Batteries are assembled in the UK to meet your specifications of size and capacity. About 50% of our batteries are rescued laptop batteries in excellent conditions and saved from landfill. 

We tend to use primarily Japanese brands like Sony and Panasonic as we have seen they are pretty reliable and hold a charge.

Every battery is fitted with a BMS or Battery Management System to protect the battery from operating outside its safe operating area, monitoring its state.
