I have used this model for eight years and have never had a battery failure.
I've had quite a few battery chargers and this one is the best (in my opinion). They ain't cheap, but good stuff never is unless you buy Flipmeister stuff.
I have the model VEC 1093A. It gives up to 100 amps but for little batteries it idles down to 2 amps or less. It's a helluva charger for 120 bucks. I did have to replace the alligator clips. I inadvertently ran over them with the car. It has internal cooling fans and it's well made.
Once in awhile my battery on my 06' R3 will kinda pause while cranking, like it is getting weak. What is the best new battery to get for the R3?
Yausu gel cell good?
