Charging hybrid battery

After nearly 10 years driving the Gen ll Prius, I must say that I am not coping too well having changed it for the Gen III - often press the 'Start' button instead of 'P' Toyota having changed the layout and too many buttons and options!

Bit disappointed to see the mpg has dropped from my normal 58 - 60 mpg to around 51mpg and wondered if the hybrid battery is charging properly. When braking going downhill, the CHG on the display moves right over to the left, but when just going downhill without braking the CHG barely moves more than a 1/8". Lot of hills where I live. Also, the battery never seems to fully charge, although Dr.Prius indicates it is as good condition and similar to the Gen II.

Any thoughts would be appreciated.

 

The post is about changing from a Gen II to Gen III. Only driving it for about a month. The brakes were in very poor condition, as mentioned in one of my posts. The 60 mpg was the Gen II which I had been driving for almost 10 years. Dropped to nearer 55mpg in Winter. The 50 odd mpg is the Gen III. I never fill the tank, so clearly not 100% accurate. Use is similar and the final question is not applicable.

 

Thanks for your interest. The post was nothing to do with fuel economy and I was just passing on some info. about replacing brake pads. It was also a few weeks back. As for the mileage it is around 63,000.
