Yeah, I took a different approach from what I was originally thinking before signing off last night. Went ahead and just unplugged the charger and took a volt reading. It came in at over 13.9v, but still showing a red light (not fully charged). Then I kept taking readings about every 5 seconds (just a few times). The readings kept dropping, 13.7v, 13.4v, 12.9v. I just checked it about an hour ago, and it seems to be holding at 12.7v. I will give it some more charge time prior to my test crank, just to see if it is capable of a respectable crank speed.The normal maximum is 6 hours. A common problem is fluid loss, dry cells, no amount of charging will fix it. Two things to do, if you have a meter and know how to measure amps DC. Insert your meter in series and measure the charge current after 2 minutes. Measure the VDC after waiting 10 minutes off the charger. If it is less then 12.4 VDC, the battery is beyond hope.
One thing, I have removed the sealing strip and added distilled water. That on a 6 year old battery, I had other issues with charging and decided to replace the battery after 2 months of using it with the added distilled water. It still showed 12.7 VDC after sitting for over 24 hours, it would run the starter for a minimum of 6 times, each time 10 seconds long.
thing is there not junk just require servicing, suppose you could say the same with spark plugs why clean and gap them when there only a couple of bucks each but we seem to make them last a long time.I understan Dollars are relative to income ,but messing around re filling old junk is false econemy
In my post that was a going on 6 year old Yuasa AGM battery, filled by the dealer when purchasing the 2015 V650 Kawasaki. I have dealt with numerous styles of batteries over a 50 year period.I'm interested you guys are adding water to sealed batteries (not to be confused with "AGM") and those are very good explanations.Particularly vulnerability to overcharge and evaporation. The trick is discovering the problem as soon as possible and you guys must be paying attention to your batteries so good on you. It's possible to get 5 years out of the plain old Yuasa or a good clone if someone pays personal attention to it....
I bet 90% of the bad batteries that show up in spring are the result of poor maintenance and attention in the past summer followed by neglect in the winter.
anywho new battery has been filled with acid, let sit overnight yesterday, going to let it charge overnight again tonight, then sit for a couple hours tomorrow before throwing on the 500
what brand/part number battery?i bought a new battery in november and 6 months later it no longer holds a good charge,
firepower CTX14AHL-BS. looks like it has okay to bad reviews online, no surprises there. lesson learned though, next one after warranty runs out will be from a better brand or lithium ion for surewhat brand/part number battery?
)HOKAY DOKAY, almost got stranded a couple weeks ago when the bike struggled to start while warmed up. it's always had some minor electrical gremlins but i'm hoping it's been put to bed, battery got replaced under warranty (still some **** brand but whatever. shoutout to aprilia for his battery setup ritual, very helpful!), a mosfet regulator from ducatiman installed, cleaning and tightening contacts, and installing a pigtail tender to keep it permanently trickled, i'm hoping my bases are covered. readings are strong at the moment, will keep testing it and update if i find anything else. happy saturday everyone!
