Watched this thread at the start of the week and very nearly posted something along the lines of "four years and counting without a battery conditioner never mind a charger, two dead regulators and no issues with the original Banner battery; so what's the problem?" I am now really rather glad that I resisted the temptation...on Thursday I went to start it and got the machine gun solenoid routine; it had been sitting for about four weeks so just used a booster to get it going, ran it around to charge it up then did the oil change and such things. Went to go for a run yesterday...almost started without the booster but not quite then after about an hour's driving I stopped for about ten minutes to take some pictures and it refused to start without the booster. Cutting long story short I now have a lithium battery on order that hopefully will be less bothered by being left sitting for weeks on end. I also rather like the lithium battery booster pack I bought a couple of months back that not only starts dead three wheelers but recharges extremely quickly from the 12V socket.
