The battery in my car seems to have died, despite charging the car will not start except with jump leads. It is apparent the battery fitted is not the original but a 26Ah off the shelf flooded battery.
What is the specification of the oem battery, how many Ah, crank current etc? What is the alternator able to source to the battery? Who makes it and what would be a suggested better one? Alternatively one with integral LED condition monitor would be great. There's one in my van an Inca 1.9SDi and it really make weekly and pre-journey checks simple.
Would it be a big or complex job to put the vehicle electronics on another smaller battery and keep this topped up with the solar cell I have fitted. I have loads of Yuasa 12V batteries varied 4-10Ah, cable and terminations kicking about. As the car is off road I'm concerned about the self-drain and drain by clock, flashy lights etc and the key coding for the immobiliser getting wiped. I haven't looked at the circuit diagram of the car yet
