As far as I know topping up will not make any differance.
If  the battery is subject to prolonged  overcharging you could loose some of the Electrolyte.
IIRC the killer for batteries is letting them go too flat/Sulphination over time.

When I was in the car trade brand new cars in the showroom would have batteries go flat leading to early failure within a few weeks or months. Most manufacturers will not cover this under the new car warranty unless it's caused by failure due to a manufacturing fault.

Maintaing the battery voltage is where Smart Chargers really help as they have a Pulse Charge system built in to top up the charge - activated when the terminal voltage falls below a certain limit.

If you have to top up battery does that shorten the battery life my bat is only a year old and I had to top it up yesterday with distilled water they were just above the minimum

No, not normally. But does indicate that it's been charging a little above voltage needed as this will evaporate the water, hence the need to add some, also to keep the specific gravity in range.

The old Honda manuals have a decent section to describe this balance, obviously for plain lead acid type battery originally fitted.

What voltage would you expect when battery is charged and not connected I have 12.5 is this okay

If they generally float above 12.1 and not keep going down over reasonable period of rest, then that indicates decent range.

12.6 ~ 12.9 would likely be registered with  a new battery with good charge, these numbers for conventional type as being typical.

If your one registers 12.5 and stays there with no use, then all appears OK.

You can watch them with digital meter when cranking too, and can go down to 10.8~6 even for healthy battery when under load. Much under that and you'll also hear it turning slowly.

I always fully charged new batteries - what type is it as sealed is a bit vague as a description.
Is it an AGM type or normal Lead/Acid?
Both these types okay with Optimiser including gell type.

It’s a lead/acid sealed for life as I only use the bike at weekends just like to keep battery fully charged thanks

I have my touring bike plugged in all winter purely because of prolonged lay up but this time of year I find even one run a week is enough to keep battery up.

The 2 pin connectors on the Oximizers are rubbish. I’ve had my Fireblade on trickle charge for the last 6 months and didn’t realise there was a bad connection on it so it didn’t maintain the battery.

Now I have a battery that’s dead and won’t charge because the bike alarm has drained it completely.

I’ve re wired the Oximizer with the parts from Amazon below, cable on the left just cut one end off and soldered it the the Oximizer pcb.
Way better connection.

The C-Tek tells you if there is either a connection fault or reverse connection via the LED lights, more LED's  also shows you charging at what stage it is at plus when its on pulse maintainance charge.

Does the Oximiser have a Recondition mode that will bring even the flatest battery to eventually take charge - might take 12 hours but it does work on my C-Tek.

Today I had to remove the battery from my 400 as I could not see the electrolyte level through the white opaque casing without some back lighting.
