Was using Century Marathoner NS60 on my waja 1.8 and only lasted just above 1 year...
Now on Amaron N70 from bateriku.Voltage on everything off is 14.4v.
Voltage during idle,headlamp on,aircond on is 14.3v. Impressive really.was expecting more drop even my alternator is new. The tech is a very2 nice guy. There was miscommunication between him and his hq as i request credit card as payment method but the tech was not informed. This was realize after he install the battery,since i have no cash he trust me to bank in the cash the next day.Speechless....
Anyway so far, the best battery that have served my waja is the Yuasa EcoCR. Too early to comment abt Amaron but inital impression is good.The Yuasa one was surviving even with problematic starter. In my case when i try to start,everything went dead or start flickering.
