Condor Posted October 17, 2015 #2 Posted October 17, 2015 Very good video. There were a few areas that I disagreed with, but for the most it was spot on. I also bought a bike that came with one of those 'Made in Taiwan' Bike Master batteries and it was junk. The recommendation at the end rating the AGM the best for our needs was right, but I'll buy Made in the USA....
Great White Posted October 17, 2015 #3 Posted October 17, 2015 Anyone else think it's funny that the lithium battery label says "lithiumion" and they go on about how it's a "lithium iron phospate" battery?
BlueSky Posted October 18, 2015 Author #4 Posted October 18, 2015 I bought an AGM Walmart (Everstart) battery for my ZN700 about 4 years ago. I was really impressed by its power and longevity. It was made by Yuasa and the acid came in separate tubes that I had to add to the battery and then charge it slowly unlike what they said about AGM. But, like I said i was so impressed that my car and my truck now have AGM batteries. My Venture came with an AGM when i bought it 1 1/2 yrs ago and it still seems to be hanging in there.

AGM Batteries are sealed and do not need to be activated, and they can be safely shipped by common carrier. If you needed to add acid you don't have AGM's....

Read the link. http://www.atbatt.com/motorcycle-batteries/how-to-fill-and-charge-yuasa-ytx14-bs-motorcycle-battery I scanned the article, and if you want to buy a battery that you have to jump thru hoops to activate, be my guest. I agree'd with everything in the article until they said it was an AGM being used for the demo. Call if what you may, but in my opinion the thing isn't an AGM in every sense of the word. It's more like one made in USA.... USA Japan. If that is a dry AGM Yuasa battery that needs to be handled carefully, all they are doing is making the consumer do what they should be doing in the first place. Not all AGM's are the same....
BlueSky Posted October 19, 2015 Author #8 Posted October 19, 2015 After the acid is added to the glass mat and charged it turns into a gel like battery just like the other AGM batteries. The plugs that come with it seals it. When I bought the Walmart Everstart Yuasa, that was my first AGM battery. I'm very happy with it. And I wouldn't hesitate to buy another one just like it. My Dodge Magnum, F150, and Boston Whaler all have AGM batteries now and they all came sealed and charged.
Condor Posted October 19, 2015 #9 Posted October 19, 2015 Ok, first of all an AGM battery does not have gel in it. It is a liquid, and stays that way. One reason gels don't last is they can not deal with any gassing which usually occurs on a charge voltage of 13.4vdc or higher. It takes a rectifier that will limit the charge voltage to around 13.2vdc just to be on the safe side. With an AGM if any gassing occurs, and being in a liquid state, the hydrogen (i.e. gas) will rise to the surface and escape thru a valve. In a gel battery the bubbles with stay suspended in the gel and on the plates, eventually causing the battery to fail prematurely due to less contact between the acid/gel and the plates. Our Ventures usually have a charge voltage of 14.2-14.4vdc. A death environment for a gel cell battery.
BlueSky Posted October 19, 2015 Author #10 Posted October 19, 2015 I agree, Gel was the incorrect term to use. But, the glass mat is 95% saturated with the acid and it will not leak acid even if broken.
Condor Posted October 19, 2015 #11 Posted October 19, 2015 It all depends on the size of the plates and the thickness of the mat. A good way to tell the difference between a good AGM and an 'El Cheepo' is to check the weight. Cheap AGM's weigh a few pounds less than a good quality AGM. Off shore battery manufactures will use less lead and thicker matting to make it cheaper. It still qualifies as an AGM, but unfortunately they will not perform as well. Ya get what to pay for... A little side remark. It always amazes me that someone will go out and dump thousands when buying a Venture... or others for that matter... and then shop for the cheapest damn battery they can find when they need one.
Prairiehammer Posted October 27, 2015 #12 Posted October 27, 2015 If you needed to add acid you don't have AGM's.... Not true, Jack. Currently, YUASA sells some of their AGM batteries dry along with a separate acid pack. For instance, the YTX24HL-BS for the First Gen Venture. Other YUASA AGM batteries are "factory activated" (shipped with acid inside).
