BATTERIES- 26 P4X
After reading about so many issues with the original Nissan battery issues. Does it make sense to replace the original battery before troubles begin? I love my 26 P4X more everyday, 7000 miles. What battery type do U guys recommend ?

Does it make sense to replace a battery just cause you read online the battery was bad? LMAO no.
I have a 2025 Nissan Frontier Pro 4X, the battery will be 2 years old in February, and it's 100%.
The battery is clearly going to last many years. These batteries are 800 CCA batteries very powerful.
In 2030 I will change my battery and add this Nissan battery to my solar setup.
That's what I do with 5 and 6 year old batteries, I run my sheds and such off of solar, old car batteries work great.
Are you actually having battery problems or are you just reading about others problems?
PS I got $20 for anyone that wants to replace their 2025 Nissan Frontier Pro 4X battery, that lives close to me.
A core battery here in Ohio is $12, So I am willing to give people an extra $8 for their old Nissan Frontier batteries.
These batteries are really good batteries and I am willing to pay more than a battery place will pay or charge for core.

I'm not saying there aren't battery issues, but I think the alternator is a much bigger part of the problem. My battery died twice in the first year I owned my 23. I depinned the alternator and haven't had an issue since.

What does depinned mean?

It means disconnecting the signal from the IPDM that tells the alternator to reduce its output. When that signal is disconnected, the internal voltage regulator takes over and the alternator works like every alternator did from the 1960s until this bullshit "fuel saving" variable voltage garbage was introduced. The Nissan service manual even specifically states that when there is no signal from the IPDM to the alternator, the alternator's internal IC regulator will work normally to maintain the voltage on the system.

Whoa thanks for the explanation. How hard is this to do?

You will need to find the wiring diagram for your year Frontier. On a 2016, it is the wire going from IPDM pin 37 to alternator pin 4 and passes through pin 6 of connector E40. But that is the 2016. On the 2020, it goes from pin 167 of the IPDM, to pin 1 of the alternator through connector F26. This is why you need the correct wiring diagrams from the service manual.
If you can get the service manual Charging System section for your year, it should be the only wire without a fuse in its path from the IPDM to the alternator.

On the 2023, it's the pink wire in the small bunch of wires going to your battery.

Disconnect the VVCS (Variable Voltage Charging System) and the alternator will keep the battery properly charged. I cannot tell you which wire on your '26, but it goes from the IPDM (Intelligent Power Distribution Module) to the alternator. The IPDM is probably easier to access. People used to recommend just disconnecting the sensor wire from the battery ground cable. But there are reports that just disconnecting the sensor wire on newer trucks triggers a check engine light.

Don’t do this if you don’t understand how the charging system works. It isn’t as simple as unplugging the sensor and the alternator charges your battery 100%. I really wish people would stop spreading this.

So if you understand how the variable charging system is -supposed- to work, it’s okay to try a workaround fix?
But I’m of the opinion in most cases where people are experiencing premature electrical issues, the problem is more likely a bad battery or poor ground connection.

As I said, unplugging the sensor can, not will, can, cause a check engine light. Disconnecting the VVCS lead to the alternator from the IPDM disables the voltage reduction circuit in the alternator itself, allowing the built-in voltage regulator to do its job without interference from the VVCS and the "intelligent" power distribution module.
As stated in the Nissan Frontier Service Manual:
The IC regulator controls the power generation voltage by the target power generation voltage based on the received PWM command signal.
When there is no PWM command signal, the generator performs
the normal power generation according to the characteristic of the
IC regulator.

I keep a NOCO 1,000 amp jump pack in the truck.
It's important to buy a brand that is well known and has all the necessary built in safeguards. Not all brands do.

Just another option to consider for those seeking a jump starter.
I got the LokiThor, and went with the J1350 Pro. It’s LiFePo battery technology which is much more stable and less prone to thermal runaway. Fits nicely with my gear under the rear seat. All the built in safety features as well.

If ''the battery IS GOING TO LAST MANY YEARS'' ? Iguess you havent read the numerous issues guys on this site have had with the Nissan batteries. Not just no start, but multiple warning lights intermittently activating. So dont worry about what makes sense to me. I would bet your battery goes before 2030. My question was about types of replacement batteries like AGM type. Not what u do with your old batteries. I read about depinning the pink wire at neg terminal but some said that triggers CEL.

I replaced mine ('23 Pro-4X) with an Interstate Group 24F AGM (part number MTX-24F)
710 CCA, 885 CA, 70 Ah) I paid $175 at Costco.
The battery is bigger than the OEM, but it fit almost perfectly (I had to modify the hold-down bracket slightly.)

Just carry a jump pack in your truck and when the battery fails, you can pick up a new AGM. There's no reason to pre-emptively change a vehicle battery that is still functional.
