Have not used my bike for a couple of months and the battery was completely flat so looking for a charger any recommendations !

Save your money and buy a new battery - quickest way to kill them is to leave them sat in a discharged state!

Any of the optimate, acumen or Ctek are good. Maplins sell cheap trickle chargers.

To be honest I have one from Aldi and a car battery charger from Ebuyer (<£5) that have charge rates of around 1 amp and both work fine.

Optimate will keep batteries topped up (hence the name) but wont revive a dead battery. Time for a new one.

cheers guy's I did wonder if a new battery was the answer ,the bike is only about 3.5 years old , I guess not using them much dose not help with life expectancy !

It all depends on what battery it is. If it's a good brand like yuasa etc then it should take being stood for a few months. My mate's was stood for 6 and then after a charge of the battery it's holding up fine.

I bought a big battery for the truck off ebay a while back. The guy had bought it cos he thought his car needed one but it turned out to be something else wrong with it so it had never been used. Anyway, it had been left for 6 months and was as flat as a fart. After 48 hours on charge, it showed no sign of life. I gave it another 12 hours and it started to pick up, after another 24 hours it was full of life and I've had no problems with it since - holds a charge really well. There is a lot of difference in quality between various battery manufacturers and a lot of the smaller cheapo batteries are total rubbish. Check the electrolyte level in your battery is over the cells, top up with ionised water and give it a go.

BTW, can you let me know if you want this charger as someone else needs one too

I just bought a new one ,the old one was almost dry ,I did not realise modern batterys needed maintenance these days !
