My car has a ham radio that is relay controlled from the accessory switch. No power hooked up equals no draw. That does not stop the mechanic from blaming the radio for the draw down of my second leaf. I took the easy out and traded it in on my B. I am so happy!

In reality they are just parts changers and there is not an error code shown on their notebook they are lost! Real mechanics that really understand are rare but they do exist, just not at most dealers.

A distressing situation. This brings up the subject of proper long term storage of the RAV4. Later this year, I will be away for 3-4 weeks and the RAV will sit in my garage for that time. Should I:
1. Do nothing - It has survived 2 week absences in the past with no trouble
2. Hook up a float charger to the 12V battery (a new Exide 24F AGM flat plate that I just installed last week)
3. Plug it in to my Leviton charger

My Volt will be similarly abandoned, but it will be at an airport parking structure so I will have little control over it.

BTW, Costco has Bridgestone tires on sale with a total of $130 in rebates on a set of four. You have to be an Executive member, order online (and ship to your nearby store for free) and use promo code: TIRES60C. The offer is online only, you can't get it at the store. I got a set of the Dueler Ecopia's for $534 complete including tax and installation. I will probably have to pay $12 at the store for the TPMS.

Definitely #2. A 12V battery maintainer/tender plugged into the wall is the best thing for a RAV4 EV that will be sitting in private garage. Alternatively, you could just disconnect the 12V battery.

Do not charge the car before storing it unless it is at a low SOC and do not connect the J1772 charging station.

I recently left my car for 9 days. For that period of time you don't really need to do anything, but I put it on a 12V tender and left the traction battery at 12 bars.

Deltran is "the" original "battery tender".

http://www.batterytender.com/Chargers/


This is the one that I recommend for wet cell / AGM batteries:

I also recommend this pigtail, so that you can easily plug in your battery tender (the unit I recommend above comes with this):

http://www.batterytender.com/Accessorie ... rness.html


They also have one that is optimized for GEL batteries (your Bosch battery is an AGM), so don't confuse the two.

Absorbed Glass Mat & Gel: what's the difference?

Gel Batteries

Gel batteries contain a gelled electrolyte which is "Thixotropic". This Thixotropic gelled electrolyte contains sulfuric acid, fumed silica, pure demineralized and deionized water, and a phosphoric acid. The electrolyte in Gel batteries does not flow like a normal liquid; it has the consistency and look of petroleum jelly.

Absorbed Glass Mat Batteries

In AGM batteries, the liquid electrolyte contains high purity sulfuric acid and totally demineralized, deionized water (no phosphoric acid). This electrolyte is trapped in sponge-like glass mat separators.

Thanks Tony. Unfortunately the people in Sacramento are wiser than us :lol: and wont allow that model to be sold in
California. The replacement according to Amazon is : Battery Tender 022-0185G-dl-wh Black 12 Volt 1.25 Amp Plus Battery Charger/Maintainer

Is that also a recommended unit?

I don't know about the other one. I personally have the original.

$200 rescued my car from Carson today. No improvement with the Toyota battery and letting Carson play with it for a week.

Failed to charge at three different stations. Car seems to fail to recognize the main battery is 75% as it intermittently shows LO and says plug in immediately that of course fails.
After sitting a couple hours Ready mode comes up and I get home. Not sure when it will get it's next ride on a tow truck but it cannot be long.

I really think Carson has the most experience with the rav4ev (based on numbers sold)
Their behavaviour really surprises me.
Please keep us posted
Sorry you have to go through this

Carlsbad Toyota in North San Diego County has quite a bit of experience with these.
