welcome!

sounds normal. what are you getting for mpg's?

 

Normal? What about the simultaneous use heater, wipers and colder climate weather while ICE is off most of the time?

 

i think you're good, but at 10 years old, you have to expect degradation and replacement at some point

 

That's not bad. Depending on conditions, it might be better. Remember that it's not meant to drive very much in EV. Don't force it into EV because it doesn't have the range and you'll have to burn extra gas to charge it back up. The only thing the EV button is really good for is to move the car out of the garage without needing to start the engine and other stuff like that.

Not all the bars represent the same percentage of charge range. IIRC, it's the 5th & 6th that are a bigger range. The others move a little more quickly. I'd be concerned, though if those below #5 dropped quickly while accelerating,

That said, the battery is old enough that it could be getting pretty out of balance. Sounds like a good application for a Prolong grid charger. (Prolong Battery Systems. Extending the life of your hybrid. — Hybrid Automotive) There are lots of threads here about it. It's not a guaranteed cure all, but it's extremely effective in the right situations.

And please disregard the comment on Greenbean batteries. It's a warranty that you'd probably need to use several times. Lots of threads here about that, too. Better options if you do end up needing a replacement HV battery would be new from dealer or a kit from @2k1Toaster. Some hybrid shops also sell salvage batteries that are lightly used, but have been balanced with something like the Prolong system and still have all the original cells. I got one in 2017 for my wife's '07 that was only two years old. Still runs like new.

 

I have a 2014 and it’s normal. If I use the air, heater, or driving the battery bars do go down. I have noticed that they do go down more when I’m in stop and go traffic. I wouldn’t worry unless it doesn’t charge or it takes a long time to charge.

 

I suggest you give Matt a call, discuss, and see if he thinks he should take a look at it. He's in the Weatherford area.

My 2010 does the same thing. If It goes to 4 bars a few seconds later it will drop down to 2 bars. I used Dr. Prius and a Carista module to check the batteries condition. It reported the battery was in good condition at 66 percent capacity. That's at the high range of good so I stopped worrying about it.

 

Please disregard this comment trying to disregard a green bean comment. SMH you guys on here are really on that toasters noodle.
