The factory battery has finally died on my 2003 Challenger LS. I would like to replace it with a heavier duty one.

Does anyone have any suggestions or experiences with installing a larger battery to replace the standard one?

Fit the biggest AGM you can get in the slot.

Then you can run a fridge for days without a dual setup being required.

I have a 100AH, 1000cca unit in the Jackaroo and its excellent.

For a replacement starting battery at a reasonable price, I recommend the Exide Extreme.

I do not support using a single battery in any vehicle to run accessories such as a fridge. That is just asking for trouble unless you include an under voltage cutout device and even then I would be extremely nervous venturing into remote areas with this setup.

Hi Lockey

My factory battery died after 2 years and I replaced it with an Centruy/Yuasa Overlander 700 - it was basically the largest "normal" battery I could fit in the tray. Four years later, it is still going strong. I generally do not run the fridge off it - except when driving or for a few hours or so when away from camp fishing etc. I haveinadvertently left the fidge plugged into the car overnight rather than the AGM "battery in a box" I carry and it started no problems teh next morning. I too would not recommend doing this as a regular thing, as it is asking for trouble. Itut it is nice to know that it can be done if needed (or I forget).

I have a Century N70 in my Challenger, the N70 will fit no problems but would reccomend an Exide Extrene. Doesn't take much to kick over the V6 in them but with a N70 you will have plenty in reserve.

Thanks to all that answered.

I went for the Centruy/Yuasa Overlander 700. I have another deep cycle for running frdge etc, but wanted a good quality main battery.
