*NOTE: Charging rates below the battery's maximum capacity will extend battery life. A charge rate of 100A is recommended, though up to 150A is allowed.  After 3000 cycles at 100% depth-of-discharge the battery's capacity will be approximately 75% of when it was new.

**NOTE: altE strongly recommends staying within a temperature range 32 - 113°F (0 - 45°C) for both charging and discharging to prevent damage and extend battery life.

***NOTES for Cold Rated Batteries:

  • The 1800 CHLX heater is 96W while the 3600 CHLX heater is 192W.
  • Maximum of 4 batteries can be used in series or parallel, but not both.  The CHLX are programmed so that when they are in parallel or series, if one gets cold enough to start heating, all of the CHLX in series or parallel will start heating.  This is to prevent widely different power draws and states of charge in the battery bank when some are heating and cannot charge, while others are warm enough to charge.  As the communication between the CHLX happens through the power cables, if connected this way, this communication can not take place. 
  • In both batteries, the heater starts at an external temperature of 0°C (32°F).
  • Heating stops when the battery reaches an internal temperature of 10°C (50°F).  However, the battery will continue heating even after the battery reaches low temp protection release of 39°F (4°C).
  • Below an external temperature of -30°C (-22°F), the heat dissipation is too great to bring the battery up to temp.
  • When the batteries are on an AC charger, it takes about 2 hours to warm the battery from an internal temperature of -30°C (-22°F) to 10°C (50°F).
  • It will take about 1.5 hours to warm the battery from an internal temperature of -20°C (-4°F) to 10°C (50°F).
  • When the batteries are charging with solar, it might take a longer time, depending upon the charger output.

1)    Each battery must be individually charged to 14.0V before placing it into operation with other batteries. Otherwise, the batteries will independently hit ‘full’ or ‘empty’ and shut off before others in the same battery bank.

2)    Equalization charge must be turned off in your solar charge controller or AC charger. If left on, the equalization charge will raise the voltage too high, damage the batteries and void the warranty.

3)    Bulk/Absorption charge voltage should be set to no higher than 14.0V for a 12V system, 28.0V for 24V system, and 56.0V for a 48V system (and lower for high amp chargers). Going any higher risks one or more batteries automatically shutting off in a high voltage protection mode.

4)    Similarly, the ‘Low Voltage Cut-Off’ on the inverter should be set for no lower than 12.0V, 24.0V and 48.0V for a 12V, 24V and 48V system, respectively. Going any lower risks one or more batteries automatically shutting off in a low voltage protection mode.

5)    When turning on breakers to inverters, charge controllers, battery monitors, etc. connected to the batteries wait 45-60 seconds between powering up each device. The KiloVault’s battery management system has special circuitry to detect short circuits and protect itself. Many brands of inverters, charge controllers and battery monitors will present a very high but very brief surge that can be interpreted as a short. The KiloVault can handle one of these ‘shorts’ every 45-60 seconds.

Alternatively, in most circumstances all devices can be powered up at once but the batteries will go into auto-protect mode and turn off for 30-60 seconds but then restart normally.

6)    Be sure to tighten the battery terminals before operating. Failure to do so will lead to the terminals overheating, melting the case and potentially cause a fire.
