68% Lifespan Cost Savings Over Most Lead Acid and Lithium Batteries

Introduction

  • Silicate salt compound “world patent protected electrolyte”.
  • Advanced green technology, no acid mist, non corrosive and non explosive .
  • When the battery expires the battery can be refurbished to save on battery replacement.
  • High and low temperature endurance with superior high performance in harsh temperatures.

General Features

  • Non corrosive to plates, electrodes, joints and connections giving the battery a longer life while retaining charging cycles.
  • The Bolt Ultra Battery works normal in extreme harsh weather conditions between -40°C ~ +70°C.
  • Bolt Ultra Battery performs extremely well in hot outdoor environments. The VRLA battery loses approximately 50% of it’s cycles for every 8°c increase in temperatures exceeding 25°. The Bolt Ultra Battery loses approximately 10% in the same application.
  • The Bolt Ultra Battery has up to 2200 charging cycles when using 50% or less discharge. The battery has the capability to be discharged to 100% without damage to the battery but it is recommended to be charged immediately after high discharge to prolong the battery life and save charging cycles.
  • Self discharge rate is approximately 25% in two years when stored at ambient temperatures of 25°c.
  • The Bolt Ultra Battery has up to 50% higher specific energy density than that of the VRLA battery.
  • The Bolt Ultra Battery has a low internal resistance of 2Ω to 5Ω milliohm compared to that of the 12v lead acid battery with approximately 25Ω milliohm, the bolt ultra has little temperature rise during usage.
  • The Bolt Ultra Battery exceeds international storage capacity standards by 1.75 times and exceeds international recharge acceptance capacity standards by 2.68 times.
  • No separate enclosures, no ventilation or cooling systems required, saving on installations, maintenance and energy costs.
  • Bolt Ultra Battery life design is up to 15 years and up to 4500 to 5000 cycles in telecom standby applications.

Battery Charging

  • Due to the special capabilities of the Bolt Ultra Battery constant current charging is recommended to prolong the life of the battery. However, since the charging ability of the bolt ultra is quite strong, it can adapt to both constant voltage or constant current charging with minimal effect.
  • The top recommended charge voltage is 2.45v/cell. The Bolt Ultra will not get top loaded like lead acid batteries and will not undergo gas emission problems or battery damage.
  • When float charging the highest recommended acceptable current is 0.6c. The recommended float charge voltage per cell is 2.27v at 25°c. When using constant current charging the recommended voltage per cell is 2.35v that will fully charge the battery in three hours.
  • The Bolt Ultra has fast charge capability to be charged to 90% capacity in 60 minutes at 3c - 14.4v.
  • When charging with an ordinary lead acid battery charger with lower charging voltage, the Bolt Ultra Battery may not get fully charged to full capacity. Chargers are available to charge to the maximum charging capacity.

Battery Discharging

  • Due to the special capabilities of the Bolt Ultra Battery constant current discharging is recommended to prolong the life of the battery. However, since the discharging ability of the Bolt Ultra is strong it can adapt to both constant voltage or constant current with minimal effect.
  • Under normal circumstances charging and discharging ratio of 1:0.3 is recommended. However, with high current charging and discharging the ratio can be shifted to 1:1.
  • Bolt Ultra can withstand high discharge to 100% with no damage to the battery, however the manufacturer advises the end user to charge the battery immediately after high discharge to prolong the battery life and retain charging cycles. The manufacturer suggests not exceeding 90% discharge for a longer battery life.

Description

Originally designed and developed in 1992 for the military, Bolt Ultra Batteries deliver a much higher overall performance than lead-acid batteries. Utilizing a patented, proprietary electrolyte of liquid low-sodium silicate compound of ammonia sulfate, sodium carbonate and water, the Bolt Ultra Batteries has successfully overcome the drawbacks of lead-acid batteries used since the 70’s. These drawbacks include acid corrosion, acid mist pollution, low energy density & power density, and short life span. The newly designed neutral electrolyte does not corrode the electrodes, hence prolonging the battery cycle life.

The overall construction of the battery is very similar to lead-acid batteries that are on the market, utilizing a lead plate that the electrolyte reacts with. This makes replacing batteries with this technology very simple to employ.

Due to their high temperature performance and fast charging capability, Bolt Ultra Batteries also have a universally recognized edge over commonly used lead-acid batteries. VRLA (valve regulated lead- acid) batteries in general lose a considerable amount of capacity as the ambient temperature around the battery falls. With silicate batteries, they continue to function well in very cold or freezing environments without the need for external battery warmers or warm-up time. They are also functional at full capacity at very high temperatures where most VRLA batteries lose capacity due to dry out and lithium ion batteries become unstable, requiring vast amounts of air conditioning to cool them.

For fast charging capability, Bolt Ultra Batteries can be recharged to 90% capacity within 60 minutes with a high current charger. Other advantages include small internal resistance (reducing heat) and low self- discharge rate, where most VRLA batteries lose a considerable amount of capacity after just six months. Bolt Ultra Batteries can sit uncharged for two years with minimal adverse effects. There is also no off-gassing or temperature rise during charging and operation, therefore isolation is not required for gas emission, saving construction costs in many applications.

For renewable energy applications, utilizing programmed set-points in the charge controller for VRLA or Gel batteries will sufficiently charge the batteries. You can consistently bring the batteries down to a 50% DoD, giving a little added capacity to the rule of thumb with most Gel or AGM where you don't want to drop below 30%. Because of the low internal resistance, it eliminates the need for a BTS (battery temperature sensor) within the battery enclosure, further decreasing costs for additional components. One of the greatest benefits in using these batteries comes out of the silicate compound electrolyte’s properties at end of life. Because the battery is non-hazardous, the PH neutral solution consisting of Ammonium Sulfate can actually be utilized as a fertilizer. The recycling of the lead becomes much easier and environmentally sound as the electrolyte doesn't degrade the plate and create messy and toxic lead dust.
