I know a fair bit about batteries and charging systems, even with
the more recent intros of diversionary buzzwords, like Polimion, Yumion, but
I was wondering exactly what type of GSyuasa GT9B-4 12v/8amp battery I had,
excluding gel and flooded/conventional...
So I found the latest GS 6mb manual for my GSyuasa GT9B-4 and **GT
stands for AGM**
.....but the same battery form Yuasa YT9B-4 but NOT YT9B-BS is a MF-WET
battery and would lose some capacity/water if overcharged, and since GS and
Yuasa got together last year, I was getting confused about which changes
were made in my $200 GSyuasa GT9B-4 12v/8amp battery which is the Scooter's
specific and not aftermarket battery..
So I set the Shumacher 2/8/12 amp- AGM/Regular/deep cycle/Gel Float
charge to AGM. AGMs have almost no internal resistance to WET/Flooded
batteries, you can tell right off the bat....
The last GT/YT9B-4AGM I got was factory charged and the voltage
stayed at 13.6 volts, pretty good for $100, but a Batt high RC can start at
12.3volts but not the AGM.....
I took one old G/YT9B-4AGM apart some and seen the difference and am
still using it for secondary purposes..
