Anyone used AGM batteries for the past few years? Thoughts?

[vtchequers]

I'm looking for a battery for a Yamaha Thunderace that I won on ebay, there was no (amongst other things) battery with the bike.
Any thoughts on AGM batteries?
There seems to be mixed reviews on the sites I've looked at.

Thoughts?

Unless there's a very specific reason for one I'd either have a lead-acid (cheaper) or a Lith-Ion (weight).

Personally I just always buy Yuasa batteries..... Fit and forget .... They Last forever

If it isnt lead acid, your Yuasa will will have been an AGM battery.

AGM is pretty much industry standard, lead acid batteries are OK, if Ok is good enoug but they need more maintenance and if that acid comes out of the battery,(usually if the bike falls over) it will wreck everything it comes into contact with...I did overhear a conversation a couple of weeks back where a dealer had cut a corner fitted a lead acid battery to a VERY expensive Ducati of the V4 variety and it had vented acid all over the frame and swingarm..

AGM batteries are known for great cold cranking power. Recommended fit on anything that's a bit lazy to start on a lead acid battery.

Yes agm is absorbent glass matt in the battery construction, what other battery would you fit ? That thunderace battery will be a fairly large battery

Replaced the OE battery on my speed triple with an uprated motobatt AGM 16Ah.. It's 14Ah standard on 2011 onward models. I use my bike all year and it lives outside, it also seems to overcome hot cranking issues where my old battery literally couldn't turn the starter motor at times. Seems 1050 triumphs are jippy gits with batteries in less than perfect condition.

Easy..I would fit any battery OTHER than a lead acid one..Your Thunderace battery isnt that large when you look at same of the batteries on the big Ducati's...Ive been buying and fitting Motobatts for about a decade now and have them on all my bikes, except the FireStorm, if that failed, id fit a Motobatt again , Yuasa are another good brand but generally more expensive for the equivalent Motobatt.

I have 2 brand new AGM batteries that I am happy to sell cheaper than I paid if anybody is after one (change of project direction). They are decent quality with excellent cranking power.
