That's the model is used to bring my 2019 Niro PHEV battery back to life 3 years ago when it completely discharged. I have no problems since.

Our 2019 Niro PHEV had its battery discharge almost completely a couple of years ago. The BatteryMinder trickle charger did a very good job of bringing it back to life. I've had no other problems with the battery since then. I put the trickle charger on ours quarterly - it does a very good job.

I have a Noco Portable power unit I carry with us if we ever need it. Have trained the other drivers in the family on how to use it if necessary.

I am going to take a different path on our battery and keep using the original battery forever if I can. The Niro PHEV doesn't demand a lot of the battery and I am interested in how long it will last.

The BatteryMinder is a smart charger with a desulfate feature. I also use it on our other vehicle a Hyundai Santa SEL quarterly. I am interested in how long these batteries will last with the maintenance charges quarterly. With a Car Battery now approaching $200 I look forward to saving the combined $400 it would cost to replace them.

The Noco Battery Boster makes it a non-event if the batteries do fail and hopefully, I can spend the $400 on something else.

Out of curiosity I had the NIRO battery tested recently by a parts store Battery Load Tester = good condition - no problems.

I will not hesitate to replace the batteries if they fail or indicate they are becoming weak.

Look at this website and read the advertising about why the BatteryMinder and devices like that can extend your battery life

BatteryMINDer 1500 | 12 Volt Maintenance Charger Desulfator (batteryminders.com)
(Scroll down the website to see all the information)

Here is just a snapshot of some of the information there.

"Quadruple Your Battery's Life
The SmarTECHnology™ Plug 'n Run 1.5 Amp battery charger/maintainer system features a full-time automatic pulse desulfator that can help extend a battery's life up to 4 times its normal life when compared to new batteries that are not being properly charged/maintained over their lifetime. Just plug it in and the BatteryMINDer® takes care of the rest.
The Right Charge Every Time
An automatic high-low temperature compensator is installed in the BatteryMINDer® to ensure that batteries will never be overcharged or undercharged, regardless of the operating temperature. This ambient temperature sensor is installed for a -4°F (-20°C) to 122°F (50°C)."

I couldn't begin to explain better than these people or their product cut sheet.

We are talking about the 12v lead acid battery in a NIRO PHEV - it has nothing to do with charging a lithium battery.

The HEV NIRO has a 12v lithium battery but we aren't talking about that one.

I might be a good experiment for you. When I hook up my BatteryMinder 1500 to my 2019 PHEV NIRO EX I never disconnect the battery. I use the chassis ground and the + terminal in the fuse box in the front engine compartment. I have been doing this for 2 years every 4 months with no bad results yet.

The one exception was when my 12v battery completely discharged in 2019 I did remove it from the vehicle before charging it. It voltage was 5.1 volts before the BatteryMinder bought it back to life. It was the original battery, and it is still working fine after it was bought back to life.

Techy is right there are no gotchas when the 12v battery is disconnected - at least on a 2019 PHEV NIRO.

I was pleasantly surprised back in 2019 when I had to remove my completely discharged 12v battery for 2 days for our BatteryMinder to bring it back to life. Put it back in the car - the car came to life and my settings were fine after 2 days with no 12v battery - I don't even think I had to redo my radio presets.

After this happened, I did buy a Noco Battery Booster so that if my battery died, I would be able to start the car immediately - even with a dead battery. The Noco Battery Boosters have a setting so that it will start the car even with a completely dead battery.

Another quick note to this thread- one of the post could confuse individuals that the NIRO EV or PHEV use an OEM AGM battery. Unless KIA changed this year NIRO EV and PHEV are using Closed Maintenance Free Lead Acid batteries.

Replacement AGM batteries will work if an induvial wants to go that way
