Which? battery
 

Help! - My alarm had flattened the original battery on my '01 996s, so I decided to replace it with a new one. I was a bit confused as the bike manual says 12v-10ah, but my Haynes manual says 12v-16ah..I settled for a Yuasa 12v-10ah from Halfords, charged it up, but the bugger is wider than the original battery & won't fit!
Thanks for any advice, Illya.

Get yourself an Optimate as well!

Mine's 5 years old and still on the original battery ... and it has an alarm!

Not much help if you don't keep your bike near a leccy socket though...

Not a YTX9 as its to wide(deep) they fit my CBR600 and Fireblade fine but do not fit my 916 or my 998
My 916 has a normal lead Acid battery which is the 16Ah one, the 998 uses a sealed Battery can not remember the number of it and my local bike shop doesn't stock it as I found out a week ago.
So in the mean time I have fitted my R6 battery to the 998 which is the perfect size. On later 996s I think they also use this size sealed battery by fitting an adapter to the original 916 battery box.
If nobody does it before I get home I'll post the sealed battery ID number later

Battery is YT12-B4 according to http://www.motorbikebatteries.co.uk/

In 2001, the bikes were fited with a revised starter motor gear ratio that drew less current and made it possible to start the bike using a smaller battery. The starter gearing on the early bikes are not well suited to the smaller batteries.

Standard battery 1994 - 2000 model years:

Yuasa YB16AL-A2 (16 AH, 200 CCA, 11.5 lbs.)

Standard battery 2001 - 200X model years:

Yuasa YT12B-BS (10 AH, 125 CCA, 7.6 lbs.)

damn - mines a 2001 model and guess what? battery not quite up to the job this morning.....so which battery-guess if i look at it there are some serial numbers to identify it - goes on the optimate every 2-3 weeks at the moment. Probably combination of short trips,cold weather, lights on etc

Thanks guys - optimate not an option as the bike's kept outside & too far from a power point..The usual answer is to give the old girl a good run every 4 days. If I leave it any longer than this the datatool has drained the battery & there ain't enough charge to start her. Trouble at this time of year is finding a suitable 'window' - weatherwise.
I now have a brand new, fully charged battery which is useless to me. Ho Hum.

Hi ils,

Sorry to come in a bit late but I had this same dilemma and decided to go for a battery that was overspecc'd for my 996 to handle the shorter runs etc,l ie, less charging time and more starting. I went for the Odyssey PC680 (off the top of my head) it has around twice the cranking amps of the standard battery although is slightly heavier and slightly larger and I had to bodge up the mounting to get it in, all worth it though.

TP

I agree. I installed a Odyssey PC680MJ in my 916 in May 2001and it's tlll going strong. Highly recommended.

Am I weird because I have this warm tingly sensation after the almighty Shazaam agreed with something I said? :borg:

:alien:

Just a thought that might help when it's cold and the battery might not quite have enough in it to start the bike - I stand astride the bike, feet on the ground and shake the bike side to side - like you're warming your tyres standing still - it seems to shake up the acid and get a little more current to start the engine. This has even worked when I've had that ominous cough that says it's not going to turn over. Hope this helps you cold starters.

Thanks Webcore, It's worth a try in future. In fact I think it's probably more help giving it a shake prior trying to start it than the usual kicking I give it when it won't.

:lol:
Well funny

I have a dead battery at the moment and am about to put the sealed variety from the 998 as I bought a replacement a few months ago to kep for the 998 but now te 748 seems to be in more need than the 998 one, even though the 998 has a Meta alarm on it to drain it?

So does more ah mean more cranking power?
