    Hey guys, I bought a 2008 Toyota Prius, and I'm thinking the HV Battery is just about on its last legs. I budgeted for the expense so it's not a big deal as I was expecting it. However, I want your input before I buy one.

    My average MPG has been sitting around 36-42 with it dropping about 10% within the last 3 months

    When I go on break from work I frequently (though not always) will go from 1 bar in the green to 1 bar purple in about 3600 feet (I measured it on google maps). In which case my acceleration from zero is quite pathetic.

    I bought a Prolong Grid Charger, and I'm confident that it's the reason it has lasted so Long.

    Otherwise I think I should replace the battery now before it fails and potentially leaves me stranded.

    Would I be best to get a battery from NewPriusBatteries.com | Home ? I Have the ability to replace it myself so that's not an issue.

    Or would my best bet be to just go to the dealership and spend the extra 1000$ which I would prefer I didn't do.

    Thanks for the Input! Let me know if I left any information out that could help!

    With a Prolong setup another option might be to look at local salvage yard for a late Gen3 (2013 through 2015) and swap all the modules;).

    You’ve got the right equipment, and I bet the salvage yard pack won’t be too pricey :).

    Another option worth considering (y).

    Have you gone to the dealer parts department and found out what their best price is on a battery?
    If you have a few dealers, call around.

    Same number of modules ;).

    All you have to do is remove them from the Gen3 case and put them into your existing Gen2 case:).

    So some assembly required ;).

    Good luck with your decision (y).

    I'd place a preorder for the NewPriusBatteries.com | Home right now.. and then decide later.. they are still at least a month out.. Sell the core batteries that are functional on ebay..
