Hello,

I tested my 12V battery today and attaching the results. can anyone please see how my battery health looks and does it need replacement. i do not have any issues so far but just wanted to check the health of it.

Attaching 3 pics.. the one at 9.05 was taken at cold start without accessories on.
other two pics were taken after 20 min , about 6 miles drive. with and without accessories ON.

It's below acceptable threshold.

thanks for the reply, should i change it soon or can i live with it for a while?

Do you like being stranded somewhere unpleasant middle of the winter? Do you feel lucky?

Curious! How old is it and what brand? it appears to be taking a charge but not holding it. Needs to be replaced soon!

car it self is 07 HHY, i think the battery is 3 years old, not sure about the brand, i will check and update the thread.

not that i want to be stranded somewhere, i don't use this vehicle for long commutes. i drive it 6 miles to office and back everyday.

Yeah.... It should be at least 12.6-12.8 volts. You are taking a gamble every time you start the car

That's the thing, your driving it Everyday, shouldn't drop that much overnight!
I gave up on batteries years ago, now I buy a decent but resonable battery and swap in a new one every 2 to 2 1/2 years regardless.
Consider it preventive maintenance, prevents me from having to walk!

Thanks, does Costco Interstate batteries work or these hybrids need special batteries?

11.7 id threshold voltage for those batteries. OP's is below. It may cause no start issue. Safer to replace than sorry.
Though in TCH forum, gives you ideas on feasible battery options

12v ALTERNATIVE

Credit goes to a CD poster howardc64 Looks like group 24 batteries are a perfect fit. Got one from Pep Boys (Bosch AGM 24) that measured 10" x 6.5" x 8" so identical to the Panasonic. The +- posts are in the exact same location as the Panasonic (group 24F (I guess F=flipped?) has the +-...

Hybrids need AGM battery. Marine batteries work well. You need capacity, not cranking.

OP, short commute is the problem.
12V is charged off hybrid battery. With such short commute, you barely have enough time to charge hybrid one. Especially winter time. ECM prioritizes hybrid battery state of charge over 12V.
