Canon BP-975 buying Battery for canon cinema cameras and red Komodo

Product Name: Canon BP-975 buying Battery for canon cinema cameras and red Komodo
Canon BP-975 battery. Works but not nearly as much of a charge if new. I used it on a Komodo and would probably guess it's 50% of its original capacity. I used it for low stakes jobs buying or for testing/personal work. I would be hesitant to trust it for critical work (but it would probably be fine, I never had a power failure or any other issue aside from capacity deteriorating). Sold as-is for parts due to the deteriorated condition.
