Im an OE user - however - to the extent it keeps the vehicle original/ meaning ...if I was to sell it ..it dosent appear any different than the day it came off the showroom floor - like a time capsule - If you have the tools, time and kniwledge to tweak your ride to another level - -my hats off to ya - Ive never been a resto-mod person - but like seeing people who know the craft do cool things that actually improve the vehicle - usually performance - Tires - I use the correct size and best temp/ treadwear / load for my use - , battery is correct spec Interstate - or respectable mfgr line - but not a " Mazda " parts battery - pads , engine parts , , my TCM is OE ..yes $500 but hey - I recently hit the mother lode and found an EXACT copy of my 2010 MAZDA 3 2.5 Gt in silver ....in a pick and PULL JUNKYARD ! I pulled the side mirrors with integrated turn signals , bushings , clips ...its was Xmas day - and still have window motors , water pump etc ...but the color match was a big big bonus ! Dont ever stop looking in salvage yards for your exact car ...eventually the day will come ! OE paradise ! -

Not exactly sure whom you are referring. But based on past responses on this forum from you ...
If not so much the battery as the upkeep on the sales lot prior the sale of new vehicle. You would be surprised how many new vehicles get their batteries drained and recharged by way many times a fast charge starts and let the engine idle for 30-45 minutes early in the morning before the dealership opens. This reduces the effective and reliability life of most any battery.
Ya unfortunately on forums the higher percentage of members post less than the most accurate information about generally anything related to normal operating and failing of parts on any vehicle. So, the inaccurate disruption makes it very difficult to actually hep members when they see multiple posting of the same inaccurate information descriptions. Or they try to include operation in an abstract as if that is correct information. Example all modern vehicles from about 2016 will have a constant draw of power to operate onboard electronic and can reduce the battery voltage lower than the minimum voltage to operate them. This would be accurate, but the missing part is once the voltage drops below the required power/voltage or amp to run the component it will no longer reduce the battery voltage or amps. This means a "dead batter" will still have some volts or amps but not enough to turn on a single light bulb. It also means that it will take more effort to bring the battery back to life.
Case in point and ongoing event.... Airport every day and several hundred to the thousand need a jump to get their returning passengers picking up thir vehicles in the parking lots both long- and short-term parking. And it is more predominate with newer vehicles. However seldom if ever do the batteries need to be changed out because of discharging below while being parked for a length of time. The batteries in ALL cases that need to be replaced because of a discharge as talked about in this thread and often the case is because the battery itself was already on the verge of failing a basic load test and on its way out needing to be replaced in a short time regardless of the discharge event!
I think you mentioned something in one of your responses?? lol

- another laugher was a local dealer near me ( where I never go ) that pumps the tires to 50psi + on all tires ....get this ...to avoid " flat spots on the tires " -so they sit and are demod with that psi-and delivered often with 50psi - anyone ever check the tire psi after buying a new car ? I just bought 2 in the last 2 years ...all tires were off by over 5 psi ( a cold tire check with my analogue gauge before and after home and tires fully cooled )
Im sorry to say both Mazdas -
the stories I could tell about dealers ( not specifically Mazda ) that have some damage while its between mrgr drop off and sale ..that NEVER gets logged into vehicle history ...is staggering . Ive seen it all - or close .....a guy reversed the jumper cables on a very expensive german car - snap - solenoid and smoke from the fuse box - 8 random fuses and God knows what else - never logged - sold with no doubt many locations of wire harness damage only to be discovered much later - After working at many dealers - I learned one thing if nothing else - order a vehicle and arrive the day B4 its PDI'd and take delivery before the number of lunatics that drive it increases - or find a vehicle thats in a storage area - pre-PDI , with shipping tape and interior plastic still itact from the factory - and of course 2-4 miles on it ...NEVER dealer traded -
This is NOT directed at MAZDA dealers but from my experiences at a panoply of brands - Many may disagree - but more can happen to a new car at the dealer than at any other stage prior to delivery or during responsible ownership .
