Haze Gel VRLA Traction Battery 12Volt 31Ah EV

Haze 12 volt 31 Ah EV Pure Gel VRLA Traction Battery


When you're out in the heart of this sunburnt country, or on that unexplored river somewhere, what price would you put on the reliability of your power system? The ability to turn on the lights, start the motor, or simply to have a cold beer from the fridge?


For most EV applications GEL technology is without doubt the right choice, the price premium is easily off-set by the life and cycle expectations for this demanding application
subjected to high and low temperatures, unpredictable charging, daily cycling, probable partial state of charge discharges.


With over 20 years battery building experience, Haze have spent the past six years perfecting an economically priced gel battery for everyday use with proven German gel technology. The Haze gel battery range can withstand the rigors of demanding power applications such as

Quality and Safety


  • Utilising the latest in German technology
  • Thicker plates - Increased durability and deep cycle ability for heavy demand applications

Advantage of Gel Batteries


  • Ideal for repeat cycling daily use.
  • Reduced self-discharge
  • Excellent performance over long discharges
  • Good tolerance to higher temperature applications
  • Improved resistance to freezing
  • Suitable where mains power is unstable
  • Zero stratification due to immobilized electrolyte
  • No equalization charge necessary
  • Increased tolerance to poor charging parameters
  • Improved charge acceptance due to low internal resistance
  • High resistance to water loss with the right charging set up
  • Thicker plates for reduced grid corrosion and increased cycle life
  • Limiting design protects the positive plates to greatly improve cycle life
  • Ultra stable polymer separator with glass mat for increased performance
  • Full recovery from deep discharge, even when the battery is not recharged immediately.
  • High resistance to shorting due to superior mechanical strength of the polymer separator
  • Can be discharged even when full recharge has not been achieved, without loss of battery capacity
