The VZ800 I bought recently had a new battery fitted a month before I bought it, the previous owner had not used the bike since fitting and the battery was flat when I went to collect.
I put a Multimeter across it to ensure it was being charged by the bike and all was well, so we bumped the bike and I rode home without incident with a couple of stops en-route. After a couple of days the battery was flat, I did the usual checks to make sure there wasn't excessive current being drawn whilst the bike was idle and all was well.
Stuck the battery on the optimiser for 24hrs, checked the voltage then fitted to the bike. Turned on the lights and Indicators (no engine) and watched the battery go flat in less than two minutes..
Anyway, the battery was under warranty so I took it back to where it was bought, JTs Motorcycles in Swansea. Some arrogant idiot in their Workshop put his own tester across the battery and in four seconds said "Nuthin' wrong with it mate" Keeping calm I explained the tests I had carried out and told him the battery wasn't holding a charge. So another good three second test with his rusty box he called a tester and same conclusion.
I was getting irate by now particularly when his technical explanantion was that the battery wasn't a Car Battery and therefore couldn't be expected to power the lights with the engine off
I suggested that a battery rated at least 10ah should comfortably run the lamps in that bike for more than two minutes. They were having none of it so I was left with two choices, punch him or tell him to stick the battery up his arse.
I told him to stick it....
After going round the corner to MandP and buying a new battery
charging it, and fitting it to the bike funnily enough all the problems had gone.
So I phoned the Manager at JTs and very calmly and rationally outlined the events that had happened, what does she do? gets the same arrogant tosser to phone me back for another row. Despite me telling him that a new battery was working fine and holding a charge he still insisted there was nothing wrong with the one I returned.
Not worth getting locked up for but bloody tempting. Keep away from these know nothing tossers.
