I am sure they work...but over priced for what you get. Compare the following:

Kinetik HC1800 (KHC1800) 1900 Amp 12V Car Audio Power Cell

Max burst amps: 1900

Cranking amps: 1350

Amp Hours: 81

Weight: 54 lbs.

Dimensions: 6-1/2”D x 10”W x 8-1/4”H

DieHard Platinum Automotive Battery - Group Size 34 (Price with Exchange) - Automotive - Batteries - Car Batteries

Group Size: 34

Height (In.): 7.8

Item Weight (lbs.): 53.0

Length (in.): 10.9

Width (in.): 6.8

Power Ratings:

Amp Hours at 20 Hour Rate: 68

Cold Cranking Amps (CCA at 0 deg.F): 880

LOL...The Kinetiks has almost twice as much battery in the same size case for the same $$( actually much less considering no exchange required)

First... the Kinetic doesn't say at what rate the Ah is. Amp hours are not a standard measurement and are sometimes quoted for a different rate. See how the DieHard is listed as a 20 hour rate? The Kinetic could be using a 12 hour rate (which is common to inflate the ratings). Not saying that's the case, but you have to look behind the numbers.

Also, the DieHard lists cold cranking amps. The Kinetic lists cranking amps. There is a significant difference there which is why Kinetic only lists the higher one. "Cold cranking amps" is what the batt can discharge for 30 seconds at 0*F without falling below 7.2v. Cranking amps is the same test but at 32*F. The difference between the two is usually ~ 20%. The DieHard stil falls short, but if you look at the weights and footprints, the Kinetic looks to have ZERO structural reinforcement. You want that under your hood? They stuffed a ton of batt into a thin plastic box. Maybe great for a rear batt, but I'll take the DieHard with a 4 year replacement warranty for under the hood. And I'd get a matching one or two while I was at it because I know who OEM's those Platinums.

I would take the Diehards. 4 year warranty is GREAT. Also, just because a battery seems to have good specs doesn't mean it's actually good. It's the same thing as saying 2 amps that look similar will perform the same.

I understand the warranty issue with buying batteries. I can only speak from experience with the Kinetik..no other battery I have ever owned has lasted almost 5 yrs with a system running off of it. Never had a single battery related issue from it. Certainly not a structural issue, as seemingly implied.

I understand one can speculate all they want as far as the ratings are concerned...but that is all it is, pure speculation. If I walked into Sears and on the shelf sat the Kinetiks HC1800 next to the Sears Die Hard Platinum AGM mentioned earlier for the same price, I would not hesitate to pick up the Kinetik and walk out the door a satisfied repeat customer.....especially since Sears normally sells the Kinetik HC1800 for $315.00 Kinetik Kinetik KHC1800 Vehicle Battery - 81000 mAh - Sealed Lead Acid - 12 V DC--KHC1800 - Automotive - Battery Accessories - Battery Chargers

ps..if Kinetik did use a 10 or 12 hr rate on the Ah, the 20 hr rate will be upwards of 90Ah, based on every other AGM deep cycle I have researched that does provide that info.

It isn't speculation though. Not sure if you meant I was making shit up or not, but if they used a 10 or 12hr rate, the 20hr rate would be lower. Not higher.

Glad you've had luck with Kinetic. I don't care for them though.

By using your prized Odyssey as an example, EVERY single AGM battery they make, except for one (the little PC680, it keeps the same 16 Ah rating for both the 10 and 20 hr) the 10 hour rating is lower than the 20 hour rating....same with East Penn and Concorde AGM's.

I did not say you were making anything up...you were merely speculating that the HC 1800 might not use the same measurement to determine stated Ah as the Sears batt....you were speculating, not me. I see no reason that the stated Ah on the HC1800 cannot be based on a 20 hour timeline. I have not cut the two batteries in half and actually measured the thickness of the casing to determine how thick the Sears is between the ribs, nor how thick the Kinetik is uniformally, but they are tough enough to withstand a proper secure install, as you would do with any battery. OP asked if the Sears AGM was a good batt, I simply stated that they will work, and also pointed out there are far superior available that are designed specifically for the purpose of Car Audio.

Warranty was never brought up in OP, therefore one should assume the question was based on a performance standpoint, in which I care not for a Sears battery either.

ps, Sears does not make a G24 batt in the Platinum, and good luck getting a G34 batt to fit in a Acura

There's a reason my Odysseys are prized. And there is a reason Kinetic has a bad rap. And not just by me. I've used them and they're "ok," I guess. Just another batt. And if you stacked that DieHard up against the hc1800 in a CA app, it might come out ahead. Maybe. And maybe just in a burp situation. As for longevity... I doubt you could beat the DieHard.

What it boils down to is, your vote is for the Kinetic and mine is for the DieHard. That's all. You're a very logical person and I usually agree with you. Just not this time. It happens. Lol.

Odyssey (diehard platinum) uses virgin lead in their batteries, kinetic uses recycled lead. Also, AH is basically useless when looking at effectiveness of a battery for audio usage. AH is a slow discharge rate over long period of time, car audio requires large discharge rate over very short spans.

dude wtf are you smoking.....comparing kinetic to a rebadged odyssey? cmon now you should know better than that. not to mention kinetic uses recycled lead

the diehard is a much much better batt, it even comes with a 4 year free replacement warranty, what other batt comes with a warranty like that?

Yup..I agree about the warranty, no doubt. And also, like I said, my experience with Kinetik has been great considering my purchase was years ago...they might be made cheaper now...I do not know..I am just speaking from my personal experiences.

Odyssey (diehard platinum) uses virgin lead in their batteries, kinetic uses recycled lead. Also, AH is basically useless when looking at effectiveness of a battery for audio usage. AH is a slow discharge rate over long period of time, car audio requires large discharge rate over very short spans.

I agree with the Ah rating...reserve cap is a much more useful rating...but what is your point with the Virgin lead vs Recycled?...and where did you learn this info? link?

obviously not the same shit u been smoking....it does have a good warranty though, if that is where you choose to place your priorities.
