He was going to give his wife a replacement remote cause her battery died, using the S to transport. The relevant part was he saw no lights flickering from the jump starting. The battery in the remote was a side note.

 

Dude, you need a battery tender. Lead acid batteries hate being depleted. Shortens life dramatically.

You'll end up saving money, and hassle of having to jump (and then potentially get stranded if battery doesn't charge up enough before you stop (and don't stall it either!), or when battery eventually won't take a charge anymore).

 

No, she had borrowed the Boxster to get to the office, and her Porsche fob had an 8 year old battery in it and that died, so I had little choice but to fire up the S2000 to take my fob to her so she and the Boxster could get home. And just a couple of days after the S2000 battery had died. Sheesh.

 

Gotcha.

I have one, sadly the car is parked on the driveway so it's not practical to have it permanently connected. Using a solar panel now which provides enough juice to keep the battery honest with the alarm draw.

When I move house it'll certainly be in a garage and hooked up!

 

I have one of those on my winter beater. Keeps it charged the other 3 seasons. Works great!

Suction cupped to windshield, so still gets sun with windshield sun blocker I use in place.

It keeps battery topped up. Though no alarm making constant draw. But if the panel you use can supply more current than your draw, should be fine.

To measure your draw, set your meter to DC current. Remove one of the battery cables, and put meter between cable and empty battery post. One meter lead to empty post, one to loose cable. Make sure alarm is on. Measure current.

Engine is off!

Now you can compare draw to what solar panel can supply.

 

Had to wait a week and pay for diagnostic services, but everything checks out today so she can resume driving the S2000. Meanwhile she has been borrowing the Boxster, the poor girl.

 

This works very well for that


The battery clamp cable is the short part, so you can have that hanging out from under the hood with the hood closed and just disconnect the tender there if you need to move the car around.
