You can always ask Whistl3r to have an item shipped via Grab. Sadly a battery is on the heavy side.

GAT Performance is within BF Homes. They specialize on aftermarket service of Subaru vehicles. They sell Energizer car batteries.

I want to buy that charger unfortunately i live in a condo and we dont have any power outlet in the parking area. Thanks for the reply.

I'll check this one out Sir Egan. By the way compared to yuasa, is the energizer reliable? Thanks

I haven’t tried Energizer. We use only Amaron on the cars at home and we don’t have a Mazda. I heard na marami na users ng Amaron for Mazda vehicles. Yung Amaron ng FXT ko more than 3 years na.

Had I iStop, I'd go EFB or AGM of any brand over any Regular Flooded Batt out there....esp if the car is still under warranty. The iStop/iEloop systems aren't cheap.

Spec-wise, some of the Energizer SLIs(Starting/Lighting/Ignition) Regular Flooded Lead Acid batts have better specs than Motolite Excel, and even Amaron Pro. Their EFBs, at current prices, are a bargain. Energizer AGMs are priced really well, even cheaper than some EFBs by others.

Thanks for the replies. Btw any idea kung may negative effect ba sa car pag pinatanggal ung i-stop feature totally? Saw this sa isang store na specialized for mazda vehicles here in the metro.

here's my observations on mazda i-stop feature..

on the battery - there is nothing "special" about EFB except that it is just an "enhanced" version of your regular flooded batteries!.. its like buying a low end motolite vs the top of the line. one thing good about EFB is they last longer compared to your regular flooded batteries. now EFB will be good if you activate i-stop because the car will rely heavily on the battery when i-stop feature is activated.

on charging - there's nothing special with mazda charging system.. its a regular alternator with IC controller and it will charge any regular 12V car battery.. one thing special is that the alternator will also charge a capacitor to store energy once the system detects the car is using engine brake

observations on the i-stop

i-stop feature will activate within a few minutes... almost immediately after the car starts rolling.. hence the need for more robust battery since your battery can be used by the car's electrical system almost immediately after starting.. and the battery without getting enough charge after starting, this is a hard task for a regular battery..

mazda's battery sensor can sometimes be too sensitive.. EFB batteries can maintain 12v better than regular battery.. when the system sensed that the battery voltage drops too low for its set range after starting, it may trigger an i-stop error... mazda efb batteries is almost as big as a 3sm battery used in most diesel engines!

workaround i-stop

turn i-stop off with the dedicated switch.

it will not activate if the driver is not wearing seatbelt

on full stop, turn the wheel slightly on either left or right

press lightly on the brakes (but i do not recommend this)

set your AC temp to the lowest (18). do not worry as your AC system temp is controlled internally and does not depend on the "temp setting" in your dash..

the system has its own temp sensor inside the evaporator and does not depend on the temp setting on the dial.. not like with most toyota vehicles where the temp is controlled by the cyclic action of the compressor... with mazda, even if you set the temp to "24" deg or "18" deg the compressor will cycle on its own.. per observation, once the system reached its internal temp setting, the compressor will cycle on/off for around 10 to 20 secs..

i think mazda intentionally set the temp a little higher than usual as i notice the compressor to cycle off more compared to my previous car.. usually the evaporator temp is set at around -5 deg to achieve a 9 deg air temp at the vent

so even if you set the temp to "18" the compressor will not cycle longer to reach "18" and if your set the fan to "auto" it will just increase fan speed to reach the 18 deg but it will not cycle the compressor longer.

EFBs don't just last longer. They also charge faster and feature more cyclic durability in deeper discharge scenarios like start/stop. I have an EFB in my car without any start/stop tech because I hardly use it now and the price difference vs standard is only around 800 pesos. When I use it during short trips (¬10km) I don't worry that it'll get discharged too much anymore. I think it is worth it to upgrade with the minimal additional cost specially with today's cars which have a lot more electronic accessories. Audiophiles even go the extra mile and upgrade to an AGM. But those are a lot more expensive.

Most luxury cars have AGMs as OEM as they are loaded with a lot more electronics vs mainstream brands.

^+1, but not all EFBs are equal. Motolite's was junk. Thanks for chiming in, good sir. Hope you can help supply those in need of EFBs/AGMs here.[emoji120]

No prob bro. Already referred Mr Kamote to someone I know in the area.

Apologies if I don't post much as I usually shy away from self serving topics.

agree sir.. if there are EFB options with almost the same price range with regular batt.. i will opt for EFB due to their durability.. but mazda owners with no immediate access to EFB need not to worry on using regular batt.. i think some owners worry that it may affect their charging system..

what i would like to know is how those LiFeP04 "smart" batteries perform with regular cars and cars with i-stop system..
