Howdy! Here is the Memory Saver that works for the Range Rover www.amazon.com/dp/B07KCN69LJ?linkCode=ssc&tag=onamzjasonlew-20&creativeASIN=B07KCN69LJ&asc_item-id=amzn1.ideas.1XF6P87AOM0Z9&ref_=aip_sf_list_spv_ons_mixed_d_asin
I'm really glad you're still doing high quality videos Jason. I have followed you for some time and really enjoy each and every post you have created. Hope we can cross paths one day so I can buy you a cold one. Stay Strong!
When my stock battery failed in my JKU, I put a yellow top in it, and have been very happy with it. I feel a lot better running a winch off of it than that OE battery. I bet that 12V feed was on the wrong side of a diode or something, so the ECU and such was reset.
That's kind of what I experienced with the Rover on those cold mornings... running all of the heater elements is a huge draw and the deep cycle capability of the old battery was just depleted. I figured out that on the Rover, all of the power outlets are on a switched relay that closes soon as the battery terminals are removed. The smart way to do this same maneuver would be to buy the same 9V battery setup with an obdII port adapter since that is hot all the time but that was $25 and more than I wanted to spend extra at the moment. All of this stuff adds up so dang fast.
@@AutoEdits Yeah, especially when you don't gain much for that $25. If you run a shop that does this all the time, it would totally make sense. But not for a one and done.
I've replaced several of the DH7 yellow top batteries in my 2022 concrete saw. The saw was delivered 10-9-2022. One of them only lasted 5 working days. A few lasted barely over a week. 5 or 6 lasted under a month. I think the size of the plates has a harmonic resonance that destroys itself in that application. I installed a smaller group 35 spiral cell yellow top battery in October and haven't had a problem with all-out battery failure since. I did need a jump start back in February but since it's been fine. I carried a spare because it was such a problem.
I have 2 Optima DH7s. One in my Gladiator and one on a battery maintainer. My motorized steps always draw a small amount of power and on top of having a modern vehicle with computers and modules up the wazoo, the battery will be depleted no mater how often I drive. Once my Glad starts acting up and I notice before start up the voltage is below 12v, I go ahead and swap Optimas.
Hey Jason. Just thought I'd share something about that rear power outlet in your Jeep. You can make it an always hot or switchable by changing the location of the fuse.
Battery install... Boring. Battery install that doesn't go as planned.... Now I'm watching to the end of the video. Got my Optima Yellow top 7 years ago after watching one of your videos. Its in vehicle number 2, for reference my work van (drive it everyday) is going on parts store brand battery #3.
You had battery tender cables on the terminals. Could you have just plugged the tender back in during the swap? Probably not since the tenders usually need to detect the battery voltage, right?
Good observation, yes the charger shuts off when there's no battery and I could've just connected straight to my spare battery but just wanted to try this little gizmo. I was kind of impressed it worked absolutely perfect on the Jeep.
Good suggestion, although I opened the door multiple times on the Jeep and it worked fine. The problem with the Rover is all of those outlets are on a switched relay and soon as battery power is lost, that switch closes. I could've used an OBDII 9V adapter instead but that was $25 bucks and more than I wanted to spend as a gag for this video. If the stakes were higher due to the stereo locking me out or something, I would've invested in the right tool!
Nice video. Interesting with the 9v battery maintainer not working on the Range Rover. Most likely due to the integral electrical system and all the control modules. I have a more specialized version of that tool. It gets plugged into the OBD2 port and 110 outlet. I've used it several times...and works perfectly, even on Euro vehicles with complex CAN systems. Speaking of, do you need to program your NEW battery to the BMS (battery management system)?? Thanks.
Thanks for the info! Yes, I should've spent the extra $10 on the OBDII memory saver instead of the 12v outlet!!! I did use my iCarsoft and set the battery to new. Is that what you mean?
