I was skeptical about getting this battery at first because I only get half gram carts and it didn't really say whether it only fit full gram carts or what. When it arrived I was very happy with the way that my half gram cart fit because I honestly at first thought it wouldn't. My battery was also delivered only 3 days after I ordered it. I was surprised at how fast it was delivered especially since it was being shipped from Texas and I live in the Midwest. Cart hits crazy good. I love auto draw batteries and this one is great. CCELL batteries are my number one choice and this battery is the best of the best!
