Is this a correct/good replacement for the OEM batteries?

[AH64ID]

Got a NOCO 5 and repurposed my old NOCO 2. But I was not confident that the 5 was going to perform too much magic on my abused 4+ year old OEM batteries.

The OEM batteries tested marginally, one a little worse than the other, but not dead by any means. But when I thought about how much they were down from an already marginal starting point when new, I decided to put in two new Walmart EverStart Maxx batteries. They are starting from a place the OEMs could only dream of so a big improvement and with the NOCO 5 to take care of them, hopefully will have a long life. At least the locks, etc. are behaving now.

Probably not a bad idea to start fresh.

Good call if they are testing on the lower end of good you are on borrowed time in my experience….I may be replacing mine soon I have not tested them yet but I have noticed slightly slower cranking and a the other day I was having my HVAC and radio kick out after operating the plow occasionally which its never done before. I will have to charge them up this weekend and test them

or put a charger on the truck to keep it 12v+.

Be careful with this. Some battery chargers will not regulate 12vdc very well if there isn't a battery load. Some of the smart chargers also use a pulsing output that can wreak havoc on a vehicles electrical system.

One of those 12v jumper packs would be MUCH safer if you're worried about losing settings. If some things aren't working right I wouldn't keep 12v on it, let everything reset.

I have not heard of this. The NOCO Genius chargers have a green pulsing light once the battery is fully charged. NOCO says this mode is "Maintenance - Slow Pulsing Green - After the battery is fully charged, the charger will continue to provide ongoing maintenance and optimization until disconnected".
Not sure if only the light is pulsing or what. Probably the dangerous pulse charge output you refer to is unrelated to the NOCO pulsing light? In any case I have never heard that the NOCO Genius chargers have a reputation for damaging electrical systems.

Any of the experts here have an opinion on this?

NOCO will not damage your system at all.

NOCO’s stop charging when the battery is 100% and only start charging again when the battery SOC drops. That’s what the pulling green light is indicating.

I did not mention any brand, only noted some chargers can cause issues. First came across this in 2012 with the fuel injected KTM 450/500 motorcycles. Some chargers would cause the ECM to trigger the fuel pump relay, specifically a certain model of Battery Tender.

It caused some ECMs to fail or the fuel pump relay if one didn't notice it was happening and the bike sat in the garage for weeks doing this with tens of thousands of cycles.

It would be wise to stay away from square wave output chargers with all the electronics now. NOCO doesn't do this, I've checked them with a scope.
