2008 still has a good hybrid battery; what is the best recommended course of action for when it goes

You started two threads. one saying the battery is good and another saying it is not. you’re at the right place for advice, but consolidate your thoughts into one post! Like i mentioned in your other thread, don’t worry abt your battery. treat it like your other car parts and forget abt it. Other than cleaning your battery cooling fan and parking in shade when possible, there’s nothing else to do. have some $ saved for when you buy a new or refurbished one or replace modules and charge/discharge cycles. enjoy your prius!

 

Battery rebuilding with used cells is obviously a crapshoot like rebuilding anything else with used components used battery cells they have a life cycle how do you know where you are in the batteries life cycle or the cells life cycle?. Essentially you don't by charging and discharging and back and forth with that you can kind of guess by what the numbers do but you're not really sure. What you do know is if you have an original car with the original battery cover and all of this sort of thing is that you might have an original battery and today just do the math that battery is quite old and probably getting close if not past the end of its recommended life cycle so you want to maybe rectify that so you can get back to normal driving as the car was as new. And that may not happen by using old Panasonic cells

 

now is the time to consider a grid charger to restore battery capacity.

when the time comes for a new one, attempts to save money will only cost more in the long run, so it will be a matter of how long you want to keep the car
