Have an off road modded rust free D2 that I would like to keep on the road.
It stat outside for the winter months.
The battery is 3 years old.

Trying to jump the car it beeps consrtantly and it wont jump start .
Suggestions - or is this just a get a new battery moment.

Thanks.

 

Might need a new battery. Did you try slow charging it with a battery charger? Sometimes, just jumping isn't enough...if the battery has been completely dead for a while.

 

Before getting a new battery you could first try charging it up with a trickle charger or something similar. I find I have to throw my battery on there every couple months just to top it up with how often it gets driven.

 

Perfect! Thank you.
This is what I suspected.

Thanks!

 

If a really dead battery is your issue, I would disconnect it (maybe just from the negative terminal) and try jumping again. If it still doesn’t work, I’d suspect something more like an immobilized issue.
