TIL - Today I Learned...

[Miles_on]

The stock battery of my 2024 Santa Fe died after just 18 months. I suspected that perhaps it was an old stock from Korea, but more likely ang daming accessories na ng mga bagong kotse ngayon, hundreds of sensors being monitored by the ECU, bluetooth, wifi, GPS, auto headlights, DRLs, wireless/wired chargers, cameras, etc. My friend's new-gen Corolla also had the same issue with batteries.

The stock NS60 battery that came with my unit was a different type of Amaron unavailable locally (direct from India), but was super tough. It was 5 years old and still cranking strong with no problems- puro short drives (10km or less) pa halos ang use so bugbog siya (it doesn't fully charge). The only reason I decided to replace it a few days ago was because I detected some signs of swelling na sa casing. Medyo nanghihinayang pa nga ako palitan kasi wala kang mahanap niyan dito and I feel it would have lasted me 1-2 more years. The most common replacement available locally lang was an Amaron Flo which I got cheap (factory price) because good friend ko yung battery dealer.

It was 5 years old na in my service, but who knows how old it really is, because the unit could have been in the car dealer's warehouse for quite some time before I bought the vehicle.

To be fair, the NS60 is a tiny 45Ah battery with 360CCA and an RC of about 75 minutes... when it was new. But it also depends on the load.

Yep. Tiny is right, as the NS40 & NS60 is what they usually put in small Japanese cars. Malaki yung battery tray in the engine bay though, so I think I can use an upsize battery din if I make some slight modifications, pero tinatamad na ako mag handyman.

The 12.2V you read immediately after turning off the radio will rebound back to a higher resting voltage after about 30-60 minutes.

Oh. Hindi ko naisip yun ah. Perhaps nga, but I wouldn't chance it pa rin!
