I am looking for YTZ6V and YTZ10.

Searching online returned wide gap in pricing despite what appears to be same brand/model.

Example YTZ6V can range from RM50 to RM120 for same brand/model.

YTZ10 can cost more than my car battery.

Any idea why the price gap and where can I reliably source these batteries?

pandai-pandai lo

see the shop why offer so low price, other merchandise on sale, reviews etc

if too good to be true, that's probably it

AGM batteries are twice the price even for normal car batteries, so if compare bike AGM vs car flooded, it's close

if want to reliably source, go to a reliable bike shop
if want reliable online source, check their warranty

Good batteries are hard to come by nowadays. Most of the cheaper ones dont seem to last long. Even if they do , you'd be lucky to get 2 years of service from hem.

My dominar is on its 3rd battery (ytx 9) the stocker lasted an astounding 4 years and it was still working when I swapped it out as a precaution to protect the rectifier. The green Tokio battery lasted barely 6 months (80). Now running a yuasa battery (130). Hopefully it does better.

On the NK , I just bought a ytx14zt lithium battery as the stock battery is on its last legs, dropping to 9v on startup if left unused over the weekend. Best to have a standby battery. Got it cheap from 6.6 shopee sale and some coin redemption. Paid 309 for it.

It is comically light though... But I bought it to offset some of the weight from my racks and panniers. My battery is mounted high in the tail so should help with bike balance going with a lighter battery.

If you are considering a lithium battery, bear in mind it does have pros and cons so it may not be suitable for all situations. Glad to explain if you guys want to know why.

Ironically stock batteries doesn't last long for me.

My bike usually left unused for 1-3 months. Usually I return to find the voltage below 9v and will have it charged up before firing up the bike.

Thought about lithium (LiFePo4 to be specific) but our standard charging system might not output the right voltage to charge it.
Please share your experience

Motorcycle Lithium batteries are built with BMS that is specifically designed with a bike charging system. That said, here are the pros and cons.

Pros
Very light weight, often smaller formfactor, doesnt leak, can be mounted every which way, even upsidedown.
BMS will cut off the battery if it falls below minimum voltage, protecting the cells (for L/A and AGM, once the battery discharges, sulfication occurs and damages the battery)
Low self discharge rate
Excellent amp draw

Cons
Equivalent Lithiums typically only have 1/2 the reserve capacity of same "sized" AGM. This is because lithium battery manufacturers follow the CCA of regular AGM to "size" the battery. My new lithium ytx14zt is 76whr, while the factory AGM is at 144whr. So read the specs carefully.
Not good in cold weather (does not apply to us, see below)
Can explode and catch fire spontaneously (hehehehehe.... especially charged when very cold) Lithiums need a short warm up to wake up (by turning on ACC and lights) before operating below freezing temperature.

So depending on your needs, if you got an infrequently used bike with inherent high standby draw (pretty much any new modern bike especially those with keyless, always on gps, security systems), Lithiums may not be suitable, but if you have a very old bike with no electronics, the low self discharge rate of lithium will be better. And all bikes will benefit from the much lighter weight.



If you have an infrequently used bike, in order to protect the L/A AGM battery, you have to invest in a trickle charger anyway. Any full discharge damage may be irreversible....as it may not charge up to full capacity anymore and it would only get worst over time. My cheap tokio Ytx9 has one full discharge and it turned into a paperweight, even using a pulse charger didn't bring it back alive. More expensive AGMs may be more resistant, but chemistry is chemistry.

Im still hoping Lithium battery manufacturers will put in a USB type C charging port so i can just stick a power bank and charge it. Sure they need a more complex dual input BMS...but I can dream.

Please plan a teardown of the Dynavolt once it's done
I thought the same, but... unfortunately, some Lithium packs don't actually have BMS

This isnt a battery issue man...this is a user issue...if u know ur bike is unused for 2 weeks or more u should really remove the terminals from the battery. Any battery u use will drain with that kinda non usage.

There are systems in ur bike that still requires some low amounts of power when the bike is off...like ur clock..internal memory for ur settings, mileage etc..

This is same for any vehicle...starting the bike/car at least once a week for 5-10 mins is more than enough to keep the battery alive. Also helps to keep ur internals lubricated.

Pretty sure something like the dynavolt battery will have a BMS. At least it says in its spec. Plus with the battery display, im sure its driven by the BMS.

Will keep the teardown in mind when its done for...if not just to humour you. Hahahaha

Hello TS, VRLA battery (YTZ series)cost more than conventional MF lead acid battery. Need to do survey in order to get better prices..

1 more thing.. if u plan to buy Yuasa YTZ battery, plz open the box & chk the DOM. Some shops has "over idling" (>8 mth) stock which can lead to shorter usage life span.

mostly are directly connected, with active balancer

I have installed a 2-way USB charger and it's working like a charm everytime I come back to charge the battery with my power bank.

Yes I am not prepared to open up the battery that's well hidden in my scooter to unplug it, and come home to reconnect it before I can use.

Thanks for the info.

Guess I will have to ride around to find the battery.

This is what I noticed too. It negate the purpose of leaving it unused for long period of time with slow drain from bike's electronics (e.g. alarm) even when bike is off.

maybe install a battery cut off switch at a more convenient location. the constant draining of the battery like that and recharging it can also reduce lifespan significantly

This issue is happening on all my vehicles.

so its user problem . hahahahahahahahaha


I would do what madmen suggests. Install an inline cut off switch. But then again you will loose the alarm.

Not intend to install the cutoff.

Gonna leave it as a problem

I use this in both our cars since my wife is no longer in the country and I seldom drive. Cheap and cheerful on Shoppee. For bikes however, there simply isn't enough room under the seat to accommodate this thing... if there is any in the first place.

The battery in my Ninja 400 died the other day and not knowing better, I got it swapped with the green Tokiohama, even paid 200 for it because I had someone send and change it without knowing how simple it was to replace myself. Was in the middle of work and didn't have time to check my options. Not sure if it's just a crappy battery or poor installation, but now my bike weirdly has to be in upright position to start normally, otherwise I would have to crank it 3-4 times just to start the bike.

Another astounding bit is that my bike was manufactured in 2019 and registered in 2022, and although it's seen little use, it's miraculous that the battery last 6 years. It's a FTX9-BS made by Furukawa Thailand.
