Currently, I drive my S2000 at most 4 times a month. I find that I need to jump-start my car now because the battery keeps getting drained by being parked for extended periods.

My brother-in-law suggested I purchase and use a battery disconnect like the one at this link.

I emailed the vendor to see if it will fit our car and safe to use. He advised that I ask the dealer to see if it was OK to use as late model cars sometime require power for the CPU.

So is it safe to use? I'm planning on purchasing a new battery and using this device hoping to prevent the battery from draining completely while it's not being driven.

Thanks!

 

I know it's a little more money but why not pick up a battery tender.

 

What's a battery tender?

 

I don't know but I just bought 2 of them

 

It is safe to disconnect power from the ECU on the AP1s There is no shutdown like I hear of on the new MY07. I disconnect the battery and time i work on the car with no worries. I would go with the quick disconnect thing. Only downside if losing your radio presets etc. and the ECU has to relearn every time so the car may not run its best.

 

Even if you disconnect the battery, it will still get drained if you don't keep it recharged. The best solution is to spend $30 for a battery tender that is basically a slim down version of a charger that continously provide current to the battry to keep it fully charged all the time. You probably will need to get a new battry at this point anyways if you still have th eoriginal battery.

 

Anyone know the difference between the Battery Tender Junior & Plus models? Thanks!

 

I have the Jr. model and it works great. I bought it to use on my scooters, but started using it on my cars as well. I believe the Jr. will only do one battery at a time while the Plus will do multiples. It is the best investment I have made in a while. It has helped prevent me purchasing a new scooter battery- I just hook it up every time I get home and it keeps it working well. You may be able to salvage your old battery, but I would recommend a new one and then use the tender.

 

I'm planning on the Battery Tender to be used solely for the S2000. What's the better buy: JR or Plus? I think it's about a $15 price difference.

Also, just want to confirm, but I would want the version with 12 Volts of output voltage correct because there is a 6 Volts version as well.

Thanks for all the inputs everyone.

 

I need one of these as well
