New battery 6Ah instead 4Ah

[Mr White]

Hi there, my motorbike came to me with a weak battery.
Lately I had to charge it every couple of days.
I looked at the battery 12v 6ah, and I ordered a replacement 'gel' battery of the same specifications.

Now I've found out that this motorbike comes with 12v 4ah fitted.
Nothing bad should a happened as It was running on 6ah battery for last 3 months.
However as the battery was weak the seller could just put his used battery in it so it wasnt true 6ah.
I should get new battery tomorrow.
Do you guys have any experince with fitting higher capacity batteries to motorbikes?
Did you experince any problems?

You didn't say what bike it's going on.

Just holds more charge.

I suppose the only potential problems are it makes the alternator work a bit harder to keep it topped up or if it's a weedy charging system, that it may be unable to keep it topped up.

Can't really see it causing a major problem to be honest.

I'm guessing at a 4Ah standard battery, it is kick start?

No its Sachs xtc 125cc
no kick start, just a big 125cc bike with tiny battery.

Should be ok. Pretty sure those have a proper charging system.

There is an outside chance it could be a bit sluggish on the starter if you do lots of short runs which don't give it a chance to fully charge but I suspect you'll actually find it will be better than the 4Ah one.

The only other potential issue is if it fits in the battery compartment but if you've ordered the same one as is already in there, no problem.

Its not like I am trying to run 12v in a 6v moped

[hmmmnz]

im surprised it came out with just a 4ah battery, i don't think you'd get too many trys at turning it over with that,
i have a 16ah in my xz400 and a 800ah in my van

I had no problems in using a Honda CBR400 spec battery in my Peugeot Speedfight 100. It was a higher (ah) rated unit, but i chose it as the battery dimensions were the same, except for it being about 3/4" taller than the std battery. I did have to get a longer rubber mounting strap from another bike to secure it, but that was easy to change.
