Many other manufacturers use older Nickel-Cadmium (Ni-Cd) technology batteries. These are far cheaper to produce, however are infamous for the dreaded “memory effect”. This means if the lights are only partially discharged before recharging, this “memory” stops the battery from being able to fully recharge therefore reducing future battery capacity. As a direct result, these batteries take more than twice as long to charge and have a much lower energy capacity.
Due to this significant “memory effect” Solar Lighting Direct lights use Nickel Metal Hydride (NiMH) Batteries, which give you:
1 Less “memory effect”
2 Quicker charge times
3 Longer lighting periods
