Re: 6 volt battery question
The battery on the /2 is there strictly to provide power for the lights when the engine revs are low enough that the generator is not outputting enough. Once running down the road, the generator takes over. With proper care, a lead-acid battery should last a long time.
Can't say as I've heard people consider using a lithium ion battery. I don't know how compatible the charging profile of the bike is with what the battery needs.

Re: 6 volt battery question
I suspect that the battery is much smaller. What have you done to get it to fit on the battery tray and look decent?

Re: 6 volt battery question
One of the advantage of lithium is its great crank power, useless on our bikes.
A gel type battery for alarm system will last for years, will never leak, will accept deep discharge, will keep its charge during Winter, is less affected by charging voltage variation from our old type regulator (electronic ones do a better job) and costs nothing. I bought mine on Amazon for my /2 and my Honda CT110 (both are 6 volts) and despite being neglicted for a while, never failed.

Re: 6 volt battery question
I have been using a 6 volt Shorai lithium ion battery in my 1961 R 69S for 2 years with no problems . It is very small and it fits inside a regular lead acid battery case .I only ride during daylight hours and I have never needed to charge it up . I recently bought a Shorai charger with a 6 volt lead for it . I hooked it up , it has a special charging port and it was fully charged in about 10 minutes . The Charger and 6 volt lead was about $ A 177.00 including shipping . If you go this way in Australia there is not a lot of choice buying 6 volt lithium ion batteries .i have several 12 volt lithium ion batteries in my race bikes . Battery chargers for 12 volt lithium ion batteries are a lot cheaper .It would appear that with the amount of riding I do the battery is being charged up enough . I ride about 200 miles a month . Hope this is of some help .

If you have a motorbike with an electric starter, things are of course completely different: a lithium batt can be extremely compact and powerful to start big engines. The expected life really depends of input voltage and temperature.
