Long lasting and rechargeable, we offer 2 types of batteries. Our newer solar post caps (2015 and later) typically use LiFeP04 3.2V AA solar batteries. The earlier model solar post caps use the NiCd 1.2V rechargeable batteries. To determine the battery required for your specific model of post cap, be sure to check the voltage of the battery currently in your post cap. Since the voltage is different, it is critical that you select the correct battery for your specific cap. Accidentally selecting the wrong voltage battery could destroy the electronics in the cap.
