how long do they last ? being driven every other day, I plan on driving it about 4-5 times a week

 

a few years. I've had mine for at least 3-4 years. Winter storage forces the battery to be on Battery Tender.

 

2 years now and still running great.....Same here during the winter it is on a battery tender...

If you don't go through hard winters it should be fine...I only had problems when temps are in the low 10f

 

It sounds like the first two guys who posted had better luck than I did with the PC 680 mini battery. I had two of them and I had a bunch of issues with them not holding a charge. At it's worst I had to unhook the neg bat. lead every time i drove the car or else it wouldn't start. --- And my car was a daily driver.

I ended up installing an optima in one or the rear bins. I haven't had starting issues ever since.

 

No problems here, have had the battery for about a month now, no complaints at all.

 

Going on 4 years now with no problems. I do disconnect it when the car is going to sit for over a week.
