We’re excited to introduce the newest innovation in battery technology. Introducing, Bolt Ultra 100Ah 12V Advanced Silicate-Salt Battery. These units are specifically designed for customers living in more extreme climates, wether that is extreme cold or extreme heat due to their better performance than VRLA counterparts at high temperatures and in cold environments.

Customers who live in more extreme climates, wether that is extreme cold or extreme heat love these units because they work much better than their VRLA counterparts.  In very cold or freezing environments they continue to perform 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.   

Bolt Ultra 100ah General Features:

  • Non-corrosive plates, electrodes, joints, and connections—allow battery a longer lifespan while retaining charging cycles
  • Functions in extreme temperatures between -40°C and +70°C
  • Performs extremely well in warm climates. 
  • Up to 2200 charging cycles when using 50% or less discharge. The battery can be 100% fully discharged without damaging the battery, however, it is recommended that it is charged immediately after high discharge to prolong the battery life and save charging cycles.
  • 50% higher specific energy density than the VRLA battery
  • Low internal resistance of 2Ω to 5Ω milliohm compared to 25Ω milliohm 12v lead acid battery 
  • Exceeds international storage capacity standards by 1.75 times and international recharge acceptance capacity standards by 2.68 times
  • No separate enclosures, ventilation, or cooling systems required -- saving on installations, maintenance, and energy costs
  • Lifespan up to 15 years: 4500 - 5000 cycles for certain applications

Bolt Ultra 100ah Batteries are 100% Recyclable and Green!

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 used as a fertilizer. The recycling of the lead becomes much easier and environmentally sound because the electrolyte does not degrade the plate and create toxic lead dust. 

Battery Charging

  • Since the charging ability of the Bolt Ultra is quite strong, it can adapt to constant voltage or constant current charging with minimal effect.
  • 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 and can 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 become 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 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. The manufacturer advises the end user to charge the battery immediately after high discharge to prolong the battery life and retain charging cycles.
  • It is recommended to not exceed 90% discharge for a longer battery life.

2years and it is amazing.. freezing to hot

I have had mine for two years and it has worked year round with solar panel and a small load constantly. It’s work flawlessly in 0 f degrees and in 100 + f degrees. No worry of damage like lithium also doesn’t need a load balancer… love this. Lost some Trojans from cold weather for my house, will replace with Bolt batteries

seems to hold power

It took a long time to discharge with multiple devices hooked up. I believe the two batteries I got will get me thru a power outage. I am considering another for the price. JIC!!
