Replacing battery

[dreamcruiser80]

I have 100 and was told that my battery is only turning 584 CCA when it should be 710 CCA. They said I should charge it or replace the battery itself. Questions with this:
1. What would you all recommend. I live in Windsor, Ontario so it can get cold here. Replace or recharge?
2. More importantly, I have heard that replacing the battery affects the nav unit (black screen and no external power source issue). Any experience with this? Any words of wisdom if I do replace the battery? I don't want to lose my nav unit because I changed the battery.
Thanks for the help!

Not sure what year you have

I am confused though and need some clarification.
- are you measuring actual output in the vehicle or is this a test out of the vehicle?
- If the Battery isn't fully charged, either your not driving much, the battery is defective or your charging system has issues
- I have changed batteries with no issues relative to the Nav system, not sure what issues your talking about here.

I run to Sears Platinum which is the same as an Odyssey. It's expensive, but worth it for my needs. A less expensive battery would likely work for you as well

Just replaced a 7 year old Interstate lead-acid. Very happy with the Sears Platinum but 7 years is damn good battery life for a $65 battery.

at 7 years the platinum still has 3 years warranty left... just sayin. of course its pro-rated warranty for years 7-10(?), so there would still be some cash outlay.

Plus it is over $200 (just put one in myself) and there is some cash outlay there too. But I did get a new to me pneumatic driver that was left under the hood. Looks to have been made by Snap-On. Nice trade, I think.
