    Correct Gen3 battery?

    Ok, this seems like a really elementary/stupid question, but can anyone confirm which battery fits my 2018 XRT?

    This is the first time I'm buying a new battery for the 1200 (been through at least 1 or 2 with the 1050), and what's current installed is a Yuasa YTX12-BS:



    (taken from right side of bike, so negative is towards front)


    Now the interesting part is that if I check Yuasa's website, they say I need something like a YTX20L-BS

    https://www.yuasabatteries.com/batteries/search-results/?vehicle_type=motorcycle&vehicle_make=triumph&vehicle_year=2018&vehicle_model=tiger-explorer

    The YTX20L is both slightly longer and taller than the YTX12, and the 'L' indicates the negative terminal is on the Left side (so opposite the YTX12). I've been buying BikeMaster AGM/Gel batteries for years, so I checked their website. Nothing listed for my bike. I found other info on the net that maps their AGM MS12-20L-BS to the YTX20L-BS, and their physical size matches, so I pulled the trigger... I'm not sure what I expected, but I now have the MS12-20L-BS in hand and don't see how it would work. Since I found nothing saying the YTX12 was the right battery I kind of assumed that the PO just put a smaller, cheaper battery in and maybe yanked the cables around. I double-checked the owners manual, and it doesn't seem that a L battery is expected. See below where it indicates that the negative terminal is on the Right side (when you're looing at the batter with the terminals closest to you).




    I'm also somewhat interested in Lithium. My latest bike, a 2018 KTM 690 Duke, came with an Antigravity battery, installed by the PO, and it has been great. Starts up strong every time and has maintained a charge all winter so far with no tender. Antigravity's website recommends their ATX20-RS. That model is very similar in physical size (6.8" x 3.4" x 5.1") to the YTX12...

    So, which battery is this bike really expected to take?



    Site note: why is the Gen3 treated like such a bastard when it comes to parts finders? Half the time the XRT isn't even listed (though I know that almost never matters for most parts), and sometimes even the 2018 MY is missing! In fact, Yuasa doesn't list any batteries for the 2019+!

    My original 2018 XRt battery is a Yuasa YTZ14S.
    +ve is on the left hand side with the terminals closest to me.
    It is rated 11.8Ah.  (Looks like yours is less.)

    Because I'd flattened it completely and didn't trust it (don't ask), I've replaced it with a non-Yuasa (too expensive) marked VTZ14S.

    Thanks, so it came from the factory with the Yuasa YTZ14S?

    https://www.yuasabatteries.com/battery/ytz14s/

    doesn't list any Triumph bikes  :003:

    Maybe I was right about the PO putting a smaller, cheaper battery?

    I should also note that the Antigravity website only lists "Tiger Explorer" 2012-2017, and the recommended ATX20 is listed as mapping to, among others, the YTX20L-BS.

    I guess I'll start a list to help me keep in straight in my head:

    https://www.yuasabatteries.com/battery/ytx12-bs/

    https://www.yuasabatteries.com/battery/ytx20l-bs/

    https://antigravitybatteries.com/products/starter-batteries/restart-oem/atx20-rs/

    YTX12-BS          6 in. x 3 7⁄16 in. x 5 1⁄8 in. (150mm x 87mm x 130mm)
    YTZ14S              6 in x 3 7⁄16 in x 4 3⁄8 in (150mm x 87mm x 110mm)
    YTX20L-BS        6 7⁄8 in x 3 7⁄16 in x 6 1⁄8 in (175mm x 87mm x 155mm)
    MS12-20L-BS    6.8 in x 3.4 in x 6.1 in (175mm x 87mm x 155mm)
    ATX20-RS          6.8 in x 3.4 in x 5.1 in

    So, I looked up some Triumph parts diagrams and found the stock battery part numbers. Searching for those Triumph part numbers gave me a couple of references to YTZ14S, which hopefully means that is the correct stock size. Based on that I ordered a BikeMaster TruGel MG14ZS. The YTZ14S/MG14ZS is listed as roughly the same size as the currently installed YTX12-BS (albeit a tiny bit shorter) so even if it's not the correct battery, at least I know it will fit.

    I was almost going to buy a Yuasa AGM YTZ14S, but they're $200+, very close to the price of one of the lithium batteries!

    I could not find the battery I needed on Yuasa's website (2020 Triumph Tiger Desert Edition). I took the seat off and mine uses a YTZ14S too.

    Just as a follow up, the MG14ZS I ordered arrived, and I installed it last weekend. Fits just fine. The only issue for me is that my rubber hold-down strap seems to have been stretched out from the taller YTX12. I'll have to figure something out there.
