When shopping for a battery, it is vital to understand the type and size you need for your particular use. For example, the NiMH code listed in the table (6HR61) assumes a cylindrical geometry and would not apply to the pictured NiMH cell. As a result, 6 1.3v 4A batteries would yield a '9v battery' of 7.9, which causes the performance issues that the poster mentioned. The company says that it introduced the PP3 battery in 1956,[9] having been added as an ANSI standard in 1959, currently known as ANSI-1604A.[10]. In non-alkaline batteries, dry elements are used for generating power. The dimensions of a 9v battery are quite simple, they are 4.5cm x 2.7cm x 1.2cm. On the other hand, the non-alkaline batteries will have more discharge time. However, keep in mind that the cost of replacement batteries must be considered when determining which type of detector is more expensive in the long run. $1.90/each.
