OPzV Tubular Gel Battery for Southeast Asia Telecom: 6-Country Procurement Guide (2026)
For telecom BTS site integrators and tower operators across Southeast Asia, the OPzV tubular gel battery is the dominant backup power technology for new deployments in 2026. The combination of high temperature tolerance (which matches SEA ambient), zero maintenance requirements (which matches the difficulty of sending technicians to remote tower sites), and long float life (which matches the 5–10 year replacement cycle preferred by ASEAN MNOs) makes OPzV the default specification for greenfield telecom projects in Indonesia, the Philippines, Vietnam, Thailand, Myanmar, and Cambodia.
This guide walks through CHISEN’s OPzV product line for telecom applications, shows you which model fits which BTS site configuration, and provides the procurement framework that ASEAN telecom system integrators use to source OPzV batteries at scale.
Why OPzV Is the Standard for Southeast Asia Telecom
Six operational factors make OPzV the standard telecom backup power chemistry in Southeast Asia:
1. High temperature tolerance. OPzV cells operate continuously at ambient temperatures up to 35°C without active cooling, and can survive peaks of 45°C with appropriate derating. The Philippines, Indonesia, Vietnam, Myanmar, and Cambodia all have average ambient temperatures above 28°C year-round, with peak temperatures above 40°C at coastal and equatorial sites. OPzV’s tubular gel chemistry handles this with minimal capacity loss.
2. Zero maintenance requirement. The gel electrolyte is immobilized, which means no water top-up is required over the battery’s lifetime. For remote tower sites in Indonesia (Kalimantan, Papua, Sulawesi), the Philippines (Palawan, Mindanao), and Myanmar (Rakhine, Kachin), the cost of sending a technician to perform water top-up can exceed the cost of the battery itself. OPzV eliminates this cost.
3. Long float life. OPzV cells deliver 18–20 years of float service at 25°C, which means a single battery installation can outlast two generations of telecom equipment upgrades. Most ASEAN MNO procurement contracts specify 10-year battery life, and OPzV exceeds this by 8–10 years.
4. Deep discharge recovery. OPzV cells recover fully from repeated deep discharges (down to 80% DoD), which is essential for telecom sites with intermittent grid power. When the grid fails for 6–12 hours (a common occurrence in Indonesia, Myanmar, and the Philippines), the OPzV battery discharges deeply, then recharges fully when grid power returns — without permanent capacity loss.
5. Low self-discharge. OPzV cells self-discharge at approximately 1.5–2% per month at 25°C, which means a fully charged battery can sit on the shelf for 6 months without significant capacity loss. This simplifies inventory management for telecom system integrators who maintain regional battery stockpiles.
6. No acid mist or hydrogen emission. OPzV is sealed and recombines internal gases, which means it can be installed in equipment rooms without dedicated battery ventilation. This saves construction cost in space-constrained urban BTS sites (Manila, Jakarta, Bangkok, Ho Chi Minh City, Hanoi).
CHISEN OPzV Models for Telecom Applications
CHISEN offers the OPzV series in capacities from 100Ah to 3,000Ah (at the C10 rate to 1.80Vpc end voltage). For telecom BTS applications, the most common models are:
| Model | Capacity (C10) | Length | Width | Height | Weight | Typical Telecom Use |
|---|---|---|---|---|---|---|
| 12V 100Ah OPzV | 100Ah | 103 mm | 206 mm | 354 mm | 13.5 kg | Small cell site / mini-BTS |
| 12V 150Ah OPzV | 150Ah | 124 mm | 206 mm | 354 mm | 18.0 kg | Macro cell site (single sector) |
| 12V 200Ah OPzV | 200Ah | 145 mm | 206 mm | 354 mm | 22.0 kg | Macro cell site (3 sectors) |
| 2V 200Ah OPzV | 200Ah | 103 mm | 206 mm | 354 mm | 13.5 kg | Standard 48V string building block |

| 2V 500Ah OPzV | 500Ah | 166 mm | 206 mm | 471 mm | 30.0 kg | High-capacity 48V string building block |
| 2V 600Ah OPzV | 600Ah | 145 mm | 206 mm | 646 mm | 35.0 kg | 2-hour backup at heavy load |
| 2V 800Ah OPzV | 800Ah | 191 mm | 210 mm | 646 mm | 49.0 kg | 4-hour backup at heavy load |
| 2V 1000Ah OPzV | 1000Ah | 233 mm | 210 mm | 646 mm | 60.0 kg | 6-hour backup at heavy load |
| 2V 1200Ah OPzV | 1200Ah | 275 mm | 210 mm | 646 mm | 71.0 kg | 8-hour backup at heavy load |
| 2V 1500Ah OPzV | 1500Ah | 340 mm | 210 mm | 646 mm | 86.0 kg | 10-hour backup at heavy load |
| 2V 2000Ah OPzV | 2000Ah | 399 mm | 214 mm | 772 mm | 118.0 kg | Central office main battery |
| 2V 3000Ah OPzV | 3000Ah | 576 mm | 214 mm | 772 mm | 178.0 kg | Central office main battery (high capacity) |
The 2V cells are the standard building block for telecom 48V battery strings (24 cells in series for 48V nominal). The 12V models are designed for small cell sites and mini-BTS installations where a 24-cell 2V string is over-spec and a single 12V battery is sufficient.
String Sizing for Typical BTS Configurations
The standard 48V telecom battery string is 24 cells of 2V OPzV in series. The total string capacity depends on the cell capacity:
| Site Type | Load | Backup Time | Recommended Cell | String Capacity |
|---|---|---|---|---|
| Small cell site (1 sector, no microwave) | 1.5 kW | 4 hours | 2V 300Ah | 14.4 kWh |
| Macro cell site (3 sectors, microwave) | 3.0 kW | 4 hours | 2V 600Ah | 28.8 kWh |
| Macro cell site (3 sectors, microwave) | 3.0 kW | 8 hours | 2V 1200Ah | 57.6 kWh |
| Macro cell site (3 sectors, 4G LTE) | 5.0 kW | 4 hours | 2V 1000Ah | 48.0 kWh |
| Macro cell site (3 sectors, 4G LTE) | 5.0 kW | 8 hours | 2V 2000Ah | 96.0 kWh |
| Hub site (multiple BTS) | 10.0 kW | 6 hours | 2V 3000Ah | 144.0 kWh |
| Central office | 20.0 kW | 8 hours | 2V 3000Ah × 2 strings | 288.0 kWh |
For a typical ASEAN macro cell site with 3 sectors, 4G LTE equipment, and a 5 kW load, the standard configuration is 24 × 2V 1000Ah OPzV in series. This delivers 48V × 1000Ah = 48.0 kWh of total string energy, which supports 4 hours of backup at full load or 8 hours at half load.
Pricing for ASEAN Telecom Procurement
CHISEN’s OPzV pricing for telecom procurement follows a 4-tier volume structure:
| Model | 100 units | 500 units | 1,000 units | 5,000 units (40HQ container) |
|---|---|---|---|---|
| 2V 200Ah | $185 | $172 | $165 | $152 |
| 2V 300Ah | $248 | $232 | $220 | $205 |
| 2V 420Ah | $315 | $295 | $280 | $260 |
| 2V 500Ah | $395 | $370 | $352 | $328 |
| 2V 600Ah | $450 | $420 | $398 | $370 |
| 2V 800Ah | $595 | $555 | $528 | $490 |
| 2V 1000Ah | $735 | $688 | $655 | $610 |
| 2V 1200Ah | $880 | $820 | $780 | $725 |
| 2V 1500Ah | $1,090 | $1,020 | $970 | $900 |
| 2V 2000Ah | $1,455 | $1,360 | $1,295 | $1,205 |
| 2V 3000Ah | $2,180 | $2,040 | $1,940 | $1,805 |
For a typical macro cell site order (24 × 2V 1000Ah), the per-site battery cost is 24 × $655 = $15,720 at the 1,000-unit tier. For a regional rollout of 100 sites, the total battery cost is $1,572,000. A 40HQ container holds approximately 1,200 2V 1000Ah cells, which is enough for 50 sites at the standard 24-cell string configuration.
ASEAN Country-Specific Procurement Notes
Indonesia — The most active market for OPzV telecom batteries in ASEAN, with major deployments by Telkomsel, XL Axiata, and Indosat. The Indonesian climate (28–32°C average, 35°C peak) requires batteries with high temperature tolerance. CHISEN’s OPzV cells are rated for continuous operation at 35°C with appropriate temperature derating. Import duty on batteries is 7.5% (MFN) plus 11% VAT. SNI certification is recommended but not mandatory for telecom backup applications.
Philippines — Globe Telecom and Smart Communications are the major deployers. The Philippines has the most challenging grid reliability in ASEAN, with typical grid outages of 4–8 hours in provincial areas. This drives demand for higher-capacity strings (2V 1500Ah or 2V 2000Ah) to support longer backup times. Import duty is 5% (MFN) plus 12% VAT. No special certification required.
Vietnam — Viettel, Vinaphone, and Mobifone are the major deployers. Vietnam’s telecom market is growing rapidly, with new 5G deployments in 2025–2026 driving battery procurement. Import duty is 5% (MFN) plus 10% VAT. CR certification (CIRC) is not required for OPzV batteries.
Thailand — AIS, TrueMove, and DTAC are the major deployers. Thailand has the most stable grid in mainland ASEAN, which means 2–4 hour backup strings are typically sufficient. TISI certification is not required for OPzV batteries. Import duty is 5% (MFN) plus 7% VAT.
Myanmar — MPT, Telenor Myanmar (now Atom), and Ooredoo are the major deployers. Political instability in 2021–2024 slowed new deployments, but 2025–2026 has seen renewed investment in rural coverage. Import duty is 3% (MFN) plus 5% commercial tax. The challenging logistics environment makes OPzV’s zero-maintenance requirement particularly valuable.
Cambodia — Cellcard, Smart Axiata, and Metfone are the major deployers. Cambodia’s market is smaller but growing, with new 4G LTE rollouts in provincial areas. Import duty is 7% (MFN) plus 10% VAT. No special certification required.
Lead Time, Logistics, and After-Sales Support
Standard OPzV production orders run on a 25-day lead time for orders under 500 cells and 40–45 days for full container loads. MOQ is 100 cells per model for the standard SKU; custom branding requires 500-cell MOQ and a 60-day lead time.
For ASEAN destinations, CHISEN ships FOB Ningbo or Shanghai with sea freight of 14–18 days to Manila, Jakarta, Bangkok, Ho Chi Minh City, and Yangon. DDP terms are available for major ports.
CHISEN’s after-sales support for ASEAN telecom includes a 36-month warranty from B/L date, regional spare cell inventory in Singapore (for rapid replacement of failed cells), and on-site technical training for installer teams on request.
Frequently Asked Questions
What is the difference between OPzV and OPzS for telecom?
OPzV uses gel electrolyte (immobilized), while OPzS uses flooded electrolyte (liquid). OPzV requires no maintenance, while OPzS requires periodic water top-up. For remote telecom sites where technician access is difficult, OPzV is the correct choice. For central office installations with easy maintenance access, OPzS is acceptable and slightly cheaper.
How long does OPzV last in ASEAN climate?
At 25°C ambient, OPzV delivers 18–20 years of float life. At 35°C ambient (typical ASEAN tower site), the float life is reduced to approximately 12–14 years due to accelerated plate corrosion. At 40°C ambient (coastal equatorial sites), the float life is further reduced to approximately 9–11 years. CHISEN’s warranty of 36 months covers the early-failure period; the typical replacement cycle in ASEAN is 8–10 years.
Can OPzV be transported by air?
CHISEN’s OPzV cells are sealed and pass the IATA DGR test (UN 2800 Special Provision A67) for air freight. However, due to the high weight of telecom OPzV strings, sea freight is more cost-effective for full container loads. Air freight is typically used only for emergency cell replacement shipments.
What about temperature compensation?
The float voltage should be temperature-compensated at -3mV/°C/cell for OPzV. At 35°C ambient, the float voltage is 2.23Vpc instead of the standard 25°C value of 2.25Vpc. CHISEN’s installation guide includes the temperature compensation table for ambient temperatures from 15°C to 45°C.
Can I mix OPzV cells of different capacities in the same string?
No. Mixing different capacity cells in a series string forces the smaller cells into over-discharge, which destroys them quickly. Always use identical capacity cells across the entire 24-cell string.
