Yuasa builds a damn fine battery. The one in my C14 is still hanging in there after 6 years.
Yuasa is the good stuff. It's all I'll use in my bikes.
My battery was the [factory one from 2007], changed it in 2023. Couldn't find a replacement Varta back then and had to choose fast, so I picked Yuasa (Japanese brand) and it's working good till now.
I bought a shorter mobility scooter battery with same chemistry as the original, YUASA REC36-12, however the polarity was reversed. I extended the negative pole and installed it without an issue and car came back to normal.
Nice hack. I have a Yuasa that will be 13 years old this year and still going.
I have a yuasa ybx 3000 recharging battery for Mazda 6 2011. I've had it three years with no problems since recently.
You can get an Deka AUX18L from batterymart.com for $159 shipped to your door. Deka is the OE manufacturer of the BMW battery for the i3. My original battery lasted 7 years, it’s a no-brainer.
For the last couple years my riding mower has been starting off of the Yuasa battery that I had taken out of my Valkyrie. I took it out because it was 10 years old and I thought I might be pushing my luck with it. I credit using a tender to give me 12+ years on my bike battery plus it\u2019s a quality battery.
Quando vedo che fa fatica la ricarico, se lo rif\u00e0 in tempi brevi la cambio. La Yuasa che avevo su \u00e8 morta lo scorso anno dopo 6 anni e 60mila km.
Unfortunately have to disagree about Yuasa, This 2018 battery is not the same as what you will get as a replacement from Yuasa today. I think they moved manufacturing from Taiwan and the quality has fell. My last two DRZ400 batteries were Yuasa and they didnt last 2 years. Even with tender on for the few months I didnt ride the bike.
