Soluminate
Why we love it
High-quality UK-made batteries.
Perfect size for solar lights.
Rechargeable for eco-friendly convenience.
Main Highlights
Soluminate is a UK brand sold by a UK Based Seller. Selected Size and Quantity : 10 x 2/3AAA rechargeable solar light batteries supplied. 2/3AAA are two thirds of the size of a normal AAA. So just 29.5mm in length. 10mm in Diameter.
Please check the size you require is 2/3AAA. (29.5mm x 10mm) These 2/3AAA batteries are two thirds the size of a normal AAA battery. So these are smaller than the full size AAA.
These brand new rechargeable 2/3AAA solar light batteries will charge up in 48 hours if the solar lights are in good working order. Replacing the batteries will not fix solar lights that are broken, water damaged, rusty or faulty.
Top Tip : Try cleaning the solar panel on your lights to allow the batteries to charge. Try to position your solar lights in a good sunny spot.
Trouble Shooting : If your solar light stays lit during the day please clean the top of the solar light including the solar panel to allow light to the sensor. Once the daylight hits the sensor the light will turn off. A dirty solar panel or cover may convince the solar light it is night time and therefore turning the light on during the day.
