Lithium battery.

[Kawasaki Jimbo]

I give up trying to maintain the Yuasa (a good make) 8Ah lead-acid battery on my ZX6R. Another one has died within a year. This wasn't a problem when I used the bike almost daily but that has declined for various reasons. As noted in other threads, the 10Ah Yuasa on my alarm-equipped R1 lasts much, much longer yet I can't find any evidence of parasitic drain on the Kawasaki. My garage has no power so I've relied on occasional top-ups using a charger plugged into a portable jump start. I've looked into getting a solar charger for constant maintenance but that doesn't seem practical.

Time to try lithium-ion because they are reputed to last longer when left idle. What brands are you using, and do you use a charger? Would a Turnigy Accucel 6 hobby charger be suitable? Does the bike's charging system remain standard? Thanks.

I'd be looking at why the battery is dying. Probably fucked reg/rec.

Sticking a lithium battery on a system that is overcharging is gonna result in a big ball of flames under your bollocks if you are lucky and an explosion in the same place e if you are unlucky.

If something is draining it slowly you might still need charging every couple of weeks.
Immobilisers and clocks are known issues - or a faulty component leaking power to earth.

When I'm able to use the bike regularly there's no problem, it's storage which kills it. The R1's similar (though slightly larger capacity) battery is far more robust under the same circumstances, despite feeding an alarm too. In use the ZX6R doesn't let me down and the voltage is maintained so I've ruled out the reg/rec. I haven't been able to detect any parasitic drain on the ZX6R, though that seemed the most likely cause. Maybe the smaller 8Ah battery particularly hates the cold? In the absence of an identifiable cause a lithium battery might be a way to circumvent the issue. I know it's a crap approach to a problem but I've run out of ideas.

Surely a simple test is to disconnect the battery entirely if the bike's gonna be laid up more than a few days and see if you have the same problems. Is it just under the seat, nice and easy to get to?

IF you don't need the battery connected when the bike's not in use:

Lead/AGM batteries will last forever if you look after them. A friend has a 2003 954 that’s still on its original battery because it’s on a battery tender in his garage when it’s not being ridden.

As mentioned, lead batteries hate being anything less than 100% charged so if something’s draining it when the bike isn’t used then it’ll kill the battery off in short order. Either find the parasitic drain or put a battery kill switch on if you can’t put an automatic charger on when the bikes sat.

8AH?
Are you sure? that sounds more like a 125 scooter battery to me

If the bikes charging system is ok and no serious battery drain then put your hands in your pocket for a yuasa ytz12s 12v 11ah

Letting a lead acid battery go low for extended intervals before charging encourages sulphation of the electrode oxide.
There are chargers with circuitry to help manage this.
That sort of charger can recover most neglected batteries but poor battery charge management generally scars the performance and reduces the full life potential performance.
If everything on the engine is in good order then a poor battery might not present but first time the engine has a problem (very cold day) then a compromised battery will fail.
Possibly irricoverably then too if the coatings disintegrate from the shock of deep high load discharging during continued cranking.

All batteries should be monitored/maintained if left for a few weeks at a time off charge.
Proper management can save hassle and ££ in the long term.

When I needed a new battery to replace to old one in the KTM enduro I had a good look at what else was available instead of the usual AGM or lead-acid type.As I had heard good things about the lithium-ion items I had a look on the Tayna website and they seemed to be the way to go.It is much lighter but not really that noticeable when on the go as the bike is already light.The power of the battery is not that much different to the previous ones,as is the price.

The good thing about this newer battery is the length of time that I have not been using the bike (for various reasons).The test button shows that even after quite a layoff where the bike has been SORNed,the battery has stayed at full power.
