These Gruber replacement AGM (VRLA) batteries are individual cells designed to match the form factor and electrical characteristics used in battery cartridges. They are not a finished RBC5 module — instead, they provide the high-quality 12 V cells you need when you want to rebuild your existing APC tray and harness yourself.
A typical cartridge is built from two 12Â V, 9Â Ah sealed lead-acid batteries wired together in the original APC plastic tray and harness. By reusing your existing bracket and cabling and installing fresh cells, you can restore runtime and reliability while keeping more hardware out of the landfill.
