The ETERNITY series gel-block batteries from ETERNITY (model range S06-12-xxx) are high-performance, deep-cycle, maintenance-free (VRLA gel) batteries designed for renewable energy, inverter backup and off-grid installations. These two variants—12 V 110 Ah (S06-12-100) and 12 V 200 Ah (S06-12-200)—offer reliable energy storage, suitable for systems where charging/discharging cycles matter and downtime must be minimised.
Features & Benefits
- Maintenance-free sealed design: The gel-electrolyte VRLA construction means no water topping up or regular maintenance is required, simplifying installation and reducing upkeep.
- Deep-cycle capability: Built for repeated charge/discharge cycles, making it well-suited for inverter systems, off-grid solar applications, backup power for homes, businesses and telecoms.
- Wide temperature tolerance: Designed to operate in challenging environmental conditions — useful for regions with fluctuating temperatures or harsh climates.
- Low self-discharge: When the system is idle or stored, minimal charge is lost over time, allowing better readiness when needed.
- Safety & transport friendly: Classified as non-spillable VRLA gel battery; lower risk of leaks; compliant with relevant transport standards for sealed batteries.
- Recyclable materials: The battery is designed with end-of-life recycling in mind, aligning with sustainable practices.
Use Cases
- Residential inverter backup: For homes in Tanzania experiencing grid instability or load-shedding, pairing these batteries with appropriate inverters (12 V systems) ensures lights, fans, TV, perhaps a small fridge can keep running.
- Off-grid solar installations: Small solar systems (e.g., 12 V PV arrays) with charge controllers and inverters: these batteries store the generated energy during sun hours for evening/night use.
- Commercial or small-business backup: Shops, clinics, offices or tele-communications sites that require reliable backup power; the 200 Ah variant offers larger capacity for heavier loads or longer autonomy.
- Telecom/remote installations: Sites in remote locations (tower base stations, monitoring units) where maintenance visits are costly — sealed deep-cycle batteries reduce the need for frequent servicing.
- Hybrid energy systems: Coupled with grid/solar/generator systems in small-scale hybrid configurations, especially in Tanzania’s growing energy-access market.
Value Propositions
- Reliability in challenging conditions: With the ability to operate in wide temperature ranges and deep cycle demand, these batteries suit Tanzania’s environment – whether in inland regions, rural off-grid locations or coastal communities.
- Maintenance savings: The maintenance-free aspect reduces the burden of upkeep in locations where skilled servicing may be limited or travel costs for engineers are high.
- Asset for solar growth: Tanzania has strong solar potential and increasing demand for reliable backup power. These batteries support that trend, allowing both residential end-users and installers to offer more robust systems.
- Local import/stock-point advantage: Assuming local availability (you mention “Target Market: Tanzania”), having a stock of these batteries means faster delivery, local after-sales and supporting local partners gives a competitive edge.
- Scalable options: Having both 110Ah (100 Ah category) and 200Ah variants lets installers and buyers choose capacity appropriate to their load and budget, scaling up as needed.
- Eco-conscious selling point: With the recyclability and sealed safe design, you can position the product as a modern, safe battery solution compared to older flooded lead-acid types that require regular maintenance and produce more spillage risk.
