#21: I do that too.  No problems at all.

So the CTek seems totally happy with the battery now, it's made it into the green on the 7 or so lights on top of the charger.  The battery voltage seems stable too for instance I left full beam on for 5 mins, it didn't cause a significant change in voltage.

I've not had chance to get some distilled water due to work etc but will take a look at this weekend.

Topping up as recommended above. I suggest wearing eye protection and using a plastic pipette. And I find that a head torch makes it easier to see what's happening.

That's interesting,,, are you now considering using it away from home?

Voltages of batteries that aren't under load can be misleading. Dedicated load testing equipment is common in the trade. The best DIY test is measuring the minimum battery voltage when cranking the starter.

How about checking the levels, topping up if needed, leaving it overnight on the smart conditioning charger and then running that test... or the full house:

Battery voltage:
• At rest
• Minimum during cranking
• At 3,000 rpm.

Pleased to hear you may have recovered the battery.

Indeed it is -- what you might call the acid test.

No I won't be using it.  I've a new Banner sat on the worktop ready to go in.  It's more for interest, so I might test it this weekend locally while having the booster in the boot.  Long term the banner is destined to run a raspberry Pi nothing more.

Thanks

PS: On the topic of resurrections... the Raspberry Pi thread.

Crossword anticipation?  : - )

Back from a morning outing with the wife.  Went to Castletown from Onchan for a coffee and shop, then back via a trading estate, ~30miles total.  Also got fuel before hand.  I think a total of 8 starts, including some additional test starts.  It never hesitated.  Plugged it back into the CTeK and i'ts gone to STEP 4 ABSORPTION: Charging with declining current to maximize up to 100% battery capacity, which pretty normal.

So while I agree, better to be safe than sorry and replace, I don't think the battery is in bad condition.

#30:  Promising. 

Out of interest, what CTEK model do you have?
