Unimeter features battery monitoring, an hour meter, and programmable maintenance scheduling.


Unimeter’s Specific Instruction Display indicates the battery’s state of charge and action required by the Operator.

Do not charge (green)

Charging in the DO NOT CHARGE range is destructive charging. Destructive charging wastes energy, reduces battery life, and increases water consumption. When the DO NOT CHARGE indicator is illuminated, the battery has sufficient charge to complete at least one full shift.
Ok to charge (yellow)

The OK TO CHARGE instruction indicates the battery has sufficient capacity remaining to complete the present shift. This setting is programmable to enforce maximum discharge policies or to allow batteries to be charged without interrupting workflow. Charging in this range is constructive charging and produces good lifetime battery capacity. The OK TO CHARGE indicator is backed up with an optional 5-minute variable alarm.

Must charge (red)

Operating the battery until the MUST CHARGE instruction is illuminated produces maximum lifetime capacity, greatest number of shifts per charge, and lowest per ampere charging costs. Charging in the MUST CHARGE range is used when mid-shift battery changes do not adversely affect workflow. The MUST CHARGE indicator is programmable to maximize battery use to the specific requirements of the workflow. Once the red light is illuminated, a warning beeps every 5 seconds, advising the Operator in advance that he/she has 10 minutes of lift operation before "lift lockout" engages. The "lift lockout" cannot be bypassed or defeated. Note: Lift lockout is normally programmed to engage at 80% discharged.

Battery Fault Indicator

The Battery Fault Indicator advises the Operator that a problem is developing with the battery. Problems detected could be: cell failure beginning, problem with inter cell connector, broken battery post, bad SB connector, etc. Minor battery problems are detected before they become a major repair expense, and overall battery maintenance costs are reduced.

The Unimeter can be programmed with the number of hours before preventative maintenance is required for the vehicle. The number of hours is based on the method of recording time selected when programming the hour meter. When the preventative maintenance threshold is reached, the SERVICE indicator illuminates.

An optional "lift lockout", which cannot be bypassed or defeated, can be programmed to ensure the required preventative maintenance does take place at some predetermined time after the SERVICE indicator illuminates.

The Unimeter Programmer is used to program the Unimeter’s preventative maintenance settings.

The hour meter can be programmed to record time in two different ways. It can record time based on the number of hours the ignition key is on, or it can record time based on run time (when the truck is actually being used). An LED displays the recorded number of hours.

The Unimeter Programmer is used to specify the method of recording time.

The SERVICE indicator illuminates when preventative maintenance is due to be completed. This is based on the number of hours specified when programming the Unimeter.

The hand-held Unimeter Programmer is used to field calibrate the Unimeter to your charging and preventative maintenance policies. Exclusive microprocessor technology eliminates guesswork and allows settings to be quickly and precisely raised or lowered, regardless of the battery’s state of charge, facility temperature, or load conditions.

The Unimeter Programmer is used to program the Unimeter’s:

  • Battery voltage
  • Specific gravity for the OK TO CHARGE and MUST CHARGE battery states
  • Method of recording time
  • Preventative maintenance schedule
  • Lift lockout option
