The Q85 batt is likely an AGM than an Enhanced Flooded Batt...Here's more info from autobatteries.com:
"AGM batteries have been adopted by the automotive industry for their proven performance in high-end and advanced fuel-efficient vehicles with large power demands.
AGM batteries are extremely resistant to vibration, and are totally sealed, virtually spill-proof and maintenance-free. AGM offers better cycling performance, minimal gassing and acid leakage when compared with conventional lead-acid batteries.
The end result of all of the features of AGM technology is superior life performance while operating at a lower state of charge.
AGM APPLICATIONS
AGM batteries are a great premium choice for high-end and advanced fuel-efficient vehicles with large power demands and for people who seek greater reliability and longer life in auto batteries. Electronic features such as DVD players, GPS, heated seats and audio systems all add to the demands on a battery.
AGM batteries are also the preferred solution for start-stop vehicle technology, which rapidly gained popularity in Europe and entered the U.S. market in model-year 2013 vehicles.
Start-stop vehicle technology automatically shuts off the engine when your vehicle stops, such as at a traffic light or in stop-and-go traffic, and restarts it quickly and quietly when the clutch is engaged or the brake pedal is released. When the engine is off, the battery is the sole source of power to all the car’s electrical devices, such as air conditioning, the radio and the navigation system. And, in advanced start-stop systems with features like regenerative braking or passive boost, the battery is stressed even more.
In order to power electrical loads during engine-off periods and to support a high number of starts per trip, these vehicles need a battery that is more robust than the typical lead-acid battery. With superior cycling capability, charge acceptance and the ability to operate at a low state of charge, AGM is the technology of choice.
AGM CONSTRUCTION
In AGM batteries, the positive and negative plates are separated by an absorbent glass mat that absorbs and holds the battery’s acid and prevents it from flowing freely inside the battery. The plates are tightly compressed into each cell and held under pressure in the plastic case. The internal compression limits the shedding of plate material caused by cycling and allows for significantly longer life. The element compression also lowers internal resistance and maximizes pulse power output. A rigid container maintains the necessary compression throughout the battery’s life.
The basic design also includes relief venting to release pressure from minor gassing that occurs during charging. The valves open at low pressure and close automatically to prevent air from leaking into the battery."
AGM BENEFITS:
-Longer life and dependability
-Handles high electrical loads
-Quickly recharges and extends cycle life
-Ideal for start-stop applications
-Vibration tolerance
-Non-spillable and maintenance-free
-Greater mounting flexibility
AGM DISADVANTAGES:
-Higher initial investment
Here's a link to Century's Q85(Aussie) w/ only an 18mo warranty:

I really hope Motolite has the technology to do AGMs.
Guys,
Our garage has roof but has high ceiling and open to sides, so if there is rain nababasa pa rin si m3 ko, so i am planning to buy a car cover any recommendations?
Yung hindi sana didikit sa kotse pag mainit.
To 2.0 owners. Anyone here tried replacing their battery? How long did it took you before finally replacing it? This is one of my dilemma as i have to travel 500 kms just to replace it in the nearest casa 😣

[QUOTE=travajante;2666183]The key to lengthening the pricey 2.0 Q85 battery life is A PIECE OF PAPER....LITERALLY! Haha
Lol so ill just have to turn it off permanently then. Is this what the other guys do in fb group? I mean do they not use the istop function

[QUOTE=chiezee;2666195]The paper is the lazy man's way to turn it off permanently,otherwise, you'd have to push that switch on every drive.
Mine is the hobo 1.5, so that's some 2nd hand info. Try & observe...I'm not sure if there are risks....but benefits, definitely.![]()
The battery is made for istop, so its more heavy duty than regular batteries. I would not worry about it for at least 2 years. My logic is that the oem battery can't simply be inferior to motolites, haha. It's my first car with start stop function too, so we're all initial testers here.
Though batteries in general, the main killer is actually heat and if the manufacturer actually designed for it to last only just after warranty *cough motolite *cough
Bmw or benz batteries made by varta can last 4 to 6 years if your car is garaged (talking about the standard types, not even agm type), parked under the sun the same batteries last for only 2 to 3.
I know mazda ph and motolite were in talks to develop replacement cheaper batteries for our 3s, don't know if this pushed thru.
Before your batteries die, you will have some signs like its difficult to start, etc. so replace them soon as you notice it, but i know your worries, been a lot of times also that i am far home when battery died, or worse battery was not in stock when mine died. No choice but to order and wait and install myself or have your car towed. I prefer the former.
Speaking of istop, it does not function if you just step on the brake pedal lightly while stopped with gear on drive. Try it, press the brake pedal until you stop and once about to stop, adjust your application, there's a thin difference but you will get a hang of it, even if istop is ready it wont engage.
Unfortunately, Motolite is the supplier of the Q85 deep cycle replacement locally. Like you, balong sir, I'm no fan. I've been repeatedly burnt over the years. That brand really slid when they siphoned resources from batts into KFCs & Mr.DONUTs...
Here are the Q85 equivalents i've dug for y'all w/ 2.0s to check & compare....
-Motolite 1SMF/NS50ZZL/D23L
-AC DELCO: SQ85D23LEFB
-OPTIMA YELLOW 8012021 FFP Group34
I'm not sure if Delco is any better, but that's what the Aussies get. Optima is good, tho, but they're sized differently...the fit could be a challenge.
Aside from Varta, BMW also used Exide, at least for MINIs....a buddy's still has 1 from 2006 working to this day.
The genius difference? The battery is in the trunk....better batt environment, lower temps, better weight distribution....👍
Mazda being an obvious believer in Bimmer drive dynamics should've taken cue. The consumer benefits far outweigh the manufacturer's cost...just a longer harness, a well rust-proofed & vented trunk batt compartment aren't difficult requirements. Perhaps in the facelift????
Unless the Q85 & equivalents go well beyond 2years, realize the math.....present local Q85 batt cost will never be recovered by iStop gas savings based on current pump prices & real data we've gathered from 2.0 buddies in local drive conditions....not to mention the local traffic effect on efficiency....&, the longevity of the capacitor. That will even be costlier once yojin leaves.....all these, the long term intention & more, pointed me to my hobo.
Simply put, I wanted SkyActiv not the iStop.![]()
So natuloy pala yun mazda x motolite collab. Im sure mazda ph would at least let motolite match its spec for the replacements, given how many cx5 and mazda 3 with istops are out there, especially if they sell it as oem replacements from casas. Otherwise they will have a big problem. I hope we can still order the oem battery installed from japan factory, if customer wants to pay for it. Or parallel smugglers will have good business 2 or 3 years from now.
Re bmws and benz, mine all came with vartas, amazing your buddy's lasted 9 years, never heard that before. From personal experience 6 years is my max. Oh, not all bmws have batteries in the trunk, fyi. The battery i was talking about lasting 4 to 6 years is up front in the engine bay but garaged, while the 2 to 3 years was in the trunk, parked outside. And bmw trunk battery compartment (at least on mine) aren't vented, in fact they are semi sealed as they are covered by trunk mat lined with carpet. Just that the battery have a tube going outside the vehicle to release whatever it needs releasing that can be bad for humans.
Totally agree, balong sir.The japanese Q85 will probably be 10k-ish more upon reaching our shores. If they'd last 4-6, then iStop would be worthy here.
Oh, true, not all bimmer batts are trunk mounted. My reference there was to my bud's R53. DIN batts come w/ holes for tube venting.Mazda should look into trunk mounting as it'll help.
My batts are kept healthy w/ the aid of a pacemaker, Deltran Battery Tender. They help keep all those gremlins off, esp those that haunt euro BCMs & ECUs.![]()
Just wondering can you use smart charger for this type of batteries?
