Batteries are a law on to themselves. My er6 one failed after 8 months. The cheapo replacement has lasted 6 years. If your bikes charging ok your looking at a duff battery I'm afraid.

Another "Optimate" victim :)  They may be getting better at cycling a battery according to my mate who swallows all the hype that these companies claim about their product, but for me let the battery drop it's voltage naturally and charge it up and run the bike occassionally :good: someone down Liverpool area has my old Yellow Niner and I'll bet the Varta battery is still going strong and it was fitted Sept 2012 and there is a sticker on the battery saying so! :good:

Put a multimeter on your battery when it's running, if it's charging the voltage should be between 13.8volts and 14.4volts

Thats more like a symptom of poor charging on the bike. If the battery takes a charge off the charger enough to start the bike then the alternator/regulator may not be charging it enough on the bike. A volts check with the engine running should tell you what's happening

^This^

 

A knackered  reg/reg pushing too much voltage can knacker a battery pretty quickly, or too producing too little voltage and not charging it.  Easy thing to check so well worth doing before splashing out on a new battery.

 

Personally I have optimate leads on both our bikes but only plug them in for a charge occasionally if they've not ebing used rather than leaving them on all the time.

thanks for all the advice folks will check the charging volts and maybe use optimate a bit less 🤔🤔🤔🤔
