Went to start my Jota this morning and got just a click from the starter button, checked the battery Voltage and its reading 10.5V,removed the battery from the bike and charged it on my bench ,it quickly got up to over 12V on the charger but as soon as its disconnected it drops down to 10.5v again...looks like a new battery is needed, its a Yuasa 53030 28ah, and its been on the bike for at least the last 3 years...should i stick with the wet type of brick or go for something more expensive like an Odyssey pc680?
Dead battery?

Which bike is it and is the charging system original?
If it's the silver one in your picture, on an OEM system, then a wet cell is best.
I have a Bosch M4F54 in mine, supplied by Tayna.
Order it today and you may well be up and running this weekend.

Thanks, 1977 Jota - it has an Ignitech ignition system and uprated alternator fitted by Keith Nairn.

If it has an Ignitech, it will be fitted with a regulator. In that case you have freedom of choice on batteries. You may, even, wish to fit an Odyssey battery. Though expensive, many owners consider them to be well worth the expense. I'm not sure of the correct model, as they are no use to me, with a voltage wild system on mine.

I have an Od on my Jota...lost track of age, maybe 8-10 years..never needs charging even after long periods of inaction. But battery threads are a lot like oil threads, everyone hss a view...After acid stains from numpty fitting by dealer of wet battery overfilled and without breather some 23 years ago, I see the virtue of non wet batteries

I've been using Motobatt AGM (gel) batteries for years, on my Kawasaki, Guzzi T3, Triumph Thruxton. All requiring good cranking power and, as not all used on a weekly basis, there is a need to hold their charge, which they do. The only thing I would say, is that if you dead flat them by leaving the ignition on (don't ask) it'll kill them. The only one of my bikes that I have to regularly put on charge, is the Thruxton, as that has a factory alarm/immobiliser. The others can be left for months without needing a top up.

I'll second AGM batteries. Yes, a bit more expensive, but in my experience well worth the cost as they last longer (had one last 7 years in the RGS) and there's the plus of no battery box corrosion from off-gassing. I have Decca (East Penn Manufacturing) AGM batteries in all my bikes. They're excellent.
