Direct Cross-Reference
Both batteries are Group 27 AGM and drop directly into the original JLG tray. Choose the standard MB127-100 for daily duty or step up to the XTR27-110 Xtreme for multi-shift, hard-cycled fleets.
Heavy-duty VRLA AGM deep-cycle built for daily lift duty. Drop-in fit for any JLG bay specifying the 0400209 — same footprint, same terminals, longer service life.
VMAX Xtreme series — 10% more capacity and dramatically deeper cycle life than standard AGM. Built for multi-shift lifts and aggressive opportunity charging.
Every VMAX battery is engineered to drastically outperform standard OEM SLA batteries. We don't build "entry-level" options — both the MB and XTR series are premium, heavy-duty deep-cycle powerhouses designed to maximize the uptime of your JLG equipment.
The MB Series instantly elevates your lift's capabilities compared to factory-issued SLA batteries. Built with custom-alloy grids and elite AGM technology, this heavy-duty deep-cycle battery is the definitive upgrade for rigorous daily facility maintenance and construction.
The XTR Series takes VMAX high-performance engineering to the absolute limit. It builds on our premium MB foundation with an enhanced, extreme-duty plate design — delivering a distinct operational edge in three critical categories:
Both VMAX batteries are direct fitments across the JLG product line wherever the OEM specifies 0400209 or 1001178278. If you're unsure, our team will confirm fitment from your serial number.
Both replacements share the JLG Group 27 footprint. The XTR27-110 adds capacity and dramatically extends deep-cycle life.
