So my 2007 prius was running rough so I changed out the spark plugs, coil packs, and fuel injectors. It is running better but now it wont charge my main hybrid battery, and it only runs when the cars generator is running. It wont accelerate and when you do it will only go really slow. It takes forever to get up to speed. It has been sitting for a few months but when it was running good the hybrid battery charged. Now it wont. In the spring I replaced three bad cells in the hybrid battery and it was great. So I could use some help. So I want to start with the hybrid battery. What could cause it to not charge? The smaller battery which starts the car is new and tests out fine.] Any help would be appriciated.
