KevR Posted March 27, 2023 Share Posted March 27, 2023 There has been a lot of chats with regards of 12 volt battery failures on HEV/PHEV vehicles. A lot of the discussion has been around the overcharging of the battery, leading to the failure. I have 2022 Ford Escape SE PHEV. I have a Battery Monitor hooked up directly to the battery and when charging the charging voltage is 15.1 volts. Is this to high to charge a the Lead-acid battery? In the old days of alternators the voltage regulator was approx. 14.7 volts. Quote Link to comment Share on other sites More sharing options...
