The battery that refuses to die
Good morning everyone. So here in an interesting story. My cranking voltage on the 4Runner was a bit low, so I checked out to battery to find out that it was installed in 2019 (while the car was in Japan). That means this battery lasted for a total of 7 years (4 in Japan and 3 in the UAE). And it still functions (just the cranking voltage is a bit weak). But Im so impressed with this brand. Also I checked; it's not available in UAE. Anyone here from Japan give me an insight on why this brand is this good?
Also why do batteries available here in the UAE die the moment warranty expires? like there is some timer?
