My battery is dead.
Stranded at a petrol station today
Is it possible to fit a AGM battery in my Z?
what is de maximum Ah I can fit?

grtz Roger

 

Sure. Any group size 35 battery be it lead-acid or AGM will fit. Physical dimensions are absolute (+/- a few mm for the mounting tabs and terminal height variations but still fall within battery size standard range.)

Just make sure you buy one with adequate/minimum cold cranking amps which is upwards of 600CCA (582 to be exact) but I've seen others in the 550 range work as well. Most wet or AGM "premium" batteries (non-no-name) are in the 600+ range.

 

I run an H6 or Size 48 AGM

 

I'm running a Group 35 AGM Interstate battery from Costco, 650 CCA, works great, fits great. I took the time to thoroughly clean up the positive post clamp when I still ran a traditional flooded as they often get the green crusties on the copper. Simply cleaning up the clamp made a huge difference (metal brushed and soaked in white white vinegar), but ultimately I had to replace the old flooded battery as it had reached the end of the line. AGMs are great, just be careful you don't over-discharge them as that can cause permanent damage. The same is true if you over-charge them. Otherwise they're great, last a long time, no more acid leaks either! (no distilled water maintenance caps, fully sealed units)

Thx guys

I needed a battery quick and bought a normal 65Ah Era battery.
The next one will be an MGA
