Bad battery definitely force rectifier problem, that problem much more expense than battery replacement.Hopefully it is a bad battery and not a rectifier problem.
If your battery failed a load test (which your numbers says it did) then you can charge that battery for as long as you like, it will never be reliable. Time for a new AGM battery.Went and had mottobatt battery load tested yesterday. While unhooking battery i noticed the negative side post that screws into battery was loose. I took it down to local "battery power" store. It load tested at 120.
specs for mottobatt from what i am told is to test at 250 for starting.
Owner told me he would not stock mottobatt because it has not been a reliable battery. He tried to sell me a "Deca AGM battery" at $85. But, i
noticed the posts would not work with the Burgman 650. So, i brought battery home and put it on a trickle charge. I will keep a eye on it to see if it discharges again. Never had a problem with the OEM battery discharging like that if it sat for a month which is very rare for me.
I've had several bikes that have had the battery terminal work loose and I was sure I had tightened them tight.I had a flat battery a couple of times on my first Burgman 650
Took it into the dealers for them to check the battery.
The dealer found one of the battery terminals loose!
Never worked out how it worked loose because it was tight previously.
Never had a problem after that
11.7V is to low and 14.7 V is to high -> your battery has reached EOL and is worthless.Battery update: After 3wks time just went out and checked battery voltage.
Non running- 13.8v
Key turned on- 11.7v
Running at 5,000rpm- 14.7v
So, i believe my whole problem must have been a loose terminal i was not aware of.
As always i will keep a close watch on the situation and the terminals. Nothing worse
then getting stranded on the road with a Lardy.LOL
