Next Gen Ranger Raptor battery issue! Please help

[RaptorChe]

Hi. I have a 23 Next Gen Ranger Raptor and least week the battery went flat. I jump started the car and used it for the day. (All the sensors were going off al day) next day, battery flat again. So I went out and spent close to $600 on a brand new battery. Drove it for the evening, next morning, new battery dead… any help or thoughts?? I’m going crazy

Well, there are two possible scenarios.
1. Your alternator is not charging correctly (low or high voltage) - measure the voltage on the battery with engine running= should be above 13.5 VDC and increasing with the engine revolutions.
2. Could be current leakage - with the car of, disconnect the battery positive terminal and connect an amperemeter in series to measure the current - should be no more than 50mA.
If it is more you need to start remove fuses to find out from where the leakage is coming from.

Hope that helps

It isn’t the alternator if he drove it the rest of the day after the jump.

Thanks heaps for all your advice. Ended up taking it to an auto electrician as Ford couldn’t fit it in for 5weeks!! Found out it was the factory amplifier… drawing a constant 15amps at all times. Removed the fuse… no problems! Except now I have no music!! Anyways. Now I know it’s not a MAJOR issue, waiting for Ford to “fit it in “ and fix through warranty….

I’m having g the exact same problems with my battery! Really giving me the shits sometimes it’s fine. Then I lose windscreen wipers or windows down open or other faults on the Ute. I charge it and it’s fine for a hour or too. I don’t want to have to spend heaps on it as the minute I take to ford it’s gonna cost a bomb as they will say not under warranty as it’s a battery related problem. any ideas much appreciated
Cheers.

Encountered OE batt failure ~4 wks after delivery in Feb `25; totally unsat!
Replacement covered by warranty, but what if off-road, at remote location!?!

Decided to hedge AGM batt risk with a proven more robust, reliable solution, similar to what I run in my ///M cars... lithium batts. Offers a plethora of benefits and peace of mind over ANY AGM spec.
Cost/benefit over ~5yrs compared to a typical ~3yr AGM lifespan/replacement...a no brainer!

My choice = 'Antigravity Battery'...here's the direct replacement for a RR along with amp hour options.

wow, when you first see the price, its kind of shocking. than it sinks in how much regular batteries cost and you get over it a bit

Yup, higher initial cost. Lifecycle cost and reliability make the "business case". My oldest AG is +5yrs old still goin' strong, never any issues.

With that, functionality and capability to monitor/view batt status, key specs, history, run various diagnostics and more.
Coolest feature, "Built-in Jump Starting" so no need to carry cables or other batt starter if something goes sideways away from home.

I was a massive fan of Northstar batteries.

The team developed the Odyssey battery, and eventually stepped out from Enersys to do their own thing. You could beat the snot out of them. They soaked up a charge like the best flooded cells, and held their own through hell.

Then, Enersys bought them out. I'm not sure if there's a current massive difference between an Odyssey and a Northstar-branded unit but, historically, Odyssey batteries tend to be very picky about charging, and for some time suggested sending them back for refreshes periodically.

That made them nice for around town and general overland use, but inappropriate for vehicle-dependent expeditions. Northstars went the distance and could be maintained anywhere.

The only step up is lithium, but historically they haven't been super for extremely demanding winching or long-term ancillary use.
