Welcome to the club 
My ex-Incoe non MF just died , after serving me for like 3 years and 4 months.
Installed on July 2018.
At least yours is a slow death, which means going to die in a month's time.

Using NS70 (or known as 65d26L) on my Exora. Original spec was 55d23L which is abit smaller than Ns70L.

I recommend that you have a battery charger , so that you can charge the battery without starting the engine (which usually further stress the already weak battery) .

Now my new replacement : Recond "Amaron" NS70L battery, comes with 1 year warranty. 

Hi bro, I found the deal at Facebook Marketplace.
He is actually a normal car workshop in PJS 1, Old Klang Road, selling Recond (refurbished) battery but refurbished by another company. So I traded my old Incoe which I traded in, presumably will be also refurbished.

Not that I wanted Amaron but because this is the only he have that suits my car.



BTw I found another one doing refurbished battery. Based in Melaka but claimed can serve nationwide.
