Richard, I am with you on this issue. Better to have more and perhaps not use it, than to have less and need more.

I now that the big problem for motorcycle batteries is, because of their smaller size and the need for cranking amps, the lead plates are thinner, which is why they do not last as long

Vibration plays a role in lead acid batter longevity too.

The largest lead acid battery I have seen was a redwood water tank , tar lined, filled with an and water H2S04 solution and had the plates lowered into it by a chainfall above the tank. The plates were serviced/inspected annually for degradation and replaced as necessary. That battery was in use from about 1910 to 1979 and was retired because it was considered to dangerous. There was no vibration associated with that battery and it could have lasted forever. Our 3 wheelers vibrate considerably, possible more than a softly suspended Harley and the idea of using AGM Lithium Ion batteries makes sense.

Had not heard of lead/acid batteries lasting that long but I do know that Nickel Iron ones do without the regular maintenance you mention (shades of Triggers broom ). Their performance is generally poor but robustness, low maintenance and longevity are exceptional due to lack of plate shedding as they use an alkaline electrolyte.

I understand 80 year old versions are still in use and they have a minimum of 10 year warranty from new. Edison patented them in the US and they were used in the first battery electric cars around WW1. The technology is undergoing something of a revival with the current interest in renewable energy given the low cost when spread over their exceptional life.

The reason the redwood tank battery lasted that long ast it was maybe 20’ in diameter and was designed to have every component part serviceable.

The nickle iron batteries are new to me and interesting, except they must be very heavy.

LightSpeed what was the redwood battery used for?
I've had a Varta battery last over 13 years in a vintage car. Not exactly a benign environment with vibrations & no voltage control.

The battery was used in a telephone switching office. The phone system her in the USA operated on DC from the beginning, 96 volts comes to mind, and it operated all the washing machine like motors that turned a long camshaft that controlled the relays that routed the calls.

The tank was open topped and sitting in a room dedicated to that corrosive environment. When I worked for the company they eased large banks of 2 VDC high amperage lead acid cells all daisy chained together.

My 2016 3-wheeler won't turn ov er. I hear thefuel pump, turn signals but no click from thesolenoid.,
Does the 2016 model have an immobilizer?? Where is it located, please. Thanks for any help.

Crank sensor may be
I changed four items on four mtw

Yesterday my tw does not emit the gasoline pump noise when I switch on the ignition, so I look at the fuse and notice that only the plastic of the fuse has melted and not the metal, by moving it a little it works again and m 'notice that the fuse holder has melted also with the damaged connectors, the wires are too short to re-crimp new connectors so I put a new large fuse holder so as not to have any more problems with walbro.

The original fuse holder with the connectors is on sale at (CAR BUILDER SOLUTION).
