Mine lasts 2 weeks ish. Has factory Hamilton Palmer alarm.
And occasionally turn ignition on to wind window down for pushing it about etc.
Ended up just getting a batter conditioner. And leaving it plugged in all the time.
Hmm not sure how they'll look just yet but wanted another set of wheels for track something light that can run better tyres on.
The ns2r were really not great on track. Squeling all the time and letting go much sooner than I'd have liked!!!
Anyway..
