Use the figure on the specification sheet for your specific model, and use a torque wrench. There is no universal value, it varies with terminal design, thread size and insert construction. Valen’s front terminal ranges are specified at 7 Nm (ENVIROX-CEL, ENVIROX-CELPLUS and TOPIN) and 10.3 Nm (ENDUROGEL). Both errors cause failures: Under-torqued connections have […]
Range Warranty ENDUROGEL 24 months ENVIROX-CEL 24 months ENVIROX-CELPLUS 24 months TOPIN Front Terminal 24 months ENLiFEN Front Terminal 36 months Extended warranty is available on request. You will notice the gap between warranty and design life, 24 months against a 15-year design life on ENDUROGEL, for example. That gap is normal across the industry […]
Industrial lead-acid is recycled through the established commercial scrap-lead route, which has been economically self-sustaining for decades because of the scrap value of lead. Practically, a supplier or a licensed recycler collects the old batteries and provides documentation. Valen Power is certified to ISO 14001:2015 for environmental management, covering the provision of industrial batteries, energy […]
For Valen’s VRLA front terminal ranges, ENDUROGEL, ENVIROX-CEL, ENVIROX-CELPLUS and TOPIN, yes. The electrolyte is immobilised, the batteries are classified non-spillable and approved for air transport under IATA packing instructions, subject to correct packaging, marking and terminal protection. This matters more than it sounds for remote-site work, where the difference between air freight and road […]
Temperature is the dominant variable in Australian industrial battery life, and it is under-modelled almost everywhere. The relationship. EUROBAT states that float operation above 20 °C reduces VRLA life expectancy by approximately 50% for every 10 °C of sustained increase. Applied to a 15-year design-life battery: roughly 7.5 years at 30 °C, roughly 3.75 years […]
Always check the rate. A 100 Ah battery at C₁₀₀ is not a 100 Ah battery at C₁₀, and comparing two batteries at different rates is the single most common sizing error in this category. The C-rating states the discharge period over which the capacity was measured. A battery rated 100 Ah at C₁₀ can […]
Thermal runaway is a self-reinforcing loop: elevated temperature increases charge current acceptance, the increased current generates more heat, the higher temperature increases current further. Left unchecked it dries the cell, deforms the case and can vent or rupture it. This is a recognised failure mode in utility battery fleets managing critical infrastructure—not theoretical. It occurs […]
You can, but in most cases you should not and the reason is duty cycle rather than quality. A standby battery, AGM front terminal designed for UPS or telecom float service, spends its life at full charge and is discharged rarely. Its plate design, separator and charge regime are optimised for that. A solar or […]
Yes, less than a flooded cell, but not none. VRLA batteries recombine most of the gas produced internally, which is why they are described as sealed and require no watering. But recombination is not perfect, and under over-charge, high temperature or fault conditions the pressure relief valves vent hydrogen. Hydrogen is flammable in air at […]
Battery end-of-life and testing approaches. The industry convention is end of life at 80% of rated capacity—the point at which the battery can no longer be relied on to deliver its specified runtime. This is applied explicitly across critical infrastructure. Three approaches to determining end of life, in increasing order of reliability: Age-based. Simple but […]
It is the ENLiFEN 48 V 75 Ah lithium front terminal pack (ELFT4875322), a LiFePO₄ battery in a front terminal format, 530 mm long (560 mm including handles) × 125 mm × 330 mm, 34 kg, M8 terminals, rated at 6,000 cycles to 80% depth of discharge. It exists because some applications need a 48 […]
Usually not, and this is the most commonly misapplied standard in the Australian battery market. AS/NZS 5139:2019 covers battery systems used with power conversion equipment, 12 V to 1500 V DC, capacity 1 kWh to 200 kWh. It explicitly excludes: telecommunication applications uninterruptible power systems in accordance with AS 62040 premises with critical power continuity […]
