DieHard Batteries Reviews

Used to Love Die Hard batteries when Sears sold them. However the current Lawn & Garden batteries are complete garbage, regardless of the Die Hard brand name, which used to mean something. If you get 2 years out of them you are lucky. Last one (3#) I bought crapped out exactly one year from date of purchase. The warranty is 3 months, which should tell you something. I will never buy another one. I used to get 4 years out of a Husky from Tractor Supply.

Bought a Diehard Gold at Advance. Crapped out after only 1 month. They replaced it no problem but now I’m skeptical about diehard. 2013 Cadillac SRX.

Purchased a DieHard Silver and have exchanged it twice within the 2-year replacement warranty. Charging system verified by Ford Dealership as working properly.

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.
