If you've got 15 years out of it you did very well...I thought I did well with 9 years on the last one...Time will tell if it holds or not... Now it's a waiting game to see the results...If the vehicle's charging system is in good working order it should keep the charge up...

I think the new pricing is over the top I'll be looking at converting a few of my resto batteries and see if the price becomes reasonable again...
