Battery flat - help!
Hi. It's only been 2 weeks since I last used my bike. I have just gone to start it and it won't start. Engine making no sound at all. I didn't think the battery would go flat after just 2 weeks of no use. Will I need to buy a new battery or will jump leads get it going again?

Re: Battery flat - help!
Don't jump it from a car battery.
Charge the battery with a suitable charger if you don't have another bike available.

Re: Battery flat - help!
You should be able to hook a battery charger to it and let it charge for an hour. It should have a surface charge by then. It needs a deep charge but should be able to start and run for the day. I have a battery tender I use on mine. Easy to connect and it let's me know when it is changed up.

Re: Battery flat - help!
Ive only just seen your post GN2. Just tried using jump leads from the car. No joy. The lights on the bike come on but absolutely nothing engine wise. If the lights are on, could it be that it's not the battery?

Re: Battery flat - help!
Check your battery leads first. Your lights can come on with very little juice in the battery, and even when you have a loose battery lead they will work. If the leads are tight then it sounds like the battery is really discharged. Check any additions that connect to the battery to make sure they are not pulling some current unknown to you. I have seen batteries so discharged that jump starting was not an option simply because all the juice was going into the battery but not coming out of it to complete the circuit. Stick it on a charger, and if it doesn't charge after an hour of quick charge, it is bad.

Re: Battery flat - help!
I did have a bit if difficulty clamping the leads onto the bike battery as there is not a lot of room for them to clamp around the metal bits so I'm not even sure if I connected them properly. It was also dark so difficult to see what I was doing even with a torch. I don't have a charger so I may as we'll just go and buy a new battery. Do you know how much they are?Mel46 wrote:Check your battery leads first. Your lights can come on with very little juice in the battery, and even when you have a loose battery lead they will work.

Re: Battery flat - help!
Is it possible that it could be the alternator? Considering the bike was fine 2 weeks ago when I used it last, a flat battery seems the most likely explanation.

I do not see in your location profile where are you from, but if you're from the States, I guess that they will be even cheaper...

Re: Battery flat - help!
We purchased our Battery Tenders (2 of them) from bikebandit.com when they were having a pre Christmas sale. Keep an eye out for online sales at motorcycle/scooter stores and pick one up. I think we ended up only paying atound $15 each at that time. They are well worth it. I don't know how strong the batteries are that come with these scooters but I have seen other reports of battery problems on 2013 pcx scooters. Maybe there was a bad batch of them. Even the battery on mine, which is only 4 months old, has been failing lately. I have it on the battery tender right now, but it looks like I will be replacing it soon anyway.

Re: Battery flat - help!
I'm bringing my 2013 150 into my dealer in about two weeks for them to run some tests on the battery, letting it fully drain, etc. I had them install a trickle charger for winter storage, and that's been working great. But I left it disconnected from the charger over a long weekend, and in 4 days the battery was dead. No way should this be happening on a year-old batt, when other members here say they'll go weeks or months without a ride and start up no problem.

Re: Battery flat - help!
A battery going flat in so little time isn't normal... here in Europe, with the start and stop system, the old PCXs had this problem (rumored to have disappeared in the 2014/2015 model), but US models, without the system, should not have it...
My other scooter, a 2009 Suzuki Sixteen 125, is still running on the original battery, and the bike is not used for weeks in winter (I have two scooters), so definitely is not normal to have battery problems in so little time...

Re: Battery flat - help!
Right, Ive put a battery charger on it and the lights on the charger are green indicating that the battery is fine. Put it back in the bike and still won't start. Sadly, it would appear that it's an electrical or wiring issue. Garage are coming to collect it.

Re: Battery flat - help!
How much of a clown do I feel! The garage have just come out. There is nothing wrong with the bike. I was trying to start it with the stand down!!!! I guess you forget the routine when youve not been on it for a while!
