Battery technologies

Grand Battery Technologies SA (Pty) Ltd. (GBT) started in 1999 with the aim of focusing on renewable energy. GBT started the business with GrandCELL Rechargeable Alkaline Batteries (RAM) which are inherently different to any other rechargeable batteries on the market, as it is a rechargeable replacement to the single use alkaline 1.5 volt batteries we have become accustomed to and use in everyday items. Not only does this technology replace single use batteries, it doesn’t contain any toxic mercury, cadmium or heavy metal which makes it environmentally friendly. GBT also offers the GrandCELL Rechargeable Digital Batteries which are 1.2 volt batteries and are commonly used in digital applications. Over the last few years GBT has extended their range of products which now includes solar powered lighting, namely GrandSolar.

The reason for this is because batteries and solar go hand in hand. Without a good battery you can’t expect to have a good solar product. This is what sets us aside from other solar lighting products on the market as we are primarily a battery company specializing in various environmentally safe battery technologies, hence making us the leading brand in solar powered lighting.

Each component of the GrandSolar light ensures optimum output.

1. The stainless steel or high quality UV resistant plastic Housing protects the electronics.

2. The Solar Panels collect the sunlight and convert it into energy, which is used to charge he GrandCell Rechargeable Batteries.

3. The Batteries are used at night to power the Light Emitting Diodes (LED’s)

4. LED’s are used as they draw very little energy from the batteries and therefore ensure longer illumination time, they also last up to 100000 hours and therefore do not need to be replaced.

The only component within the solar light that requires replacing are the batteries inside, and this needs to be done, on average, every 10 months.

GrandSolar has a wide product range which can be divided into various categories.

Our smaller lights are called Garden Accent Lights, these are considered atmospheric lighting and add character to your garden landscape at night.

The Pathway lights, start with the ‘Solar Brick’, that is embedded into one’s paving to larger lamps that are positioned along a path, each with a minimum of 4 LED’s to provide more light to the immediate area.

Security lighting, with or without sensors; that provides security lighting even during power cuts.

Deco lights add colour to the night. This range includes the very popular pool balls and extends to the decorative dragonflies and gnomes.

GrandSolar range for outside lighting is completed by larger lighting solutions for parking, street lights, home kits and solar panels. These can be used for office parks, game farms and housing developments in order to reduce the reliance on Eskom generated power for outside and inside lighting.

GrandSolar prides itself to be associated with the World Wildlife Fund (WWF) to support their charter for a clean and sustainable environment. This has become more important with the climate change crisis.
In this context, GrandSolar only uses battery technology that is environmentally compatible and DO NOT contain any heavy metals such as Cadmium and Mercury.
