Battery Tesla or YUASA

My 12v battery died last winter and I decided to replace it with a Yuasa Silver battery after hearing people having problems with their 12v battery. It has a 5 year guarantee which gives a bit of peace of mind.

Yuasa are always good, but I've been a big fan of "Big Crank" / [Batterymart.com](http://Batterymart.com) batteries on most of my bikes.

Yuasa is absolutely the way to go

For the new Niro EV get a 027 battery from a third party. I got a Yuasa 027 65Ah for £90 from Halfords UK.

Tesla on nmc battery drops around 10% after 8 or 10 years (can't remember exactly) from what I read. But lfp battery is inherently able to have longer life span and charge cycles. On top of inherently having ability to be safer / less explodey.

For context, I have a first generation Tesla Model S - 2014. It has 215,000-ish miles on it. The battery capacity has gone down by about 10-12%. It still runs and drives like a dream. It's on the original battery.

I've never had any reason to regret my decision in the past 15 months of ownership, and I absolutely love driving it.

My 2019 M3 with 50K miles says 288 miles today (310 original) but it has been far lower at times (255 miles) and bounces around.

battery life is astonishingly unpredictable. I drove 20 miles, but lost ~35 miles of range. Not driving crazy, either. Everything else is decent, but can't help but feel like it's a time bomb.

2019 model 3 SR with 10% loss based on full charge at 52k miles.
