I once had a calcium battery in my 240z and 300zxtt and they worked for over 10 years! (I kept them under a small battery trickle charger when not used.)

Now i have ordinary lead battery's and one is (2018) also already giving up.. ( one time it got very low as the car has a alarmsystem and the charger wasn't on it at that moment, so i guess i was the culprit..oeps..)

I'm thinking of getting these calcium battery's again, they stay better when used only few times a year..  And the price is not much more if any..

I remember the days when batteries came with a 10 year warranty

Update: I picked up Costco's Interstate battery (1624505 this one) for $120 and it works great.
