If your 12 volt battery is over 3 years old, and it's the original crappy Toyota battery, REPLACE IT NOW before you have problems.

Rav4 EV 12 volt Battery recommendations:

https://m.pepboys.com/search/?term=bosch+24f+60ah+agm

I recommend the Bosch or Exide battery with the following specs for around $150-$180:

1) AGM (not flooded acid cells like the original)

2) Group 24F size

3) 60 amp/hour rating


Here are the specific models I recommend:


Bosch S6508B S6 Flat Plate AGM

There is also a Exide battery that is identical, except for superficial color and markings, but normally more expensive.

Exide Edge FP-AGM24F Flat Plate AGM Sealed Automotive Battery

I have noticed that if I stick to my 22 mile round trip commute the GOM seems to sag over time.
Then I go on a 110 mile drive and the range pops back up. Whatever.

Anyone ever see Turtle with 5 miles showing on the DTE?
I did last night cruising home at 62 mph on the freeway. Was able to take my exit (1/2 mile) but not climb the hill to my home.
Coasted to the local shopping center and was able to plug in. Main power was off for a 1/4 mile as I rolled in.

Previously if the DTE said 5 miles I had a least 5 miles and probably 7 or 8.
Is this temperature related? Been cool lately but not cold.
Or is the battery just getting old?
Something else?

Yes, I've had TURTLE with miles showing (and one fuel bar), and my car was relatively new at the time. The first time I got towed for no power, and the conditions were snow, cold, up a very steep hill.

I think there is at least one who had two fuel bars showing with TURTLE!!!

When is the last time you did a full "extended" charge and let the pack sit for about 8 hours?

Never. Although most Fridays get full charge and a 2 hour wait before I head home.
Every couple weekends the same thing to charge overnight and it sits for a few hours as the timer is always early.
