    At last a battery for my AVO8 meters! Fitted and now they work well. Top chaps.

  3. By Antony Abadjian Verified Buyer on

    The battery was slightly thicker than the original part. I had to widen the space in my meter to make it fit as I could not find this battery anywhere else. It works OK now.

    Surprised to find these available so bought one for a friend too.

  5. By Roy Verified Buyer on

    Rated at 4 stars because the battery which looks identical to the original has just been fitted. I am now waiting to see how long it lasts.

    An ‘obsolete’ part supplied promptly and at reasonable cost. It has returned my AVO model 8 to full operational status.
