Here is my current battery problem.

Car is 5 Yr old
Never Changed the 12 V battery
Clipper Creek 10 AMP Charger

One Morning, The car was trying to charge but i keep hearing click sounds and retries again and again until in the Evening i am back from office.

Car 12V battery is dead as the car no longer turns on.

Jump started using another car, RAV4EV turned on Fine. As soon as i disconnected jumper cable. RAV4EV went dead.

Jump started again and let the other car ON for next 15 mins and jumper cables connected. Assuiming RAV4EV 12 V battery will get charged.

RAV4EV didn't shutdown even after removing the jumper cable.

Tried to charge the car again and it keep making clicking sounds and i disconnected the charging cable.

I turned off the RAV4EV and after 30 Mins RAV4EV doesn't even start again.


Is it 12 V battery problem or something else. Please let me know. Based on your suggestions i will have to decide to take the car to PepBoys or Toyota Dealership .

Advanced thanks for the feedback.

It is almost certainly the 12v battery. That the original battery lasted for 5 years is a minor miracle as the RAV is really hard on them. Do NOT reconnect the dead battery to the car any more (and if it's connected, disconnect it). Low voltage situations have been known to cause lockups that require dealer intervention to correct. Get a new battery and install it ASAP. Read further up the thread for specific battery recommendations.

Need to measure the actual 12v battery voltage after you remove the cables. Voltage should rise above 14 volts if the DC/DC converter is working.
Regardless you needed a new 12v battery a year ago.

Yet another GREAT example of why you don’t wait to change the 12volt battery. If you have the original 12 volt battery, CHANGE IT NOW.

Good luck with all the issues caused by not proactively replacing the 12volt battery.
