my 1300 battery just went dead, put it charging 1 minute ago...i will post back here when its fully charged.
i have also noticed that these batteries perform the same until they go dead. maybe the volt decline is so gradual that i dont notice it? TX, you said the go-go drops off somewhat noticable toward the end of the battery charge...have you noticed the same on the echo? unless my head is playing tricks on me, i dont see a decline in voltage.
I haven't actually noticed a drop off in vapor before the battery discharges either. I just seem to notice it when it needs re-filling. That is the only negative thing about an auto is you can't monitor the voltage but as long as it works good that is the main thing.
