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 technology pattern 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 than other manufacturing methods.

*Based on comparison to other grid designs in real world fleet testing.


The Delkor AGM and Delkor EFB ranges are able to meet the demanding requirements of modern automotive technologies including Idle-Stop-Start (ISS) and regenerative braking systems. Strong PowerFrame®® grid plates enable Delkor Calcium-Calcium SMF batteries to exceed strict OEM and OE replacement standards. The Silver-Calcium range also incorporates added silver into positive plate alloys for superior resistance to corrosion, even in high temperature environments.
