Cold crank amps and jump battery requirements?

uncompromise

Adventurer
Been digging into jump packs, and learning that the primary requirement is a battery that has the required cold crank amps for my vehicle. Seems most jump battery manufacturers don’t include this information in their data sheets, going instead with the more simplistic “will work with x litre gas / y litre Diesel engine.”

I’ve been looking specifically at Noco given the consistently high reviews, but can’t seem to find the CCA data for their jump kits - unless the amps of each kit are the CCA (in which case hopefully somebody will tell their marketing Dept).

According to the owners manual, the CCA for my 2004 Pajero 3.2 DiD is 620. Noco has a 1000amp jump kit, and a 1500 amp kit that is double the price. Their website says that the 1000 amp is for diesel vehicles up to 3l, which makes it seem like I should be buying the 1500. But if my CCA requirements are only 620, shouldn’t the 1000 amp kit do the job?

Additionally, should I be considering upgrading the current 620 CCA battery to something larger? I appreciate a lot of this has to do with how we intend to use the onboard power, but since we’re planning to build an auxiliary power system to take care of our off-grid power needs, the starter battery will generally be used only for that.

I bought the Noco GB70 and the Noco GB150, I would forget all the other models and go straight to the GB70 because these two models are the only ones in the range that you can use them to power your OBD Port whilst removing or Charging the Vehicles battery This way I don't loose any of the vehicles settings or have to retune the Radio, Not only that when you changing the battery in some modern vehicles every time you change the battery you have to program the Vehicles ECU/BMS to let it know what battery has been fitted This is a real PITA with modern VW's or use them to power your fridge up to 4 hours,

I gave the GB70 to my brother because he was having trouble with his 2017 VW and needed to charge and replace the battery and I have used the GB150 every couple of weeks since the Lockdown in order to recharge my Van/Campers Battery because the computers in the Van slowly flatten the battery when it sits doing nothing for weeks on end,

The little Noco GB40 will start most things but the GB70 and the GB150 give you so many more options that I would not consider any other models or brands on the market and they charge pretty fast too,

Hope that helps.

Noco didn't fare so well in this test



I have the gb70. It's rated for 6 liter diesel. It will not start my 7.3 diesel. It has started my 4.0 gas Jeep

How can you say that the Noco didn't fare so well when the clown in the Video never even charged it up and has below 12v, I also have the GB40 and after sitting idle for over 6 months it still has over 12,4v in it, The one in the Video had 11.9v, I would hardly call that a fair judgement or a fair Test.

As for your GB70 then it is working correctly as it is rated for and up to 6 Litre Diesels and 8 Litre Gas Engines, If you need one to start bigger Diesel engines than 6 Litre then you need the GB150 because they will even start a Peterbuilt, There are quite a few Videos of the GB150 starting proper Truck on Youtube.

I haven't watched the review video in some time, but I am surprised to hear that the tester did not charge the Noco before testing. I watched some of his other videos and he is typically very meticulous and accurate in his testing.

I do NOT know if my GB70 is working correctly. I do know that it was able to start a 4 liter gas engine on one occasion and not a 7.3 diesel. That is what it is supposed to do. I have not done extensive testing on it or tried it on an 8 liter gas engine, so I have no real way to know if it is working correctly as you suggest. It has done some things as expected, but I can't conclusively say it is working correctly.

Cool, I bought the GB150 first and then I bought the GB70 as a backup but ended up giving it to my Brother because his GB40 could not be used to power the Cars OBD Port like the GB70 and the GB150 can, If you have any vehicles that have the ODB port it is worth you getting the Noco OBD Cable because it does save you a lot of messing around when charging the battery or swapping them out,

Another thing you must remember when doing this is the NOCO GB70 and GB150 have a Timer and they will only power your OBD port for "7" Hours so if your battery charging takes longer you will have to hook up your battery to the Vehicle again and switch off the GB70/150 for a few seconds then switch it back on again and then disconnect your battery then put it back on Charge again just so it can finish Charging, But what ever you do when doing this REMEMBER the 7 Hour Timer Limit, Ok.

Hope that helps.

The "keep your ECD and radio presets powered" is a pretty cheap and simple gadget worth buying separately I'd think.

Some used to use a fresh 9V "radio" battery, as in from the grocery store?

That's a good idea, I did think of buying just a spare NOCO Lead and a small 12Ah Battery then I would have enough power to last the OBD for a few days, I think both could be bought for about 30 or 40 bucks problem solved Ay,

I've owned a Noco GB40 for 4-5 years. It works just fine for gasoline engines of all sizes and holds its charge for at least 6 months (I recharge every 6 months if the unit has been idle, otherwise I recharge it shortly after each use.) It has never failed me.

Knowing what I know now, if I were buying today I would probably buy the GB70 for its increased capacity although I don't need that extra capacity to jump start anything I own.

As noted above, for a unit that will reliably start 7 liter+ diesel motors get the GB150.

Thanks for all of the responses. My 2004 Pajero is a 3.2 litre diesel with 620 cold crank amps according to the electrical information in the service manual. Coming back to my original question, regardless of what Noco says, do I actually NEED more than the GB40 to reliably start my vehicle with a flat battery? I’m based in France, and the units are more expensive here than in the US, with the 1500 amp GB50 ($230) being almost double the price of the 1000 amp GB40 ($130), and the 2000 amp GB70 ($260) being only marginally more than the GB50. I’m all for spending money on good quality products, but I would much rather put the extra $130 in the tank for travel.

But what you missed is the GB70 and the GB150 can be used to power things like your fridge etc or to power the ECU in your vehicle should you need to change or charge the Battery The GB150 will start engines over 10L+ Gas or Diesel, I managed to run my small fridge from the GB150 for 4 hours and I have powered my ECU for over 9 hours and it was still reading over 75% full, I own the GB40 and I gave the GB70 to my Brother and I use the GB150 on a weekly bases, personally I would not consider the smaller models because the larger models can be used as a backup power source for many things as I have already said.

It's a bit like the ARB Compressors you buy a 40/50K truck and run 300 /500 dollar Tyres and then buy a 100 dollar compressor where as I bought the 2 Portable versions from ARB, My point is why cut corners on the things that really matter when you are in a bind, ??

Noted. So what I hear you saying is, the GB40 will do the job of restarting my truck, but a higher amperage unit will give me considerably more flexibility when I need it. Given that, yes, I think it does make sense to buy a more powerful unit. Appreciate you reiterating your earlier point. I definitely don’t want to find myself needing more power and not having it.

If your need for jumpstarting redundancy is mission critical

do not use these units as regular powerpaks to power other devices except in emergencies.

Keep it fully charged in the glovebox, tested and topped up regularly, and replace every few years at most.

Then use the "retired" ones for whatever you like of course.

Murphy's Law, alone in the wilderness far from help. . .

Of course having two and swapping them out ensuring one is always Full

could be done, but IMO more secure to have well planned House bank capacity for non-essential "auxiliary" devices kept totally separate from engine/primary/essential loads.

None of which implies you should not get a bigger unit than what you strictly need now, for pure safety reasons

Engine misbehaving, spark / fuel issues, out of tune, might need many more seconds of cranking than when in great shape.

Powerpak capacity declines over time, don't start out with "barely enough"

etc etc
