Query: Accurate, better than Battery Tester SE

I have a lot of batteries that have been sitting in a drawer and I also use rechargeable batteries for photography and around the house. I needed something to help identify which were ready for recycling/recharging, and which were fully or partially charged. At first I bought the SE Battery Tester also available on Amazon for about $3. However, I found that it wouldn't give reliable readings, so I ordered the Delkins tester. It works much better on both rechargeable and normal batteries. I wanted to write a review so those people looking at the SE Charger don't make the same mistake I did.
