PP9 batteries are often used in large torches, radios or bike lights. They use the same dot and snap connection that you find on smaller PP3 batteries (smoke alarm batteries).
These batteries are 81 x 66 x 52 mm and the PP9 batteries we stock are only from high quality manufacturers such as GP Batteries.
With these specialist size batteries it can sometimes be difficult to find the right one you need, especially due to the many names they go by. If you need any help identifying the correct battery, please view our battery cross reference charts or get in touch for more information.
