battery charger Ah vs battery Ah

I have a battery yuasa 12v 8Ah/10HR. In the last 3 monts (winter) was keept in the house but never used it. I want to buy a battery charger and i don't know what to choose 12V but what about Ah? 5A 8A higher or less. Please help.
Thanks

For a small motorcycle battery you want a low current charger and I think from memory you should charge at the 10 hour rate which is 0.8A for an 8Ah battery. Car chargers are unsuitable unless they have a low charge rate switch. I've got a CTEK charger that's supposed to pulse the current to de-sulphate the plates then charge at 0.8A until 14V is reached. It then reduces the output to maintain that Voltage. I think Bike magazine were giving one away if you took out a subsciption recently - godd value as they are about �36.
Hope this helps.

I'd go for a CTEK and avoid optimates, every one of the latter I've had has had problems (over the years I've had 4 of the ******s and the last one is now intermittent).

I'm very satysfied. In winter, when may happen to don't use the bike for 1 month, I leave ever attached the controller (there is an useful connector that is ever attached to battery).

Ciao.

Accumate for me

Accumate best investment I've ever made. Been using it on my bikes and to date not had to change one single battery. It can do both 12 & 6 V batteries. Came up best a couple of years ago in the "Ride" mag test.
It has enough oomph to even charge and maintain my car battery (although it take a long time).
There is also Optimate (also very good) which has more charging stages but strictly motorbike batteries as it has a lower current delivery and 12V only

thank you for your replies. The tehnical informations helped me not to buy a battery-car recharger because they don't have the right Ampere value.
I ordered a saito procharger compact 12V 0,6 A from Louis. I couldn't find one with 0.8A, only higher. I have to wait.
Thanks again

If you have a constant current charger at 0.6A and forget to remove it afer its hours its much worse. Its recommended to use a smart charger like Ctek. By the small one who has a bike symbol on.
