Thanks for the tip.
I have been slightly concerned about my DMS Red 750 for a while.
I have been regularly topping it up with an Optimate, but the battery is original; so that is 10 years old and 30,000+ miles.
Also, and for those not familiar with this set-up, it is a small 28Ah battery, and I find it amazing that it has lasted this long.
So I have have just used your link and ordered through Amazon.
