DieHard Batteries Reviews

OE battery in my Audi finally died, lived in small town and Advance Auto was the only parts store. They sold me an undersized H8 AGM rather than ordering the H9/95R size of the OE battery. It died in a year. They replaced with another H8 AGM, which died before hitting two years in car. I reminded store rep that the H8 is undersized for my vehicle and not the factory-sized battery, which is 95R/H9, so he did the right thing and ordered the H9 AGM, which is not typically shelf-stocked in any parts stores I've checked. The H9 Platinum AGM was great until a big polar vortex -15 F temps overnight, and since has not been holding charge. Use an automated trickle charger just to keep it going. Still under warranty too, as I had to pay some towards the final battery, as pricing had changed since bought first battery, but the battery tests fine and test report just says it needs to be charged...yeah, right.

Bought DieHard from Advance Auto in May for a 2019 Subaru Legacy. It died in July. Had car towed to mechanic to make sure no electrical drains. Advance said it was bad coil and replaced free of charge. Now new battery dead again. Will get my money back!! No more DieHard! Bad product!

The battery lasted about 2 years. It died without warning. I bought Diehard from Advanced Autoparts. DieHard were reliable batteries back in the day. It is not a cheap battery either. Not going buy it again.

Obviously they don't trust the quality of their own batteries since the warranties are non-transferable when a vehicle is sold. Sounds like a cheap way out to me. Will never buy another DieHard battery again.

In November, 2024 I bought a Diehard gold for my Porsche. After a short time it began to die. Initially I thought it was due to not driving the car far or everyday. Eventually, Feb 2025 I returned the battery to the store and the test showed it would not hold a charge. Also I notices corrosion at the bottom of the tray. Today, April 2025, I had to replace the battery again. When I took the battery out there was more corrosion and you could see fluid leaking from the top (side) of the battery. The store gave me a new battery from a different batch. However at 229.00 this is ridiculous.

Diehard Sucks. Three replacements in a year! Left me stranded, just dies out of the blue without warning. I bought Diehard for many years when I was younger & never had a problem. Now they just aren’t any good. Never ever buy a Diehard unless you like being stranded & inconvenienced several times a year!

I'm still under warranty for my Die Hard silver car battery. I have two of the same cars so it's easy to test one against the other. I put one battery in both cars and it starts both easily, repeatedly. Put the Die Hard in and neither car starts. Both vehicles run without the battery connected so both alternators are good. Both vehicles start ten times in a row at operating temperature so both starters are good. The Die Hard battery fails to start either vehicle. The other battery starts either vehicle a dozen times in either car so it can only be the battery. The Die Hard battery passes the test at the parts store but it won't start the car twice in a row. There is an internal malfunction that isn't registering on the test cycle so the store cannot replace the battery. So I'm out of two hundred dollars with no apparent recourse. You tell me if you want in on this conundrum.

In the past fifteen years, I have bought two Die Hard batteries from Sears that were bad right out of the box - wouldn't take a charge. More recently, I bought a Gold and a Silver for my RV and boat, and both of them crapped out right after the warranty period, about 13 months. As a baby boomer, I grew up with a father who was a Die Hard die-hard, but they are not what they used to be (what is?).

I once was a believer of Diehard Batteries because of their durability. My mind has changed after replacing 4 batteries in 2.5 years. Remember, the replacement date will expire from the date of the original purchase of the first one. The 3rd battery lasted 2 years and 2 months. Yes, it was a Silver Diehard Battery. 2 years of free replacement. Nothing longer. I'm no longer a believer in using Diehard Batteries.

Bought one platinum DieHard battery and it lasted 5 months. I returned it and had to pay for a secondary warranty and got the secondary battery replacement and it lasted 6 months. Just returned secondary battery to get 3rd replacement, now I'm given the marine battery and they told me I have to drive the car once a week at least to keep it charged. This is the first time I ever had such a battery issue. Next battery I'm going to buy a better brand as it's not worth the time lost needing the car to work versus it being dead alone needing its use. Overpriced battery but it did die hard.
