I’ve replaced my battery at least 5 years ago now after the original one went bust. I bought Shorai Lithium replacement. In all this time it never went flat, nor I needed to recharge it once. I ride the scooter seldom now maybe once a week if that on a short run about and this battery keeps giving and giving. So if you’re looking to replace a battery than Shorai lithium is highly recommended...

Thanks for the tip, Pcxdemon. I'll put them on my list.

Be careful with lithium, they don’t like the cold......

Also, if you replace it with Shorai (trusted) or other Lithium version, get a higher cca upgrade. Cant hurt having more cca on tap..

Seems scooter (bike) lead acid batteries can be replaced with Lithium ones, but normally, Lithium cells need specific chargers and charging schemes as they suffer from earlier failure if the cut-off point for switching to less charge is not adhered to. Still, if they work, great.

Lithium battery, over 5 years running (no charge top ups) and no signs of demise. Can’t get normal batteries to last that long, 2-3years max if you’re lucky.

My PCX is nearly four years old, kept outside on the drive and is still on the original battery. Starts 1st time and runs well. Guess there are just some poor batteries from new.

I think it's like anything else. . .use it or lose it.

I believe riding the thing every day is better for the battery. . .keeps it alive. . .than letting it sit for periods of time.

It's the one thing I dislike about snow and salted roads where I live. . .I have to let my scoots and bikes sit until things clear up or otherwise risk rust and corrosion galore. I use my MOPED mostly during the winter because it's mostly plastic (when the roads are not dangerous). But the other machines still look good and I'd like to keep them that way. Occasionally I trickle charge though. Just my 2 cents. 8)

I can hear what you are saying re:salted roads and corrosion--I live in Northern Illinois where the salt flows freely the winter through. Still, I use my PCX every day (provided the roads are clear) for at least 15 to 20 mins and sometimes longer for no other reason than I love riding. I know the saline slush on the street gets splashed on the nether parts of the bike where said salty slush will do its nasty work, but, to me, it is worth it even if it shortens the life of the machine somewhat. I wonder if leaving it parked in the garage unused for 4 or 5 months is any better for it than salt splash?

You are indeed a true "rider". . .not just an "enthusiast". ;)

I do ride all my machines throughout the year.

But when it comes to the Bandit and KLR I am kind of picky now because I may end up going to some Vintage meets and when I do I want them to still look good. I probably won't enter them in any competition but I'd like them to be good enough for people to say "Hey. . .why don't you?"

I foresee having the PCX for a long time. . .as long as I can still throw a leg over the saddle and still ride. Parts are widely available and it has a timeless design. I like keeping that one clean as well.

My Genuine Roughhouse. . .it's a different story. It just looks like it's ready to go "off road". . .a bit like the old Yamaha Zuma 50. It gets the job done and serves me well. . .especially for wintery salt treated roads around town. 8)

I like the looks of that Roughhouse. If I had any room I might go for one...but as of now with 3 motorbikes, two cars, and a bicycle in the garage I have to pass it by.
I can understand your wanting to keep a nice bike looking that way. My PCX is not in the category "nice looking" however. I have dropped it 3 OR 4 times. The large faring whose name I can't recall is cracked and patched in an unsightly manner....so I have no incentive to be too careful not to get it dirty. Of course, I always have a very strong incentive NOT TO DROP IT AGAIN.

Mine must be running on magic then, still has the factory battery. Nearly 17,000 miles and over 5 years it's still going. Just went for a nice ride the other day, temps down around 20F (that's -6C) and it started right up!

Same here - as posted above, no issues after 4 years with my original battery and the bike is outside all year round so puts up with many months of very cold or sometimes below freezing. Normally would not go much more than a 1-2 weeks in winter without being used, and just over 3 in summer.
That said, some people have posted how their batteries failed within a year or so, so as with anything, some bads ones.
The lithium batteries mentioned seem to hold their capacity, but some reviews said they have small and flimsy metal posts compared to other makes - not saying they are not suitable for use, just what I read.

do you guys have Stop/Start feature in the states? Using that feature on regular basis drastically reduces the life span of the battery. Terminals on the Shorai Battery are same as any other battery, flimsy they're not but i can't say for other brands out there as i never used any others.

No mandatory start / stop in the U. S., so we don't have it (it's really hard on the engine due to no oil pressure during startup causing wear). I'm looking at going lithium for the Fury, but $350...ouch.

Thanks for the topic...found this as far as cold weather:
In cold weather (-4⁰F) the Lithium Pros battery should be the same actual amp-hour size of the lead acid it is replacing. Lithium Pros batteries should not be used for engine starting under -4⁰F.

Followed the link to Shorai, the LiPo is $200 there and 19AH vs. the earthX at $350 and 12.4AH, THANKS GUYS!

The stop start is neither “hard” on batteries or the engine.

Everything is doing what it is designed and manufactured to do.

Stop/start wears the battery which is supplying current while the engine is not generating it; all batteries have a limited amount of charge/discharge ability and this is using it. On the restart there is no oil pressure which contribute greatly to engine wear, unless the laws of physics are somehow suspended.*

The Fury guys advised me to not get a Shorai, they had lots of failures. The earthX has been holding up well, I'll get an aviation grade when the current battery dies. LOL

*When the engine is running the crankshaft and main bearing surfaces are separated by a thin film of oil from the oil pump and hydrodynamic lubrication. When the engine stops the crank settles onto the bearing and the two metal surfaces come into contact. When the engine starts the crankshaft spins with metal-to-metal contact before the two surfaces become separated by the oil film (called the "boundary condition") when most wear takes place. This normally happens around 50,000 times during the life of an engine, but now happens 100 times that amount--you can tell me bearing technology has improved, but you can't tell me it improved 100-fold. Oil technology improved, but it's used under hotter conditions and tighter tolerances, so that comes out even if you change it often enough, and the EPA is forcing manufacturers to stretch that number, somewhat disregarding the outcome.

Wow. We seem to go through a sky falling stage.

Everyone needs to stop thinking and get back on their bikes.

This is true when there is a standard run of the engine without start/stop. The scooter Honda there is a smooth start and no oil film rupture no, just as there is no high current on the battery.
