Last year I have used cheap battery, but when the bike have stand for some wheel example its to weak to start the motor sometimes...

I want to have quality battery and not be worried about the start clutch to wear out faster then it needs to....

Yuasa YTX20H-BS

Is these a good choice ?

18AH is fine also, I see the service manual say 12AH orginal.

I will try to find a without acid, so I can fill it my self, to best quality (if it has been stored for a while at warehouse).

Is there a power source nearby so that a charger can be connected when the motorcycle is not ridden.
Er det en strømkilde i nærheten slik at en lader kan kobles til når motorsykkelen ikke kjøres.

My current battery is a Scorpion AGM & it is now 3 yrs + 3 mos. old. I keep a smart charger connected
whenever the motorcycle is parked in the garage. Ctek US 0.8 smart charger (Sweden).
Mitt nåværende batteri er en Scorpion-generalforsamling, og det er nå 3 år og 3 måneder gammelt.
Jeg holder en smart lader tilkoblet når motorsykkelen står i garasjen. Ctek US 0,8 smartlader (Sverige).

I've been using Yuasa batteries in my 1977 KZ650 since it was new and they work great. One question though - you show a Yuasa YTX20H-BS battery, but my 1977 KZ650 has always used a Yuasa YB10L-A2 battery. Make sure the battery you list is the correct one for your bike because I believe the one you list is the wrong size for the KZ650. The Yuasa YB10L-A2 battery is 5 5⁄16 in. x 3 9⁄16 in. x 5 3⁄4 in., but the Yuasa YTX20H-BS battery is 6 7⁄8 in. x 3 7⁄16 in. x 6 1⁄8 in. Ed

I will double check the measurements to make sure it fits.

I shall try to get highest possible of Ah, as long as it physical fits ?

For normal 12v lead-acid batteries, once it's discharged to 11 volts all the energy has been removed from the battery. It's empty. If it continues to be discharged, it starts to damage the battery.

A battery at 2V is probably permanently damaged. Even if it recovers it will probably have lost capacity and performance.

A battery at 0v is certainly permanently damaged.
