Yup, Mazda Q85 is special.
-Recognized Substitutes:
Motolite 1SMF/NS50ZZL/D23L
AC DELCO: SQ85D23LEFB
-Cost: Php15-25ish K
-Life is dependent on usage.
-Reasons why a specific battery for i-stop system is necessary
When a vehicle equipped with i-stop system stops at a red light, engine is stopped for fuel
economy improvement. When the vehicle starts to drive again, the engine restarts. So, battery discharging and charging are repeated in a short period of time.
Also, during i-stop operation, as electric power for air conditioning and audio systems etc. is supplied from the battery only, discharging occurs more than on vehicles without i-stop
system.
If a battery other than the specifically designed for i-stop is used instead, its lifecycle may be reduced or it may disable i-stop function.
-Lowdown on differences between Q85 & regular batt:
It has improved durability/charging acceptability. In order to achieve these performances, it
has the following features.
① More durability
(1) With the use of narrow grid, holding capacity of active material is raised to prevent active material from becoming softened and dropping.
(2) Charging ability is improved by reducing sulfation due to discharging.
※Sulfation :At this condition, battery cannot be reduced to lead and sulfuric acid even after charging because lead sulfate, which is generated during battery discharging, causes coarsening in the recrystallization process.
Recrystallization progresses gradually. So, by keeping the discharging condition (with more lead sulfate included) for a long time, sulfation occurs, which lowers battery capacity or charging ability.
② More charging ability
(1) Additive included in lead of battery plate
is optimized to increase charging
performance.
(2) Reaction area is increased by having
more battery plates to improve charging
performance.
On the other hand, though charging acceptability has increased with more battery plates, dendrite short is more likely to occur due to smaller gap between battery plates!
※Dendrite short: If sulfuric acid concentration in the electrolyte solution decreases battery is exhaustively discharged. At that time, lead ion dissolves from lead sulfate. If
the battery is charged under such condition, lead ion grows and becomes like a shape of a needle on the (-) battery plate surface, which is called dendrite.
Why Shell Fuel Save? Technically, SkyActiv is not your regular direct injection engine. This is a hi-comp engine that runs on regular unleaded w/o the dreaded knock. To ensure smooth long running service, efficiency & yojin warranty retention, it's ideal to stick w/ what Mazda has endorsed. After all, going above the required octane won't add gains nor benefits, only cost.
Skeptics will always have their conspiracy theories about this....but to be safe & to make sure of yojin warranty, I'd rather submit & stay w/ the recommended.
