Thank you for viewing. Canon Compact Battery Pack CP-E4, dedicated case, 8 Eneloop batteries, charger included, no leakage. There is some deterioration in the spacer-like parts that hold the AA batteries in place. Some parts are missing, but the AA batteries are held in place, and I experienced no contact problems during my use. Please be sure to check and approve the images. I cannot guarantee future electrical conductivity. Please understand. There is no leakage. I was unable to photograph the inside of the main unit, so there are no photos, but I did not see any leakage during my visual inspection. Other than that, there is little dirt, and you will likely not feel it is unsanitary. No damage was found to the main unit case. I will include 8 Eneloop batteries and the BQ-CC2 charger. Everything in the photos is included. I am sorry, but I cannot accommodate returns, refunds, repairs, or exchanges. Please purchase only if you agree. Also, please agree not to hold me liable for any disadvantages resulting from the use of this product. In addition, I believe that the relevant parts could be purchased new at a mass retailer. Thank you for your consideration.
