New 50cc Chinese Scooter Wont Start ( Is Hissing ) By straightbangin (Read 16,535 times)

so what do u suggest gatekeeper?

[gatekeeper]

Well I use a 5 amp hour battery in mine and I haven't had a problem in 5 months since I put it in. However, We don't get near as much heat in Washington State as you do down there. (Rats!!) And there I am wondering whether or not the charging system in these 50cc scoots is up to being able to keep a 9 amp battery fully charged, especially with the kind of riding you do. Sometimes bigger isn't always better. (I know, say it isn't so!!)

If it was me I'd put a dress on your scoot and bring her inside at night and hook it to the charger. If your landlord complains, tell him she's your sister!

Seriously, If you think you need a new battery I would still go with a 7 amp hour since it fits in yours. Get the AGM type as the tend to hold a charge a little better than the conventional ones. Like I said earlier, some of the original equipment brands don't last too long once they are put in service. I got my battery from TMS Motorsports off of Ebay. Don't know if their 7 amp ones will fit or not, I'll have to look.

Do you have a volt/amp/ohm meter to measure your scoots charging output? If you don't you can get them for under 10 bucks at places like Harbor Freight. Handy things to have around the house.

Extreme heat, extreme cold and short trips are hard on batteries for all vehicles, not just scooters. So you are batting 2 out of three.

Maybe the dress isn't such a bad idea. ;D

Haha I couldn't sneak him in if I wanted too. Can't lift him up the stairs

What does AGM type mean? Thanks.

[gatekeeper]

They are a maintenance free type battery that uses a type of matting inside making them almost spill proof. they come loaded, no fluid to fill before use. They tend to last longer than conventional lead acid batteries.

[straightbangin]

oh cool thanks.

[straightbangin]

I've got my eye on this one right now

www.ebay.com/itm/BATTERY-12V-7AH-F1-TERMINALS-187-RHINO-AGM-EACH-/390192631328?pt=US_Batteries&hash=item5ad94b0e20

At least if I buy a new battery and that one also hates me I will have 2 so one can always be charging or charged while the other slowly plots against me & also its not too hard to get in and out

[gatekeeper]

Here is an AGM type:

Here is a Gel type:

cgi.ebay.com/ebaymotors/GTX7A-BS-CTX7A-BS-YTX7A-BS-7A-BS-Cygnus-Scooter-Battery-/150659103025?pt=Motorcycles_Parts_Accessories&hash=item2313fb7931

Both are maintenance free. Both provide more starting power over conventional lead acid batteries. The Gel type can even be mounted upside down with no ill effects. The Gel type also seems to perform a little better over a wide temperature range. I have one in my Adly 150 because the battery mounts sideways on that one. If it didn't I would probably just use an AGM one in it.

Both these two batteries have the positive/negative poles reversed from the 5 amp I use in my 50cc so you would have to be sure your cables are long enough to fit properly. Hmm, or just turn the battery around.

I think for your scoot the AGM type is a good fit

These types of batteries are not designed to be used in motor vehicle applications. They are used in the electronics industry for back up power supplies. While they may "work", they would probably wear out pretty quickly. They are made to put out a little power over a long period of time, not the short bursts of high power we use for starting engines.

These are the types of batteries used in portable jump starters. Some of these jump starters are rated at over 1000 amps starting power. The tab style connector isn't so good for multiple connections, but the battery is capable of all the power you need for starting. As with all AGM batteries, charging voltage is more critical than with wet cell batteries.

gatekeeper wow the gel one is snazzy looking You dont think i should go with gel because it performs better over a wide temp range or does that mainly mean for colder temps?

cruiser thanks. what do u mean by charging voltage more critical? as in better than? I guess mine is wet cell, i don't know. I had to add an acid pack

[gatekeeper]

You may be right Cruiser. I have never opened up one of those portable jump starter units. They do look like those batteries I've seen in emergency lighting units and alarm systems, made to put out a little power over a long period of time.

They are supposed to perform better in both extreme cold and extreme heat. Something I can't attest to living in Washington State. Does look pretty cool though doesn't it.

The reason I have it in my Adly is because of the sideways mounting. No possibility of spills.

[Cruiser]

When charging an AGM over a long period of time like in winter storage, the charging voltage has to be maintained in a specific range in order to avoid damage to the battery. In everyday scoot use this does not seem to be an issue. I believe some AGM batteries have to be filled by the purchaser. If your battery has no vent tube, then it is an AGM type. The cap for the filler holes usually is a one piece unit which snaps into place and is never taken off during the life of the battery.

I have replaced the battery in my unit. They are the same type batteries found in alarm systems and emergency lights.

[straightbangin]

I use my scoot 2-6x a day and its always warm to hot here ( well we get about 5 cold days randomly in the winter but thats it )

It doesn't have a vent tube and ya the cap for the filler holes was a one piece unit that snapped on and that is not supposed to come off again.

I'm just tryin to decide what battery to get next I go on short trips because my neighborhood / where I can drive this scooter is so small so main thing is a scooter that can handle ( or handle as well as possible ) multiple starts w not a lot of drive time in between. I'm def glad i bought that charger though

I just want to make a point , the battery's that you have to add the acid , they tell you to charge them and test them in a very particular way . From reading the post (correct me please) It looks like you may have just bought a charger ? If that is the case then it seems you would not have been able to correctly charge the new battery and test the new battery . This could be the reason that your having the trouble your having . I also read that you were or have just bought a meter .

With the above said , your on the right track , I don't believe in offering a female a bone (that would be disrespectful) I think you are doing everything you can to help yourself, how about a high five . I think your video's are great and the information your providing is great . This helps all of us help you .

I'm not sure where you live if theft or tampering is not a problem where you keep the scooter , one of the solar chargers maybe an idea . Well being that the Bendix wasn't the problem and you have been all over the place , you should feel no intimidation about the machine . That in it self put you in a great place .

I don't think you need to go fancy with a battery just do what is recommended before first use .
