My Experience With Diesel Pickup Truck Batteries (Don’t Make The Mistakes I Did - They Can Cost You)
When I purchased my first diesel truck which was a 2008 Ford F-250 6.4 Diesel I learned a few things - fast. About a few weeks after driving off the lot the batteries went out. My first mistake was letting the dealership put two of their cheap batteries in the truck under “warranty”. It was just a little under a year that the batteries went out, and took the alternator with it (in smoke). If you do not know by now, a cheap battery can take an alternator out quickly.
If I would have invested the money in the first place for a higher end battery, I would have saved myself the trouble of buying more batteries and not have had to replace the alternator.
I ended up buying two AGM batteries for my truck. Why AGM batteries? They deliver in dependability and cold cranking amps. Since investing in some quality batteries, I have not encountered any additional battery issues. When I have customers ask me about replacing diesel pickup truck batteries I highly suggest an AGM battery. It may be more expensive, but it pays off in the end.
Invest In AGM Batteries for Your Diesel Pickup Truck
The AGM batteries we sell average about 50 - 60 pounds and will be dependable for years to come. The weight of an AGM battery is roughly 30 - 40 % heavier than that of a conventional lead acid battery. When it comes to well maintaining your diesel pickup truck this will keep you on the road for several years. Simply, if you can afford AGM batteries - do it.
Always Replace Both Diesel Truck Batteries at the Same Time
Batteries in a diesel truck usually require replacement at the same time. When one battery begins to fail this causes more stress on the other battery In most cases you will not know there is a problem until both batteries have already failed. We have had customers who have replaced only one battery to have to replace both again in a few months. Do it right the first time.
Can I Put Conventional Lead Acid Batteries in My Diesel Pickup Truck?
The answer to this question is it depends. Most manufacturers put cheap conventional lead-acid batteries in diesel pickup trucks to keep the cost down. That battery will allow you to get off the lot (in most cases) and down the road for a little while. In most cases, yes you can put a conventional lead acid battery in a pickup truck. Before you do so - check with the manufacturer to see their recommendations.
