Eliminate Downtime:
The Ultimate AGM Upgrade
for Industrial Barrel Lifters.
Replace standard 80Ah flooded batteries with 120Ah of military-grade, maintenance-free power. Engineered for severe vibration resistance and extended shift runtimes in Morse and similar heavy-duty lifts.

Problem
The Flooded Battery Liability
Legacy flooded cells weren't built for the duty cycle your lifters see. The failure pattern is predictable — and expensive.
Acid leaks
Sulfuric electrolyte corrodes lift chassis, terminals, and wiring harnesses.
Daily PM burden
Water-level checks and equalization pull techs off the floor every shift.
Vibration failure
Lead plates fracture under continuous lift cycle vibration.
Undersized capacity
80–100Ah cells die mid-shift, stranding loads and operators.
Solution
VMAX Heavy-Duty AGM Technology
VRLA construction, military-grade plate alloys, and absorbed glass mat separators — engineered for the abuse.
99.9% maintenance-free
Sealed VRLA. No watering, no equalization, no acid spills.
Military-grade alloys
Custom-cast plates resist shedding under deep-cycle abuse.
Shock & vibration rated
AGM mat immobilizes electrolyte — survives constant lift motion.
120AH DEEP CYCLE CAPACITY
120Ah in the same Group 31 footprint as your 80Ah factory cell.

The Standard, Upgraded
VMAX MR137-120
A true deep-cycle Group 31 drop-in replacement that delivers a massive 120Ah capacity — outperforming standard 80Ah market alternatives by up to 50%.

Double Your Operating Capacity:
Dual-Battery Lift Configurations
Many lift manufacturers, including Morse, support a factory-installed secondary battery. You can instantly double your runtime by adding a secondary battery box and running two MR137-120 units in parallel.
Net result
240Ah of usable AGM capacity — one full extra shift, zero PM.

VBB-31 Adjustable Battery Box
Securely mount your secondary Group 31 battery to the lift chassis. Adjustable for Group 24–31 footprints.
