Modern Vespa

Im confused. I have a 2007 GTS and 2006 BV250. Both bikes have a Yuasa YB10L-BP battery in them. In the GTS workshop manual it shows an YTX 12 or 14. Anyone been thru this that can give me words of wisdom?

I wouldn't be surprised if its a typo.. my 300 and 150 both have 12 written on the batteries..

One of three things could be the answer:
1. Yuasa didn't come out with the YTX 12 or 14 until after your manual was printed
OR,
2. They didn't have any 12 or 14 models in stock so they put in the closest thing that they had at the time.
OR
?????????

My BV500 also calls for a larger battery but it has a 10 amp hour battery. Don't know if the dealer changed it before I bought it (used) or whether it came that way from the factory. It works just fine so I don't give it a second thought but when it comes time to replace it, I'll replace it with a 12 amp hour model.

I just replaced the stock YTX12-BS battery on my 2006 GT200 with a YTX14-BS battery. The new battery was about a 1/2 inch taller so all I had to do was remove the battery tray and put a piece of rubber (about 1/8 inch thick) in it's place and it tightens down nice and snug. You can usually find this rubber pad in the plumbing department of a hardware store, it is about 6 or 8 inches square. You could also use cardboard I imagine. I have no idea what the rubber pad is normally used for. A little more cranking power might help since I have to engage the starter with the headlight drawing 55 or 65 watts. I haven't got around to modifying the headlight to go out while engaging the starter as yet. Both these batteries have the positive terminal toward the rear of the scooter. If you scooter has the positive terminal toward the front then you need the YTX14L-BS. I am a firm believer in the most powerful battery I can fit in my scooter since kick starting is not an option. I hope this helps you.

Based on my understanding of battery nomenclature BS in YTX12-BS is the terminal designator so a YTX12-BS could be used to replace a YTX14-BS or YTX10-BS if the battery can be made to fit

If you have a YTX12-BS you can replace it with any ###12-BS battery as the YTX is the designator for a battery manufactured by Yausa (regardless of the name on the side of the battery). In this case the 12 is the amp-hours and the BS are the terminals.

If you have a YB10L it is an acid bath, YTX12 and 14 are sized differently and you would need a new tray and possibly have to lengthen the cables. A solution is available in an AGM sized exactly as your acid bath. I'm pleased with it and so are several others.

Need battery for a 2006 Vespa Piaggio 250cc GTS

Did some GTS research when my new 2009 GTS came with the wrong battery. My 2009 GTS uses a YTX14-BS, but the dealer installed a (too short) YTX12-BS. Some GTSs from other years use a YTX12-BS.

What I can't say is that the YB10L-BP is the wrong battery, as for all I know it _might_ be used in some GTS models that I missed in my research. I'd suggest checking the fit, and if it fits well, then use it. All three of the batteries mentioned above are different sizes and of varying capacities (10, 11, and 12 Ah).

Yuasa's web pages list battery specs including dimensions, such as this one for the YTX14-BS: http://www.yuasabatteries.com/battery.php?bID=B12&vID=3786

It has been reported that 3 batteries may have been used in what are called 2007 model GTS. YB10L-BP is definitely one of those used as you can read in the topic I posted the link to.

GTS Battery Options

I just bought one of these...

http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=110463069116&viewitem=&sspagename=STRK%3AMEWNX%3AIT

AGM type....and 4 poles.

Bought it Thursday on eBay and had it in the bike Monday night...had to trim the connectors a bit so the holes aligned but the install ended up very clean.

Solved the starting/idling ugliness.

Hope it lasts as well as the original.

I found that brand/supplier too, but got spooked by their BBB report. I'm glad it worked out!
