hello stevenjayne, i've had my quattro for a couple of years now and i keep telling myself that i'm going to try out some alkaline cells to see if there is any diff. in use time, but u know what..... i have been so happy with my rechargable NiMh batts. the same ones I bought a week after receiving my Q. that frankly my Q has never seen alkalines. I also prefer them over my quatro/ explorer factory rechargable battery. (the 2500's last longer) I think the 8 batt. Vanson charger is worth it's weight in gold. good alkalines are not cheap no matter where u buy them. the only thing I would like to add to the arsenal is a quick charger such as edjcox mentioned. I was just never sure if it would charge as well as a 18 or 19 hour charger, I mean if they work as well... why do they even sell long hr. chargers ? now that i know that they work ( right edjcox ? ) i will be getting one. I have picked them up & looked at them 20 time at home depot lol. wish they made an 8........ picky, picky, picky. good luck out there all of u.
