VRLA battery AM series

Product catalog summary

Overview: AINO MICRO Range VRLA batteries are maintenance-free, sealed lead-acid batteries with capacities from 0.8AH to 70AH. They are designed to handle overcharge, over-discharge, vibration, and shock, providing reliable power in a compact form.

Specifications: These batteries function within a temperature range of -40°C to +70°C, with an optimal range of +20°C to +28°C. They can be stored for up to 12 months at 20°C~25°C and are classified as non-hazardous for transport by land, sea, and air.

Innovative Features: The batteries have a design life of 5-8 years at 20°C, maintaining 80% capacity. They utilize high-compression absorbed glass mat technology for over 99% recombination efficiency, have a low self-discharge rate, and are UL recognized. The construction includes a lead calcium tin alloy grid and high-impact resistant ABS resin cases.

Applications: Suitable for uninterrupted power supplies, security systems, medical equipment, consumer electronics, telecom equipment, and more.

Construction: The batteries use a calcium/tin lead alloy for grids, high purity lead for active material, and a glass micro-fibre separator to prevent short circuits. They are maintenance-free with a safety release valve to manage pressure.

Electrical Specifications: The batteries offer various ampere-hour capacities at different discharge rates and have specific internal resistances and maximum charge/discharge amps.

Discharge Data: Detailed discharge data is provided for different models, showing performance over time at various voltages.

Battery Cycle Service and Depth of Discharge: Battery performance in cycle service is influenced by the depth of discharge. Deeper discharges result in fewer available cycles.

Charge Retention and Self-Discharge: AINO MICRO Batteries have excellent charge retention with a low self-discharge rate of less than 3% per month at 20°C. A fully discharged battery typically has an open circuit voltage of 1.92 VPC and requires immediate recharging to 100% capacity.

Final Acceptable Discharge: The final discharge voltage per cell varies with discharge current: up to 0.1 CA: 1.75 VPC, 0.11 to 0.17 CA: 1.70 VPC, 0.18 to 0.25 CA: 1.67 VPC, 0.26 to 0.6 CA: 1.60 VPC.

Supplementary Charge and Storage: A refresh charge may be necessary if storage exceeds recommended times or if the open circuit voltage falls below 12.40 volts per battery. The refresh charge should be at 2.25-2.35 VPC for at least 12 hours.

Sulphation and Self-Discharge: Lead sulphate forms during discharge and can be reversed if recharged promptly. However, self-discharge can lead to irreversible sulphate formation, damaging the battery.

Storage Precautions: Batteries should be stored in a cool, dry place at 25°C or below, away from direct sunlight and external heat sources. A stock control system is recommended.

Storage Temperature Guidelines: 20ºC or less: Refresh every 9 months; 20ºC – 30ºC: Refresh every 6 months; 30ºC – 40ºC: Refresh every 3 months.

AINO MICRO Range VRLA CONSTRUCTION - EverExceed AINO MICRO Range AGM battery construction is as shown in the diagram below. The positive and negative grids are cast from a calcium / tin lead alloy to reduce grid growth and corrosion. The active material is manufactured from high purity lead (99.9999%) to minimize the negative effects of impurities. Separator is mat of random woven acid resistant glass fibres, which acts as sponge - soaking up and immobilizing the electrolyte whilst maintaining good acid to plate contact and availability during discharge. “U wrapping” is employed to eliminate...

power your applications Battery Life Battery Life depends on a number of key factors, these include: n Operating temperature of the battery; n Actual use of the products i.e. Float or cycle service; □ Method of charging; □ Correct sizing etc. Float Service The float service is effected by the factors listed above and the number / depth of discharge the battery suffers during its life time. Basically the more discharges suffered and the deeper the discharges, the shorter battery life. Cycle Service Giving due consideration to the above key factors, the actual life of a battery in cycle service...
