10 Years of battery usage

 My Yaris is now 10 years old: it's time to have a look at its battery:


It's still looking good, with delta between battery blocks under 0.1V most of the time, just a little worse than the 8th year check.

Car usage is mostly urban, so plenty of EV battery depletions, and forced charges, because of slow moving traffic. Open air parking at night also.

On a side note, the 12V battery is still the original one.
I've never had a car with a service battery lasting more than 5 years: probably the periodic CTEK treatment had some benefical effect on that.
