NorthStar Group 27F Battery (MODEL: NSB-AGM27F) for the 5th Gen 4Runner

NorthStar Group 27F Battery (MODEL: NSB-AGM27F) for the 5th Gen 4Runner

After owning my third 5th Gen 4Runner, it’s becoming a well-known fact that the factory batteries arent meant for running many extra accessories.

In a previous article, I talked about replacing and installing a battery along with voltage readings on the Panasonic battery after about 3.5 years and 30K miles. That article covered the basics of installing and replacing your battery along with in-depth information on the Odyssey Group 34 battery.

In another article, I talked about everything you need to know before buying a battery. That article is more or less a “what to consider when shopping for a battery upgrade“.

Now the time has come to replace our battery in Jade, our MGM (Metal Grey Metalic) TEP (Trail Edition Premium) 4Runner. Jade is a 2016 4Runner with 41K miles.

Time to Replace Your Battery?

5th Gen 4Runner OEM Battery

Batteries have been known to last well beyond the three-year mark. If you reach deep in the forums, some guys even claim 8 years on the factory Panasonic battery. However, you can bet that they were not running many power-hungry aftermarket accessories like a Fridge, Winch, LED light bars, LED fog lights or even common LED/HID headlights.

The battery on our MGM 4Runner was starting to become quite sluggish and took longer than normal to start. This was the exact sign and symptoms of both my 2014 and 2015 4Runners. The Panasonic battery wouldn’t start the 4Runner if the LED headlights were left on for longer than 5-10 min. Thankfully, we have a couple of battery jumps like the NOCO GB40 laying around. If you don’t have one of those, I highly recommend one, with or without a new battery.

Battery Jump

We could probably pull another year out of the factory Panasonic battery if we wanted to, however, we have many aftermarket lights and accessories going. With a new AGM battery, we can rest at night knowing that our 4Runner will have the power it needs to stay on the road, and power the accessories we are about to install on it.

Factors that affect your Battery Life

Battery Options for the 5th Gen 4Runner

  • Short Trips prevent batteries from fully recharging. Frequently taking short trips can shortening your battery’s life expectancy.
  • Extreme Temperatures have a very negative effect on batteries. Extreme heat and cold can really shorten a battery’s life expectancy. If you can, try to garage your 4Runner in these severe conditions.
  • The climate contributes to your power degradation. Depending on where you live can have a big impact on the lifespan of your battery. Check out this map for reference points.

NorthStar Group 27F Battery or Odyssey 34R?

5th Gen 4Runner Battery Replacement Guide

So why the NorthStar 27F?

To put it simply, I wanted something different than the Odyssey Group 34R I already purchased for the other 4Runner.

I was looking to go with the most power possible while not having to extend my power and ground cable to reach terminals. Sometimes it’s nice to keep it simple and just drop in a new battery. That’s it. No spacers, no wire extensions, just a good ol’ 10mm and done.

I was perfectly happy with the Odyssey 34R but its always nice to have more power, all while having fewer parts.

NorthStar Group 27F Vs. Odyssey Group 34R Fitment

The NorthStar Group 27F is taller than the Odyssey Group 34R. This is nice because you don’t need to add a spacer in order to get the battery to match the terminal height, like the Odyssey 34R. 

For the Odyssey 34R, you will place a spacer on top of the plastic battery tray and then set the battery on top of the spacer. See that here.

For the NorthStar 27F, just remove the plastic battery tray and place the battery directly on the sheet metal. 

Because the plastic battery tray is just short of the NorthStar 27F length, they don’t line up. The fix is simple, just take out the battery tray. The battery is held in place by your battery clamp alone.

Both of these batteries take up nearly the same amount of space in terms of cubic feet but the NorthStar 27F has higher CCAs and RC than the Odyssey 34R.

One of the biggest selling points of the Odyssey 34R was its weight. Sitting at only 50lbs, it comes in at 17lbs less than the NorthStar Group 27F. If weight is on your mind, then you may want to consider the Odyssey Group 34.

Because if you don’t know by now, weight is the enemy

NorthStar Group 27F or X2Power Group 27F AGM?

NorthStar Group 27F or X2Power Group 27F AGM?

NorthStar Group 27F is basically identical to the X2Power Group 27F AGM so who wins this battle? On paper, these batteries literally have the same exact specs. And, if you look more in detail at the X2Power batteries you will find that they are in fact manufactured by NorthStar (USA Made) as a white label brand for Batteries Plus. What I found interesting when shopping around is that I was able to get a NorthStar battery on Sale Amazon for less than the X2Power which is typically known to be a bit more affordable.

The choice came down to these two options and I pulled the trigger on the NorthStar for around $329 on Amazon. Regardless of which unit you choose, you are likely getting the same product and if you buy an X2 battery from Batteries Plus they have a great (60 Month Free Replacement) warranty.

Final Thoughts?

There is not much to review on a battery out of the gates. I will find out what the lifecycle really proved to show 60 months from now.

Whether you choose NorthStar, X2, or Odyseey – you are likely to see great results.

Over the last year, my Odyseey group 34 has powered everything I’ve asked it too. What I did find interesting though is recently I left my white 4Runner in the garage with the Odyseey for about two weeks without a start. Upon starting the 4Runner, it did give me a tiny bit of hesitation. I didn’t think it would show signs of fatigue that early.

As long as the alternator keeps that battery charged though, it’s lightning-fast to start. In fact, I have noticed that the Odyseey provides power faster than the brand new NorthStar even though on paper, the NorthStar has better specs.

Again, I think the real debate will come down to 3-5 years of consistent use on both of these batteries to really gauge how they hold up.

In any case, I think the NorthStar, X2, or Odyseey batteries are all going to be good options. Just personal preference and hopefully you can find a deal on one of them when you wake up with a dead battery in the winter.

It’s nice to run the NorthStar 27F and the Odyseey 34R for a real in-depth comparison down the road.

I was a bit confused about this article. It didn’t make sense to me that “The NorthStar Group 27F is bigger than the Odyssey Group 34 but the nice thing is that you don’t need a spacer. Just remove the factory battery tray and drop this NorthStar Group 27 into place. Both batteries take up just about the same amount of space in the battery tray” A) If the tray is taken out, how can the Group 27F “take up just about the same amount of space in the battery tray? B) Without the tray how is the battery held… Read more »

I’ve got a few things I’m trying to figure out: 1) What is a safe weight battery, without having to worry or buy a special cage to hold it, and not fatigue/crack the metal over the wheel well? This would be with normal average 4-wheeling (not racing or jumping around on rolling fire roads). The Northstar / 2XPower 24F is 57 lbs. The 2XPower 27F is 68 lbs. The Odyssey 34R is 50 lbs. 2) It feels weird to mount a battery (27F) just sitting directly on the sheet metal. The plastic tray has alignment pins into the sheet metal… Read more »

I would not run mine without a tray so when I did my X2Power 27f swap I used the battery tray from a Tundra which comes with a 27f. Toyota part number 74431-0C020. It fits perfectly.

So I have for about 3 years now been struggling with a need for power, for my 2016 quicksand TRD Pro. I am currently using a monocrystalline solar panel I can’t recall right now with the wattages on it but it’s like a hundred and 80 Watts or something I think, along with the RedArc charge controller with dual batteries. I have an odyssey 34 series as my auxiliary battery and I forgot the brand that I’m using for my house battery. My LEDs and refrigerator as well as heaters for my water tank for the winter time (I clean… Read more »

It sounds like your heaters are causing the issue as they use a lot of power and you probably need to add another battery or two.
