This is just a general question, has anybody had any issues with the standard 12v battery not recharging or being discharged quickly. I have just had to replace a 2nd battery on a 66 plate CHR Hybrid. The car had not been started for 4 weeks due to being out of the country and would not start on return, on checking the battery it only had 5.2 v charge left and did not seem to be able to recharge even when the vehicle was started I am just trying to find out if this is a common fault as i will be getting Toyota to find out what is happening to the battery when Co-Vid clears.
