Get an AGM acid battery, from a recognised manufacturer like Yuasa or Motobatt. I would not advise a LiFePO unless you are prepared to upgrade your regulator/rectifier. Andy
As with that one person who has smoked 100 cigarettes a day and lived until they were 90, I have had a lithium battery on my 996 for years with the original rectifier with no problems. HOWEVER it's a track bike only with no lights etc, the battery is removed and on it's correct charger when not in use. If you wanted to use one on the road I would change the regulator.
Worth looking at the starter cable (bigger is better!) if you haven't already - it was upgraded on my SP3 5 years ago and transformed starting and battery life...
Love the Lipo, never needs charging and the volts coming out of my regulator must be special Lithium volts because it works fine.
I’ve had batteries for a couple of bikes from Nigel at Bombatteries including one for my 916. He was able to give good advice and excellent service. He’s on 07768 466169. Cheers 2Twins
I'd go with the Motobatt (in fact I did), it maybe heavier than other batteries but starts first time even after weeks of no use and lasts well. I've got them on all my bikes, the one on my Guzzi weighs 10kg but the previous (8kg) battery would struggle to start it. The Ducatis are less battery hungry but slow cranking does no good for the sprag etc. and I 'm happy to sacrifice a kilo or so in extra weight for a bike that will start first time every time. Also replace the starter cables with heavier duty as that helps greatly.
my motobatt 16au just died after 3 years 3 months ,disappointed as have fitted these to everything and been pleased . the bloke at wemoto said because i was not using it enough , any thoughts ......people ? Ps Standard 95 916sp.
Sealed type gel battery for me. 60 quid a few years ago. Works really well and no topping up required.
