Very good battery.
Great long lasting battery, I use two of these in my metal detector and have found that they last a long time before my 'Low battery' warning light comes on. I used to have to carry a spare set of my previous brand with me when I was metal detecting but since I changed to Philips Super Heavy Duty Battery 6F22L2D 9V Zinc Carbon I do not have to do this anymore.
