Sudden drop in ev range during last 20 miles.

[neal adkins]

Range falls quickly on my 2018 clarity after driving about 28 miles. The last 20 miles displayed may actually drop to actually 11 miles or so. I had replaced my 12v battery about 6 months ago but decided to check it. hooked up my charger and it was at 11 volts. It took about 35 minutes to charge up on a 30 amp charger. My next move is to get 12v battery tested. Any thoughts would be appreciated.

typical lead acid batteries are a 3-6 year service life on average. you very well may be near end of life on it if its from 2017 (probably made well before your model year installed it)
