bkk6060 Posted January 6, 2020 Share Posted January 6, 2020 I am starting to hate this bike. It has the keyless electronic start mechanism. If I let it sit for a week, the battery is dead. This can happen in the "off" or locked position. It has happened 6 times now. Any suggestions? Is there possibly a more powerful battery I can buy? It is a PIA to push it to get it changed or recharged whenever I get back from a trip. Link to comment Share on other sites More sharing options...

Could be the present battery age, if not you may have an electrical leak fault draining the battery. If it's a thing that happen with them scoots get a trickle charger set up sorted.

The other times I charged them which took half a day. So, either something is slowly sucking the juice or the batteries just are not holding their charge.

If you can't check voltage leaks yourself get it checked to see if there is a fault which sounds like it to me. Some aftermarket electronic stuff can drain batteries quickly e.g. alarms. Get hold of Yuasa battery which find long lasting if it don't you definitely have a fault. Link to comment Share on other sites More sharing options...
papa al Posted January 8, 2020 Share Posted January 8, 2020 Three things: 1. Lithium m/c batteries are available. or b. Wire in 30 cm jumper leads to storage compartment. Keep one of those 4 new batteries charged as a jumper. but 4. Prolly just need a screwdriver to disconnect tho. Farang think too mut. 1 2 Link to comment Share on other sites More sharing options...
fpexpert Posted January 8, 2020 Share Posted January 8, 2020 You must have a battery drain problem, i've had mine for 2 years now and on the original battery and can leave it a month and it will still start on my return! 1 Link to comment Share on other sites More sharing options...
Popular Post Moonlover Posted January 9, 2020 Popular Post Share Posted January 9, 2020 (edited) If you had a puncture in a tyre, you wouldn't keep putting air in it would you. No, you'd get it fixed. That's the best analogy I can think of right now. Clearly your Aerox (not an Aero, that's a chocolate bar) has a fault that is draining the power from the battery. Either that or the charging system is faulty. (Have you checked the voltage on the multifunction display?) Continuously buying new batteries is futile as is recharging. I've just had a read of the owner's manual and it says the following: The battery is a Valve Regulated Lead Acid (VRLA) type and must be charged using a special constant voltage charger. A conventional charger will damage it. So please get the bike back down to the Yamaha dealer and get it sorted. You might have difficulty explaining the problem, but be persistent. Good luck. They're great bikes and I hope you can get this issued sorted. Edited January 9, 2020 by Moonlover 3 Link to comment Share on other sites More sharing options...
Moonlover Posted January 9, 2020 Share Posted January 9, 2020 I had further thoughts on this whilst out riding (on my Aerox) today. O/P, please let me know how long you have had your motorcycle and how old was it when you first had this battery problem? I'm also curious to know whether you fitted the same type of battery as is originally fitted by Yamaha when new. Link to comment Share on other sites More sharing options...
CGW Posted January 9, 2020 Share Posted January 9, 2020 You have a problem, short somewhere! may well be difficult to locate, though not impossible. Either you can fix the problem, keep buying batteries or you could plug in a trickle charger every time you leave it. Link to comment Share on other sites More sharing options...
bkk6060 Posted January 9, 2020 Author Share Posted January 9, 2020 Thanks for the responses. I am stupid have no tools and have no idea how to disconnect the battery. Guess I need to figure that out. I do agree it is a great bike just this PIA issue keeps happening. Link to comment Share on other sites More sharing options...
papa al Posted January 9, 2020 Share Posted January 9, 2020 Prolly unscrew a access panel under seat then unscrew the lead to the battery. Screwdriver 35 baht if no kit supplied. She'll be right mate. 1 Link to comment Share on other sites More sharing options...

How long had you owned the motorcycle when you first had this problem and who replaced the battery for you? Link to comment Share on other sites More sharing options...

The batteries were new I saw the box, battery, and receipts. A guy with a small shop near me replaced them. All worked fine for awhile then the issues occurred after the bike sat. Did not want to get into it more but the gf in khon kaen has the same bike and has had it die out twice. Maybe just bad luck. Like I mentioned I think it has something to do with the electronic starter. Who knows. Maybe a keyed system would not have the issues. If started every few days though, never a problem.

Thanks for your answer. Interesting to note that your GF has had the same problem. So, what you need to check is whether your local Somchai has fitted the correct type. These machines have sophisticated electronics and having the correct battery is very important. So, open up the seat and find a black panel just forward of the storage bin. Remove the lid (2 cross point screws) and check the battery type. It should be a Yuasa YTZ7V. If it isn't that could be the cause of your problem. (See photo) If it's the wrong type I strongly suggest you replace it with the correct type. If you can't get one from your local guy, they're available from Lazada. Good luck and please let me know how it goes. 1 1 Link to comment Share on other sites More sharing options...

You're probably right, but I don't have a list of compatible batteries available, so I'd rather suggest the one that is known to work. The original type as fitted by Yamaha. The O/P has fitted 4 inferior batteries so far. Time to 'stop the rot' and start enjoying his Aerox again. Link to comment Share on other sites More sharing options...
kekalot Posted January 14, 2020 Share Posted January 14, 2020 this might not be relevant but.. back when I had my Aerox, I plugged in a USB charger in the electric port the left side (I don't know the correct name) and within a few days my battery was dead. (like proper dead) I am not 100% sure but it might have been the adapter draining battery power somehow anyways I replaced it with a battery that was a little bit higher (but same size) from some local mechanic shop (was like 650 baht or something) and removed the USB charger thing and never had issues after. wish I could tell you the battery model but I sold it a few months back for lack of usage (nothing wrong with bike) 1 Link to comment Share on other sites More sharing options...
globerunner4 Posted May 9, 2020 Share Posted May 9, 2020 Hi, new Aerox owner here. If your bike is sitting for a week at a time try this quick disconnect. Can find on Lazada. I purposely got the R version without keyless or ABS to avoid all the extra stuff that could go wrong (and cheaper). Good luck 2 Link to comment Share on other sites More sharing options...
Henryford Posted May 10, 2020 Share Posted May 10, 2020 I've just got an Aerox (which i think is great BTW). I note in the owners manual page 5-1 regarding the stop start system it says "When parking the vehicle or leaving it unattended, be sure to turn the main (stop start) switch off. If the Stop and Start System is left turned on, the battery could become discharged". Does everyone turn off this switch when they park. Easy to forget to do. 1 Link to comment Share on other sites More sharing options...

The manual actually says 'be sure to turn the main switch off'. The bracketed 'stop start' is your own addition. On that same page fig 1 clearly shows the main switch, fig 2 clearly shows the stop/start system switch. The difference is obvious. I think you're misinterpreting what you're reading. At the practical level, I've had my Aerox for 4 months and it has never occurred to me to switch off the stop/start when parked up. Same is true of my Honda Click which I've had for 5 years. Yes, the Aerox is a great bike. Have lots of fun. ???? Link to comment Share on other sites More sharing options...

So there is only a danger of the battery discharging IF the stop/start button is left on AND the main switch is NOT turned off. Link to comment Share on other sites More sharing options...

That's correct, the main switch will isolate everything when switched off and if you have the smart-key version it will nag you persistently if you forget to! Enjoy your riding.

kekalot Posted May 11, 2020 Share Posted May 11, 2020 (edited) wanted to add that on my particular model of 2018 ABS Aerox you could display the battery voltage instead of trip information can't recall exactly how much it should be displaying cause I don't have the bike anymore but from Google it says something between 13.7 to 14.7 volts if it doesn't then probably something wrong with the Stator. but I'm not a mechanic (and far from it), I just had to lookup most of this stuff after I left the USB charger in the bike for too long and my battery had to be replaced. so someone else might correct me Edited May 11, 2020 by kekalot Link to comment Share on other sites More sharing options...
