Most solar-powered products come complete with a rechargeable battery, so you can leave your garden lights to their own devices, for the battery to be charged & recharged by the sun’s energy. However, over time, the solar battery can no longer hold its charge & will need to be replaced. These 80m AH, 1.2v Ni MH batteries will bring your outdoor solar lights, whether decorative or practical, back to light! Perfect for solar lights requiring a 1/3rd AAA size battery. With four in the pack, you’ll have plenty to replace any tired batteries & maybe even have some for spares, just in case.
