Now nearly four years old and getting little use of late, the battery in my Breva hasn't long to live. Soon after a ride the Voltage drops to just below 12V when it shoul be more like 12.7V or even a little more. Yes, I do use a battery minder quite often, and the Voltage was measured at the battery terminals.

Apart from a replacement Yuasa, what batteries have been found suitable?
 
An Odyssey PC545 slots straight in, although you need to pack out the top a bit so the plastic cover screws down tight.
I just used a bit of polystyrene.
The terminals are reversed too, so the live is next to the left hand frame rail, doesn't get too close to it though and there was plenty of slack in the cables to reverse them.
Mine cost about £45 on e-bay and they live for years, and hold a charge much better than wet cell batteries.

Here's one i found on e-bay, you can get them cheaper!

These batteries are great and if you plan on keeping the bike for a long long time it's probably the last battery you will ever buy. I was told at by the manufacturer at their booth at the motorcycle show that the battery show be charged at a rate of no lower than 3 amper hours. I helped a friend install one in his bike and he let it go dead after a long Chicago winter. The next spring we took it out of his bike and used a car charger to bring it up to full charge, then monitored it for a week and it never lost any of it's charge. Worth the extra money but only if you plan to keep the bike.

Are you sure you got it right? First of all, "rate" would be measured in Ampers. not Amer/hours. Second, I heard that low charge current is better for restoring a discharged battery. Maybe he said "no higher than 3 Amps"?

Good on you for question this. There's a lot of black art when it comes to motorcycle battery care.

My favorite is to trickle charge the battery two or four times daily, one hour total maximum. Never lost a battery yet, despite months of inactivity.

As usual,

YMMV.
 
The makers of the Odyssey battery make it quite clear in their instructions that the charge rate should be no LESS than 2 to 3 amps.
This applies to all batteries made with AGM technology.
For this reason, I use a CTEK 3600 charger, which does everything required.

PS, just looked at the manual which came with mine.
It says that while a M/C battery tender, or low power charger will hold a fully charged battery at full charge, it will not recharge a discharged battery.
 
My recollection is the man at the show said -"no less than 3 amps' which is about what a car charger with a damper cuts back to. He told me that my motorcycle battery chargers really would not charge my battery properly. We used a car charger on my friend's battery
and that was the winter before last. This spring that bike started right up and just returned from a 1700 mile trip.
 
varta YTX20BS £68 from tayna.co.uk. Terminals are correct.Yes thae varta is 2cm longer, you just trim the plastic foot on the holder.
 
I think the carriage charges from Tayna UK to New Zealand might be a touch high Nel.

But I think there is also a Westco battery of the same size, and this is a sealed AGM type. Tayna's website does give all the battery dimentions, which might be useful.
