My conventional yuasa (12n5.5a-3b) battery life crapped out recently. Does anyone have a good recommendation for a maintenance free alternative?

My BikeMaster TruGel, 2 years now has been flawless. :twocents:
Was just looking at this gel after going to ebay for link to Sigma Tec. --- https://www.ebay.com/itm/Mighty-Max-YTX5L-BS-GEL-Battery-Replacement-for-Genuine-SigmasTek-ST5L-BS/132915667737?_trkparms=aid%3D111001%26algo%3DREC.SEED%26ao%3D1%26asc%3D20160908105057%26meid%3Dd3f7dec4ce0a4c3b8bcfd37d54422dac%26pid%3D100675%26rk%3D2%26rkt%3D15%26sd%3D323431066214%26itm%3D132915667737%26pmt%3D1%26noa%3D1%26pg%3D2380057&_trksid=p2380057.c100675.m4236&_trkparms=pageci%3A8ea0d0a8-189c-11ea-87c0-74dbd180c62a%7Cparentrq%3Ade4581a116e0ac3c6a9f425cffc92b3c%7Ciid%3A1 --- I've had a Sigma for at least 4 or 5 years no problems, hardly discharges at all just sitting.
I buy the agm's for a Yamaha Zuma 50.
Just pack some foam in the tray as they are a little skinnier.
About $35. Have sold them for years. I've had them last 5 years!! :righteous:

Yup.
After wasting time and money on lithium's, I'm back on the basic AGMs.
About $30 from BatteriesPlus and way more forgiving than Li. Keep it on a tender when you're off it for more than a few weeks and it'll last for many years.
Generally there is talk in the market that maintenance free batteries will not last on RD.s :umm:
not true. i had a sealed alarm battery last almost 8 yrs.
I like the Bikemaster AGM's. Mr Super Deals on E-bay is a great seller. Once my battery died prematurely and he helped me with the process of getting a replacement under warranty: https://www.ebay.com/usr/mrssuperdeals?_trksid=p2047675.l2559
Great! I think I'll try the AGM. The yuasa I have is 12v 5.5ah. I'm guessing the safest bet is to match this exactly.

5ah is fine. Doesn't need to be 5.5

I found these Motoclassic batteries on Amazon. One is not quite 5Ah, but the size seems compatible. There is also a 6.5ah version, but am not sure if the amperage is going to be too high.

I also found this one. Although it is 7ah, it says it's a direct replacement for my yuasa battery and that it will fit the RD350.
I am running a couple of Moto Batts. They are good batteries.
Motobatt makes great batteries. I have on in my KH400, about 5 years old and running strong. A little more expensive than Bikemaster, maybe worth the extra bucks.
ugh. I think I was mistaken about the direct fit for that motobatt. It looks like it might be too big.
$15. alarm battery for me .
arrg. I typed in the wrong battery part number (12n5.5-3b vs. 12n5.5A-3b) and I'm thinking the motobatt will be too large to fit in my battery box.
Does anyone have part numbers for a powersport battery that will fit? I looked at the sigma tek, but its seems like most are 12v 4ah. I haven't looked at the alarm batteries yet. They look like they are an easy fit, but I really don't know where to start looking on those.
Does anyone see anything wrong with either of these batteries? Is it bad to go a little over on amperage? My conventional battery is 12v 5.5ah.

The 4.5 is Sigma is fine but if you want 5.5 -- https://www.ebay.com/itm/Cannondale-440CC-C440-2002-2003-Battery-Replacement-By-SigmasTek/223058022168?_trkparms=aid%3D111001%26algo%3DREC.SEED%26ao%3D1%26asc%3D20160908105057%26meid%3D129c0c0482884c4cb284e802e8d9d469%26pid%3D100675%26rk%3D5%26rkt%3D15%26sd%3D254245443197%26itm%3D223058022168%26pmt%3D1%26noa%3D1%26pg%3D2380057&_trksid=p2380057.c100675.m4236&_trkparms=pageci%3Ac1596c8f-1a45-11ea-a96f-74dbd18008fe%7Cparentrq%3Ae92815a516e0a4cc0a4e1e0affda2711%7Ciid%3A1
ah.... I see its 4.5 not 4.0 for the sigma you sent over. Does the 4.5 inch width fit into the battery box well?
The stock yuasa dimensions are:
Length: 4 1/16 in.
Width: 3 9/16 in.
Height: 4 1/2 in.
I cut up a inner tube to wrap some around it, it's slightly smaller than stock one same height.

I've got a Motobatt MBTZ7S from a bike I bought for spares in my '74 RD350, small bit of foam used to secure it, jobs a good'un 👍

Hell yeah! Someone is with me! :righteous:
Long story short, the yamaha dealer gave me an AGM battery for free since my old conventional battery was under warranty. The one I got is the same (or very close) height and width as the old battery. The height and width fit perfect in the battery "mount/holder." I couldn't find the right foam, so I added some bike inner-tubes like one of the guys suggested to make up for the shorter depth.
The battery part number is CTZ7S Fire Power (replaces YTZ7S). 12V 6ah. If you are interested, I've attached a picture. Thanks again for all the great info!
I finally had time to install it. Hopefully I'll be shredding the streets soon :metal:
Problem solved and back on the road! Bundle up...
Wade
Is good news they honored the warranty.
