Built to Last with PowerFrame® Grid Technology
PowerFrame® grid Technology is nearly three times more corrosion resistant*, making Delkor batteries more durable than other batteries on the market. The PowerFrame® grid design is optimised for full grid utilisation, providing more than 60% superior electrical flow* for better connectivity. Another benefit of this technology is that manufacturing PowerFrame® grids uses 20% less energy and produces 20% fewer greenhouse gases compared to other manufacturing methods.
*Based on comparison to other grid designs in real world fleet testing.
