Well the winter is coming so I guess the battery suppliers are all smiling :blonde:

Just came back last week from a trip, and the next day when attempted to start the vehicle, it was dead. I did a quick charge (4 hrs) and later it was fine. But the following morning once again dead... Thus I guess I am in for the 3 yearly battery replacement.

I have a 639 battery currently installed,

but the Battery Center website recommends:

What I the largest battery that can be installed, getting some spare capacity for the weekends?

Any recommendations or advice will be appreciated.

Thanks

Those + and - pins must be on the other side of the battery :oldtimer:

Thanks guys,

Did any of you upsize? If yes to what did you upsize to? (No mods please, just swap for larger/higher capacity battery )

I have this battery - probably about the biggest that fits into the space - 2,5 years and going strong.
Make some proper heavy duty terminal connectors for yourself as well...

Thanks David and Christo,

I could not obtain any of these "exotics" in the bush and had the following choices:
Make Model Cn 20 hr Ah Is Hold Down L W H Price
Dixon 638 60 280 B0 240 172 220 R 715,92
Dixon 646 60 270 B3 240 175 190 R 747,84
FNB 639H 60 285 B0 241 173 215 R 750,00


But in reality because of the "hold down" and polarity, I only had a single choice. Life is much simpler in the bush as it limits your choices....

During the replacement I found significant airflow space between the battery and the plastic cover - I assume this was all used for the VARTA - it really looks like a massive battery!

If I compare the physical size and the electrical the Varta is in a different league! :woo:

Is my assumption right that it will equate to 5 tanks of petrol :lol: ? For future reference, where would you purchase one and what guarantee does it have?
