Replacement battery for my D4

For an urban triangle type use that voltage is pretty normal.

After it was fully charged I removed the earth lead and let it rest for about an hour then reconnected. Started great but then always has and the only change seemed to be date which had gone back a few years.
Maybe a trip to the stealers if the message comes up again.

12.5 v is 90% charged. 12.7 is fully charged.
I believe that if you leave the charger on for too long the cranking battery voltage will eventually exceed that of the auxiliary battery and then the system will start to suck power out of the cranking battery to charge the auxiliary. Sorry, my knowledge is very general but I now disconnect my charger as soon as the cranking battery shows fully charged. So it seems what you are doing is correct. I’d be going back to where you bought it and having it checked out.

It seems that disconnecting the earth etc. have had the desired effect and the warning has now gone. I shall monitor it closely. :)
Thanks for answers all.

Reviving this thread. I'm up for a new battery. Tried to revive it with my Ctek charger but no joy. Not dead yet but getting sluggish. Won't charge above ~12.2v

I've eliminated Odyssey from the options based on bad feedback on here.

Slightly worried about the reliability of the SSB based on a few warranty replacements mentioned on here too

So, here's my list. Varta seem to have a good rep but pretty expensive

5. Delkor LN5 900CCA 95Ah ?kg

Thoughts from the brains trust please

I've been very happy with the SSB - has outlasted the Varta :)

Thanks veebs, how long have you had the SSB ?

Couple years - and in fairness the Varta likely had a fault, however never seemed to have the same punch the SSB has to this day.

Also have the SSB aux battery with traxide, likely helping things. Previously this was a yellow top

Have you priced a YUASA? Their batteries in my m/bikes and ATV's have lasted many years. I intend most likely putting one in the D4 very soon.

Very different beasts.

Almost no parasitic draw and very little electronics in bike and ATV

On the later electronic vehicles - big CCA and big RC along with quick charge take up are the important part.
