I have a couple of issues that I would like some input on. In the C5 days, the OEM Delco batteries were known to leak acid (not all of them, but you sure didn't want to be one of the lucky ones) making a mess and potentially causing elec problems. Also, the battery (not a Delco) in my Camaro leaked causing a mess. I did replace it with an Optima red top.

In general, I am leary of lead acid batteries in my cars now.

So - second question: I hear some folks are not happy with their Optima batteries. Is it a longevity issue ? With my C5, I bought an Exide gel cell and it seamed to be o.k.

I've used the factory Delco batteries my entire life on all my cars (including 5 Corvettes). I have NEVER had one leak, not even a drop. They have all provided excellent service and service life.

Almost any battery can leak, the gels are better. I have 2 optima red top batteries. I don't think they are any better or worse than other quality batteries. Considering the cost of an optima, probably won't buy another one. Believe it or not , the sears line of batteries are highly rated, as are exide and delco.

I've had nothing but great service from Delco and Motorcraft. The Delco's in my GMC diesel are 6 years old now.

In our daily drivers less than 3 years in the Vette and 4 in the Silverado, truck went red top Vette under warranty

In short, No and No.

Batteries will leak if they are overcharged and indicates a problem with the charging system not the battery. Any battery that is overcharged is dangerous.

An Optima is a lead-acid battery. It uses more expensive materials than most other automotive batteries that reduce the amount of outgassing. It should longer than a regular battery (maybe 10 or 20% longer) but at twice the cost.

Lead acid may be the wrong term, but aren't optimas gel cells ?

Also, batteries can leak even if not overcharged. Most battery cases have a seam below the liquid line. That seam can fail regardless of charge state. Optimas do not have such a seam.

I agree on the excessive cost of an Optima and not sure if they are worth it.

Same here. The batteries on our 2008 Tahoe and 2008 Silverado both failed. Silverado in warranty, Tahoe, right after warranty expired. I replaced the Ho battery w/ an Interstate. It was pricey too.

However, I am not worried about the Ho, just my "babies", (Corvette & Camaro)

I generally buy Sam's or Wally World, seem to get about 7 yrs. w/ a decent battery.

need-for-speed

Agree. In the past, all I have bought is Wally batteries. If I were to do it over, I would buy a Wally battery for the Ho for about 60% of what I paid for the Interstate.

No and no. There is a tendency here on the forum to favor the more expensive of any options given in a choice situation. I agree that the Optima may be made of more expensive materials or in a more expensive process, but from seeing friends who have them, I don't see a significant increase in lifespan. Remember that simply by manufacturing far fewer of them, the cost will be higher than batteries which are made by the millions.

need-for-speed

I agree on the price thing. Not sure if the Optima is worth it.

My primary motive for the Optima is that it is a gel cell and there is a much lower chance of acid leaks.

Answer to the Lead Vs Gel;

What is a Gel Cell Battery? Is OPTIMA a gel battery?

A gel battery design is typically a modification of the standard lead-acid automotive or marine battery. A gelling agent is added to the electrolyte to reduce movement inside the battery case. Many gel batteries also use one way valves in place of open vents, which helps the normal internal gasses to recombine back into water in the battery, reducing gassing.

An OPTIMA battery is not a "gel" battery or regular flooded acid battery. An OPTIMA is a Spiralcell AGM battery.

Personal experience; my '01 OEM battery leaked at the side posts at 3 yrs and honestly, I really doubt that it was every overcharged or even had an external charger attached to it. Fortunately I caught it just after it started to eat into the computer mounted below....replaced it with a Red Top. 5 years later when I relinquished ownership to a new family, the Red Top was still kicking as good as it did when new.

Anyone want to agree/disagree to the statement that only 2 companies make batteries - Johnson Controls and Exide?

Only battery to leak for me was a Sears Diehard, many years ago.

I've wondered why Delco seems to have moved away from their side terminal battery use. Possibly because the sides terminals were in a position were a leak would be more troublesome, compaired to a top terminal?

The OEM Delco in our 2001 lasted about 5 yrs/55k miles, finally was killed off by an electrical malfunction that repeatedly drained it dead flat. Never leaked.

Each battery is a crap shoot.

At one time, R O Gould made most of all battery labels. Labels such as; Sears, JC Penney's, name brand auto parts stores ect. I think I remember hearing R O was purchased, I believe it was JC's......and we are speaking of just lead acid type here?

Great info Hisvette Thanks!

Stories like the one on your C5 are what I remember ! That is why I replaced the OEM battery in my C5 with an Exide. And I beleive it was the same design as an Optima. Good to hear on the 5 y.o. red top.

need-for-speed

That probably sums it up best

need-for-speed

I have heard that Exide makes many of the different "brands" out there.

I've always used Delco in my vettes never had a problem.

IMO Optima's (especially Redtop) are Garbage. Every person I have known that has used one has had problems...you can't even let the car sit a week or 2 without having to put it on a tender. Not acceptable.


When my Delco on my C5 finally went (it last 6 years) I switched to an Excide Orbital and that was still gonig strong after 3 years when I sold the car.

Stay away from optimas they are not worth it.
