The CCA rating of a battery is not so important, it's the capacity in Amp Hours which matters most.

I think the importance of CCA depends on your vehicle. For instance a diesel engine will require a much higher CCA rating than that of a 1.0 petrol engine, especially when cold.

But the battery fitted to a diesel will also have a much higher capacity.

Oh no has it got modified electrics?

The standard fusebox is/was under the right side panel, 6 fuses, torpedo type, 1 - 6 top to bottom, all 16A, regardless what was connected to them or even if anything was connected. On the Spada, the bottom one, number 6, was for the clock, AND, indicators, because the Spada (and LM2 AFAIK) also had a hazard flasher switch, and so to enable you to have hazards flashing while ignition is off (and key taken out), they made the indicator circuit permanently live by powering it via fuse #6.

It also meant any passing mischevious small boys could turn your indicator switch on while it was parked and flatten the battery if you were gone long enough ...

I agree the diesel will have.

I think capacity is important as a higher AH rating means you can sit longer with the ancillaries on without the engine running, and it has a longer resistance to the natural drain on the battery when not in use.

However, I believe CCA is just as important as its the amount of current a battery can provide to start your vehicle. CCA is what a battery can provide for 30 seconds at -17.8°C without dropping below 7.2v.

With standard LA starting batteries the CCA figure will go up with capacity. As has been demonstrated many times a 30 AH lawnmower battery will start a Guzzi with no problem. All batteries lose capacity over time, so if you start with a big one it will still be working fine after some years. The new breed of AGM batteries have a much smaller capacity but a higher CCA figure for their size. This drops as the battery ages and loses some of it's original small capacity.
This is why a standard large LA battery will generally last much longer.
It's also more a question of how long a battery can be left with a parasytic drain such as a clock or an ECU. before it discharges to the point of no start.

That's cheap ! Might try it in my SP. the Tayna recommended one (Exide I think) is twice the price

Hi I had missed this...

Yes, all the cables were redone new, and the fuse box was replaced with another with the "blade" fuses. Honestly I much prefer the blade fuses, but I had not realised that.. there are less fuses!

Brian, agreeing with everthing you said but additionally not all batteries are made equal.  The standard Yuasa LA battery for my 1200 is 19Ah and produces 270 CCA, however manufacture an alternative19Ah battery in their American factory which produces 310 CCA - that may be battery myself and Guzzi1000SE will choose.

America has a history of needing high CCA batteries, to start their big V8s and V twins.  In conversation a Harley dealer mentioned they have to throw away most of the batteries on traded-in Harleys since their owners invariably fit the cheapest battery but to start reliably those big V twins need a high quality and high CCA battery.

Ampac Lawn battery 32/330. The battered unit in my 1100i is at least 3 years old, dont know how long the PO had it, I suspect at least as long. Always recovers following discharge.

Has anyone tried/found a lithium ion battery that works on the old Gucci’s. In my case a V35II. The Motobatt is a block 😆

If you read the info Tayna Batteries supply on their website the basis of it

A charging system designed for lead acid "wet" battery will only charge some AGM batteries but not all. 

Vey ew charging systems designed for a wet battery will charge correctly the Lithium ion ones. 

Incorrect charging can result in damage to the vehicle electrics and even in extreme cases fire. 

I can guarantee there will be someone who has used a Li battery and it works fine but the info is there.

I wouldn't think of a Lithium battery.
The charging system is not suitable.
The capacity of the battery is normally less than half that of a Lead Acid, so will discharge quicker if any residual load is left on it when not in use, like a clock.
The weight saving?? A few pounds compared to the weight of the bike plus rider and luggage, minimal difference if any at all.
Fire risk if things are not set up correctly too.

The best battery for the V35 would be a standard Lead Acid, as in the lawnmower one mentioned above. They last far longer than the AGM type, and will recover from deep discharge, where the AGM type rarely do.
Look at the Tayna website for the options. Just measure the dimentions of the battery tray and height, then get the largest capacity (in Amp Hours) that will fit. Also check the terminal positions for easier fitting.

Brian.
