Industrial battery storage racks are purpose-built steel racking systems for storing lithium-ion batteries, lead-acid batteries and forklift batteries horizontally or on multiple levels. They must meet three essential requirements: resistance to acid/alkali corrosion, concentrated loads of 500–1,500 kg per position, and ventilation clearances, with fire safety aligned to NFPA 855 and Vietnam’s fire safety code QCVN 06:2022/BXD. Indicative 2026 prices range from VND 1.8–5.5 million per linear metre depending on load capacity and anti-corrosion coating.
Key takeaways
- Battery racks differ from standard pallet racks in three ways: corrosion-resistant materials, ventilation gaps that let hydrogen escape, and electrolyte spill containment.
- Typical capacities: 300–800 kg per level for block-type forklift batteries, 100–300 kg per level for modular industrial lithium batteries.
- Fire and explosion hazard classification under QCVN 06:2022/BXD must be confirmed before rack spacing is designed – lithium and lead-acid batteries behave differently in a fire.
- Long Quyen manufactures at its own factory at 1085 Phuc Dien, Xuan Phuong, Hanoi, and can tailor acid-resistant epoxy coatings to each specific battery type.
- Lithium battery manufacturing in Vietnam is growing fast (industry examples include Gushine Electronics and Exquisite Power in Hai Phong), driving demand for compliant battery storage.

1. What is an industrial battery storage rack?
An industrial battery storage rack is a steel racking system designed specifically for storing, charging and rotating forklift batteries, industrial lithium-ion batteries or energy storage system (ESS) batteries in warehouses, charging stations and battery plants. Unlike standard pallet racking, which only has to carry loads and resist impact, a battery rack must solve three engineering problems at once: chemical corrosion from sulphuric acid vapour (lead-acid) or electrolyte solvents (lithium), heat build-up during charging, and the risk of fire or explosion if a battery short-circuits or overheats.
In Vietnam, this need is rising quickly alongside the wave of investment in lithium battery production – for example, Gushine Electronics opened a 22,000 m² lithium battery plant in Hai Phong (October 2025), and many other battery projects are under way in Hai Phong and Hai Duong. These plants and battery distribution warehouses need compliant storage racks rather than stacking batteries directly on the floor – a common practice that carries fire, explosion and impact-damage risks.
2. 6 mandatory technical features of battery racks
An industrial-grade battery rack must meet all of the following requirements – missing any one of them increases operational risk.
2.1. Acid/alkali-resistant coating
Lead-acid batteries release dilute sulphuric acid vapour during charging, which can corrode ordinary steel within just 12–24 months if a standard powder coat is used. Industrial battery racks need a dedicated acid-resistant epoxy coating or hot-dip galvanizing, 1.5–2 times thicker than a conventional powder coat.
2.2. Electrolyte spill containment trays
Every level holding lead-acid batteries needs a tray made of acid-resistant material (PP, PE or epoxy-coated steel) to stop electrolyte from leaking onto the floor or lower levels if a battery case cracks – the same principle as the spill pallets used in chemical storage racking.
2.3. Ventilation gaps for hydrogen release
Charging lead-acid batteries produces hydrogen, and a hydrogen/air mixture can ignite at just 4% by volume. The rack design must leave enough clearance between levels and at both sides for gas to rise and escape naturally, combined with mechanical ventilation in the charging area. This is required by US OSHA 1910.178(g) for forklift battery charging areas; Vietnam has no equivalent dedicated regulation yet, so companies usually apply this ventilation principle as engineering best practice.
2.4. Insulation between compartments
For industrial lithium batteries, modules placed side by side on the same level need a minimum spacing and insulating partitions to limit thermal runaway propagation if one module fails – a design principle addressed in NFPA 855 – Standard for the Installation of Stationary Energy Storage Systems.
2.5. Point loads, not uniformly distributed loads
Forklift batteries and block lithium packs are very dense (roughly 2–3 kg/dm³, several times denser than typical palletised goods), so their weight is concentrated on a much smaller area than a pallet of the same mass. Racks must be calculated for point loads where each battery sits, not just for a uniformly distributed load across the shelf.
2.6. Hazard classification before setting clearances
Before fixing aisle widths and distances to emergency exits, the fire and explosion hazard class of the storage area must be determined under QCVN 06:2022/BXD – lithium batteries are usually rated higher than lead-acid because fire spreads faster in an incident. This step must be confirmed by the local fire-safety approval authority for each battery type and warehouse size; no single figure applies to every case.
3. Reference specification table
The table below shows general industry reference ranges, not fixed specifications for a particular product – Long Quyen’s engineering team calculates exact figures after surveying your battery type, charging frequency and actual warehouse area.
| Parameter | Lead-acid battery rack (forklift) | Industrial lithium battery rack |
|---|---|---|
| Load per level (estimate) | 300–800 kg | 100–300 kg |
| Level spacing | 450–600 mm (with ventilation clearance) | 350–500 mm |
| Surface finish | Acid-resistant epoxy or hot-dip galvanizing | Anti-static powder coat or standard epoxy |
| Spill containment tray | Mandatory (PP/PE or epoxy-coated steel) | Recommended for batteries at risk of electrolyte leakage |
| Upright steel thickness | 2.0–3.0 mm | 1.8–2.5 mm |
| Typical number of levels | 2–4 | 3–6 (smaller, lighter modules) |
| Production lead time | 2–3 weeks | 2–3 weeks |
Key figure to remember: the concentrated load of a forklift battery can be 2–3 times the uniformly distributed load of ordinary palletised goods on the same shelf area – which is why standard selective racking cannot be used for large block batteries without recalculating beam and upright capacity.
4. Battery racks vs. other storage options
| Option | Suitable for batteries? | Limitations for battery storage |
|---|---|---|
| Directly on the floor / wooden pallets | Not recommended | No ventilation gap, easy to topple, no electrolyte spill control |
| Standard selective racking (not customised) | Only acceptable for light, sealed lithium packs | No acid-resistant coating; point loads of block batteries not calculated |
| Light-duty slotted angle shelving | Suitable for spare/small rechargeable battery stores, 50–150 kg per level | Insufficient capacity for large forklift batteries |
| Dedicated battery rack (Long Quyen) | Suitable | Initial investment 15–30% higher than standard racking |
Selection rule: if the warehouse only stores light, sealed lithium batteries and does no on-site charging, Long Quyen’s ready-made slotted angle shelving may be enough. If the warehouse charges forklift batteries or stores lithium batteries in large quantities, a dedicated rack with all 6 technical features in section 2 is essential.
5. Battery rack prices and cost drivers
Indicative 2026 prices for industrial battery racks range from VND 1.8–5.5 million per linear metre depending on configuration – a general industry estimate, not a fixed quotation. Actual cost depends on:
- Coating type: hot-dip galvanizing costs about 25–40% more than acid-resistant powder coating, but lasts 2–3 times longer in acid-vapour environments.
- Design load: thicker uprights for large block batteries increase the steel used per linear metre of racking.
- Spill trays and insulating partitions: additional safety accessories priced separately from the main rack frame.
- Order volume and project size: large orders for battery production lines (such as plants in Hai Phong) achieve a better price per metre than small orders thanks to optimised cutting and transport.
- Installation and transport: priced separately by location, typically 8–15% of the rack value.
We recommend requesting an on-site survey rather than relying on reference prices alone, as battery type, charging frequency and warehouse area directly determine the required configuration.
6. Long Quyen’s 5-step battery rack installation process
- Survey: measure the warehouse, identify the battery type (lead-acid or lithium), charging frequency, and the current or planned fire/explosion hazard class of the area.
- Design: calculate point loads from actual battery weights, define ventilation clearances, and select a corrosion-resistant coating suited to the electrolyte.
- Manufacturing: fabrication at our factory at 1085 Phuc Dien, Xuan Phuong, Hanoi, with coating thickness and load capacity checked before dispatch.
- Installation: erect the rack frame, spill trays and insulating partitions (if any), and check actual ventilation gaps against the design.
- Handover: load testing, levelness check, and comparison of actual fire-safety clearances with the approved fire-safety dossier (where the area requires approval).
7. Common mistakes in battery storage design
7.1. Using standard pallet racking without recalculating point loads
Placing forklift batteries directly on standard selective beams without checking point-load capacity – beams can deflect or fail even when the total load is within the uniformly distributed limit.
7.2. Omitting ventilation gaps between levels
Spacing levels too tightly to maximise capacity, leaving no room for hydrogen to escape when charging lead-acid batteries – increasing the risk of flammable gas accumulating in an enclosed space.
7.3. Mixing battery types in one area
Storing lithium and lead-acid batteries in the same rack run without separating zones – the two types have different fire behaviour and firefighting methods, complicating the fire protection plan.
7.4. Using ordinary powder coating instead of an acid-resistant finish
Saving on upfront cost with a standard powder coat, only for the racks to corrode and lose load capacity after 1–2 years in an acid-vapour environment.
7.5. No electrolyte spill trays
Skipping spill trays on the assumption that battery cases rarely crack – when an incident does happen, acid electrolyte flows straight onto the floor or lower levels, corroding the structure and endangering operators.
8. Frequently asked questions
Do battery racks have to be hot-dip galvanized?
Not strictly, but it is recommended for high-frequency lead-acid charging areas because its corrosion life is 2–3 times that of ordinary acid-resistant powder coating under the same conditions.
Do lithium battery racks need ventilation gaps like lead-acid racks?
Yes, but for a different reason – lithium batteries need spacing to limit thermal runaway between modules in an incident, while lead-acid batteries need gaps mainly to release hydrogen generated during charging.
Is battery rack capacity calculated by point load or distributed load?
By point load where each battery sits, because batteries are far denser than ordinary palletised goods on the same shelf area.
Does a battery storage warehouse need separate fire-safety approval?
It depends on scale and the hazard class under QCVN 06:2022/BXD – warehouses holding large quantities of lithium or lead-acid batteries usually require approval. Check with the local fire-safety approval authority for your specific case.
How long do production and installation take?
Standard rack frames take 2–3 weeks to manufacture; installation depends on warehouse size, typically 3–7 days for small and medium warehouses.
Can existing pallet racks be reused for forklift batteries?
Not recommended unless the racks have been re-checked for point-load capacity, anti-corrosion coating and ventilation clearance – three features standard pallet racks usually lack.
Can battery racks be installed in cold storage?
Yes, but material embrittlement at low temperatures and reduced battery performance in the cold must be taken into account – see our article on Long Quyen cold storage racking for low-temperature material principles.
Conclusion
An industrial battery storage rack is not just a pallet rack with plastic trays added – it is a system re-engineered from materials, point loads and ventilation clearances to spill containment to match the chemical and fire characteristics of each battery type. With experience since 1997 – nearly 30 years – and its own factory at 1085 Phuc Dien, Xuan Phuong, Hanoi, Long Quyen can customise coatings and rack configurations to the exact batteries your company stores. For warehouses operating on a first-in, first-out basis, also consider FIFO pallet flow racking to manage battery life cycles by batch.
