Wear approved gloves when touching electrolyte, lead and cadmium. On exposure to skin, flush with water immediately.

Autozone
I know people will say otherwise but I replaced my OE battery with one from autozone with no vent.My car has yet to catch fire or blow up from gases in the trunk.I've had it over 2 years. It's my daily so I take care of it.
