    Hi all, I am dealing with a possible failure of my 2005 Gen 2 hybrid battery. The car has 190,000 miles on it. I replaced the hybrid battery in late 2017 with a reconditioned 2013 battery from Electron Automotive in Anaheim, and it has done very well until now.

    I'm not going to do the install myself, so that should eliminate a lot of options. I'm located in Los Angeles.

    OPTIONS:
    1. Going back to Electron. I am not unhappy with the life of my current battery from them, which lasted 8 years. Electron now sells these brand new CYLINDRICAL CELL BATTERIES, which they apparently make themselves, and which run around $2700. Electron claims they are at least as good as OEM, if not better. Any thoughts on this?

    2. Could get a Toyota OEM battery installed.

    3. Get someone who can repair/replace bad cells in my current battery? (I'm not too inclined to do this).

    4. Other suggestions welcome.

    I vote for option #2.
