Smarten Saver 150 ah Solar Tubular Battery

The Smarten Saver 150 AH (Model: SRTT 1500) is a high-performance Tall Tubular Lead-Acid battery specifically engineered for solar energy storage and deep-cycle applications.¹ Produced by Smarten Power Systems, this battery is designed to handle the rigorous demands of solar power cycles and long-duration power outages.²

Below is the comprehensive technical specification and detailed breakdown of the Smarten Saver 150 AH battery.

1. Electrical & Capacity Specifications

The “150 AH” capacity of the Smarten Saver is rated at the C10 standard, which is the preferred rating for solar applications.³ A C10 rating means the battery can deliver 15 Amperes of current consistently for 10 hours.

• Nominal Voltage: 12V DC

• Rated Capacity (C10): 150 AH @ 27°C⁴

   

• Watt-Hour Capacity: Approximately 1,800 Wh (1.8 kWh)

• Ampere-Hour Efficiency: ⁵$\geq 91.6\%$ (Reflects very low energy loss during the charge-discharge cycle)⁶

   

• Watt-Hour Efficiency: ⁷$> 90\%$

   

• Self-Discharge Rate: ⁸$\leq 3\%$ per month at 27°C (standard batteries often lose 10% or more)⁹

   

• Initial Charging Current: 11.0 Amperes (Ideal for maintaining plate health)¹⁰

   

2. Physical Construction & Dimensions

The battery utilizes the Tall Tubular design, which provides a larger electrolyte volume and more vertical space for the plates, helping to prevent overheating and premature drying.

• Length: 503 mm – 505 mm

• Width: 190 mm – 193 mm¹¹

   

• Height: 412 mm – 505 mm (Including terminal height)¹²

   

• Dry Weight: ~44 kg¹³

   

• Wet Weight (with Acid): ~60.3 kg¹⁴

   

• Container Material: High-impact, leak-proof PPCP (Polypropylene Co-Polymer)¹⁵

   

• Terminal Type: L-Terminal with Antimony Lead Alloy (Rust-proof technology)¹⁶

   

• Separator: High-porosity PE (Polyethylene) for better ion movement

3. Core Technologies & Features

A. Hi-Power Selenium Grid Technology

Unlike conventional lead-acid batteries that use lead-antimony grids, the Smarten Saver uses a Lead-Selenium alloy.¹⁷ This technology is the secret behind its low maintenance. It significantly reduces water evaporation and grid corrosion, making the battery almost “self-sustainable” for long periods.¹⁸

B. Deep Discharge Recovery (JTB Technology)

The battery is built with Jumbo Tubular Battery (JTB) technology. It is a “Programmable Battery,” meaning it can be recovered even if it has been left in a completely discharged (zero-volt) state.¹⁹ This is critical for solar users whose panels might not receive sunlight for several days.

C. Solar Optimization

While standard batteries are designed for occasional power cuts, the Saver series is optimized for Daily Cycling. It works seamlessly with MPPT and PWM solar charge controllers, effectively managing the variable charging current produced by solar panels.

4. Charging & Maintenance Parameters

To maximize the lifespan (typically 5–7 years), the following charging settings are recommended:

• Bulk/Boost Voltage: 14.5V – 14.8V

• Float Voltage: 13.7V ± 0.2V

• Low Battery Cut-off: 10.4V

• Electrolyte Specific Gravity (Full Charge): 1.240 at 27°C²⁰

   

• Electrolyte Specific Gravity (Discharged): 1.130²¹

   

• Operating Temp Range: -20°C to +60°C²²

6. Warranty & Reliability

• Standard Warranty: 60 Months (typically 36 months full replacement + 24 months pro-rata).

• Applications: Banks, IT Parks, Telecommunications, Railways, and Residential Solar Off-grid systems.²³

   

Important Note: Always check the 6 water level (float) indicators every 3 months. Only use distilled water for topping up. Tap water contains minerals that will permanently damage the tubular plates and void the warranty.
