Costco also has Interstate 24F with 700 CCA and Rc=130 for $90. I found it by putting a 2012 RAV4 V6 in the battery finder.

On the Interstate battery site, this appears to be M-24FHC since it has the same CCA and Rc ratings. The standard M-24F has 27% less capacity at a Rc=95 minute rating.
The M-27 and M-27F only have Rc=135, so the capacity difference should be minor and the 24F is a drop-in fit as we know.

Either of these seem like a good choice for the RAV4 EV. I personally don't think the Group 27 is a good choice for a typical owner that values an easy installation.

You don't think that with mounting the 27DC battery turned 180 degrees (with the posts towards the front of the vehicle) that the cables would reach?

I stuck a 2008 Tacoma in the Costco search, and got the following 24F battery @ $93.99, but it's still not deep cycle: https://costco.interstatebatteries.com/ ... Country=US

YOUR BATTERY INFORMATION

Item Number: 1131901
Group Size: 27F
Cold Cranking Amps: 710
Cranking Amps: 890
Voltage: 12
(RC) Min @ 25 Amp: 165

It's entirely possible that the cables will reach the front of the battery if you flip it around so that the terminals are on the correct side of the vehicle. I was actually more concerned that the Group 27 battery is 1 1/8 inches longer than the Group 24. I did not look at the battery tray on the RAV4 EV to see how it could be accommodated, but assumed that something would have to be modified. To me, any modification is a big ask for a normal owner. If no modification is necessary, then sure, go for the bigger one. Rc=165 is a significant increase in capacity.

I think I’m going to buy the larger Group 27 battery and see what needs to be modified.

Yes, the Group 24F Interstate battery will just drop in; no modifications required.

I have a new “favorite” 12 volt battery for RAV4 EV:

COSTCO # 850952
$87.99

Built by Interstate
Model 27-DC

...

hmm - I checked for it and could it be the costco #850982?
I plan to try a new 'pure' sine wave converter tomorrow: giandel 1200W, and like the idea of removing the fuse. I bought the HF battery anti-theft contraption, but had difficulty in mounting it.

Presumably the steps would be:
open hood
hook up powered-off inverter (ground and + side on the charger side)
start ev
turn on inverter
pull fuse

suggestions welcome,

Well, my Costco Group 35 Interstate battery pooped out yesterday. It may not have been the battery's fault, as my wife didn't drive it for several days and also left it unplugged "since it was full". Anyway it was down to 7.4V. Pulled it on the spot, and took it over to Costco. It was on the last month of its 42 month free replacement warranty. I figured they would test it and that it would test OK (in which case I was going to replace it anyway), but apparently Costco doesn't bother testing batteries you bring back, they just replace them on your say so. So I got a brand new battery for free.

Probably why their batteries no longer have free replacement warranties, but more normal "limited" warranties.

I did get to do a Tony Test since the car was without a battery for a few hours. I got 128 miles for 87.7%. Not too bad for a nearly 6 YO car. It took it only 5 minutes to charge from a normal charge to an extended charge and the GOM didn't go up even one mile.

42 months on ANY battery in the RAV4 EV is truly "whistling in the cemetery". If you're on Facebook, check out our group at:

Sorry, I don't do Facebook. The company is simply disgusting, I won't participate any more than I can help. So for SoCal how long is your upper limit? 36 months?

Anyone run a lithium drop in replacement?
