Just got my new battery, it has no fill ports, is this good?

All the batteries that I've had in the past had the acid shipped separate and had fill ports. This one doesn't.

One concern is that I have no idea how long it sat with acid in it and I've been told that the separate ones have a very, very long shelf life because the acid isn't in it.

It also has a charge, but I don't know how strong. On the 10a charger, it's fairly strong, so do I do a slow charge with a 1 amp for a few hours?

I really can't see any advantage to them having the acid already in it. No telling how long it's been on a shelf. I guess I'll find out how long it lasts. Last one was about 5 years.

I suggest doing a slow charge until it is fully charged.

As a check before commencing the slow charge, I also suggest doing a voltage check, the number will be of some insight as to the present charge status of the battery.

I used the link you provided.
I see it's a AbsorbedGlassMatt type battery, thus explaining the factory fill instead of fill at time of first use.
I don't know much about AGM batteries, but the "absorbed" and "matt" words strongly suggest to me that the manufacturing process requires that the electrolyte be added as part of that process.
Classic plate batteries have their plates "immersed" in electrolyte and the space between the plates is where 99+% of it resides.
AGMs don't have large volume voids for the electrolyte, and my guess is that the word "absorbed" actually means weeny teeny pockets of electrolyte within the glass matrix, with a higher percentage of the total electrolyte volume being in direct contact with the anodic and cathodic materials.
I'm not at all surprised that there are no fill or top up plugs, as they don't sound to make sense given the design nature of the battery.
(as an aside, the use of high purity lead, especially antimony purged high purity lead, in classic lead acid plate batteries negates the need of water top ups over time - overcharging considerations ignored that is)

Hmmmm. I can't remember the last time I bought a motorcycle battery that did have fill ports.

Battery Tender. If you don't have one, you should.

I just pulled the 5 year old one and it didn't have fill ports. I didn't pay attention because I bought it already setup. The ones from Sears/Kmart and Amazon for my 700S had the fill ports.

Just did a compare of the old vs new. The old one was some $65 and had 8.5AH, the new one starts at $16 ($28 shipped) and has 8.6AH.

So it's < 1/2 the price and just as much power. It's just an issue of how long it'll last. Last one was 5 years, so even if I get 2.5 years, it's still cheaper.

Its an AGM battery, no acid needs to be filled, as it is absorbed in the matts
Faster recharge and better cycling compared to wet flooded batteries, so it should perform well
A little more sensitive to warm surroundings thou...

I've been using these AGM Motobatt batteries for a few years now. No drama, all good. I use them in my boats too as they are spill proof.

I just checked the old battery and it has the fill ports, so this is my 1st AGM type.

Those motobatt batteries sure do the trick. I have them in every bike. Very versatile and deliver great starting power. I usually use the second set of post/terminals to wire up a battery tender or other goodies...

FYI, the original 919 battery was an AGM battery that requires no acid fill before using.

First run with the new battery. She cranks faster, I can tell right off the bat. I guess 5 years is about tops for a battery

Hard to believe that I've already had this bike for 5 years. I only rode the 700S for 3 or 4.

I do not think think OEM bat is/was AGM. Just because no screw type plugs to fill later does not mean its AGM. Stock you fill it then put in non-replaceable plugs & it becomes sealed. Still does not make it AGM.

You may think what you like, but the fact of the matter is that the original parts manual calls out the battery as ‘Battery (YTZ10S).’ If you get a YTZ10S from Yuasa, it is marked as ‘maintenance free’ and if you shake it, it doesn’t slosh like a sealed flooded cell battery does. It’s either an AGM or gel cell battery. Since gel cell is usually significantly more expensive and offers little advantage and several disadvantages over AGM for a bike, pretty sure it’s AGM.

Especially since Yuasa says it is AGM. http://Www.yuasabatteries.com/batteries.php
