Years ago.. When I worked in a bike shop we used to tell the customer to come back in about 4 hours to allow for charging when servicing new batteries.. Unless they really needed it and were using the bike as a commuter.. We would charge the battery during that time.. It really cut back on the comebacks.. Some guys would buy the battery. Install it, then complain about 2 weeks later when they went to use the bike.. ..Max
There is no need to keep the batteries off of concrete unless it's a hard rubber case which is porous and can 'leak' electricity. The plastic battery cases can't do that so no need to keep them off the floor.I got that info from an engineer at the battery company I used to work at.
I think it's a lot of worrying about nothing. Put the battery in the bike and go.
Can you not over charge a battery? If you put a battery on a charger for 7 days would it not over charged? Or is over charging from charging at to high of an amp? As is using a booster of 200 amps instead of 2 amps?Anyone ever herd of putting an aspirin in each hole of a flooded battery will dissolve or desolvate maybe it is, the crusties that weld the plates together.

Well that's what I did.My old battery died after years of faithful service. I bought a replacement, the Deka AGM battery and installed it right out of the box. The bike fired right up and I took it for a ride. Then I came home and parked it for a week WITHOUT hooking it up to the tender, I figured that it was NEW, an AGM Deka, it should NOT need to be on a tender. Well a week later the battery was dead. I thought I had a drain (I posted that thread and watched it turn into the usual here). So I hooked it to the tender and a day or two later it was fine. I was unable to find the drain on my own so I took the bike to a shop. They could NOT find a drain, and suggested that I should have charged my NEW Deka AGM battery before installing it in the bike. The guy said he has seen that before regardless if it's an AGM, HD, Deka or any other type of battery.Which is why I asked if even the NEW Deka batteries should be charged first.
So if I understand, AGM batteries do NOT need to be charged before install, correct?
Hotstick79,Absolutely slow charge a battery to full charge before putting it into service. Once you start a battery the first time, it will take a set at that charge and never go above it. You can ruin a voltage regulator trying to charge it. That's courtesy of Dennis Pinte (may he rest in peace), former product manager of Yuasa Battery. I charge at least over night or longer.

Incorrect, that is if you want a long service life from the battery.

I charge at least over night or longer.I believe this is true also.The Tender Plus was developed to correctly/fully charge an AGM battery prior to going into service. Some other charging methods will cause the battery to rise in temperature shutting the charger down prematurely.JB
The last two AGM batteries I installed came with a paper that said ready to use, but also that they were only charged 75% at factory so recommended to fully charge before use.
Someone needs to read the tech manual.http://www.dekabatteries.com/assets/base/0139.pdf
