My battery has had it but it's only a little older than a year. It's also kept linked up to a ctek when not in use. I bought it from a Honda dealer but it's not Honda-branded, it's a Rob Hunter one.

Just tried to call the dealer I bought it from but they're closed for a couple of weeks.

Any chance it'll still be guaranteed?

What do people do with them to ruin them so quickly?
The one on my FireBlade is over 10years old.


Edit to clarify: not aimed at the OP, just saying!!!

It woukd have lasted longer if you hadnt of left it hooked up to a charger 24/7.

Bring them into the house, charge every few months and they last years..

There are typically 3 (sometimes 4) charge stages - constant current, topping and float.
I would have thought a Ctec would have these three stages so should be safe to be left connected indefinitely.

Your problem is Rob Hunter batteries are crap, I think they have a 1 year warranty but do not expect them to last much over that.

I think that's true for trickle chargers, which constantly send a small charge to the battery 24/7. But cteks (and other intelligent chargers) monitor the battery and only send a charge when it's needed. They're designed to be plugged-in long periods.

Yes, I think I'll insist on a decent brand next time. Are Yuasa the best?

I use either Yuasa or Varta depending on who is doing a deal at the time and my oldest Yuasa is coming up for its 7th birthday with just a weekly top up charge.

I would just leave it hooked up to my CTEK permanently but my bike count out numbers my chargers so I have to rotate them around a bit.

Honestly, I think the quality of modern batteries is crap. My dad bought a brand new Yuasa for his SV650 a couple of years back and it was dead within 9 months, despite being on a maintenance charger pretty regularly when it wasn't being used. I dug out an old battery from my RSV (I think it was a Varta) which was covered in crap in the back of the garage slotted it into the SV and it fired up straight away and has been perfect ever since.

I have found a lot depends on how the battery is prepared before first use, for example putting the acid in, waiting an hour then fully charging it up before fitting in the bike generally makes batteries last longer.

But as I said earlier, the cheap batteries are a false economy, one of my bikes has the battery mounted vertically (as in the positive terminal is above the negative) and the new Rob Hunter it came from the dealer with did not even last the week before one of the cells died.

I know the chargers are designed to plugged in for long periods, I have one, but from what im hearing and seeing, despite the charger manufacturers claims, the batteries themselves are not taking too kindly too it...and as I say, if STORED correctly (ie in the warmth of your house) they will go months without needing a charge.
