12. Battery Temperature Compensation
Battery Temperature Compensation
The battery manufacturer will specify recommended float and equalize voltages at 25 °C (77
°F). Temperatures above or below the nominal 25 °C require a slightly lower or higher voltage
(respectively) in order to prolong battery life and ensure reliable operation. The ATevo Battery
Temperature Compensation option automatically adjusts the charger’s dc output voltage based
upon the battery temperature.
The ATevo Battery Temperature Compensation (or TempCo) option consists of a Battery
Temperature Probe (A10) and a cable to connect the probe to ATevo. The TempCo probe
contains a temperature-dependent resistor in an epoxy module that is installed on or near the
battery. This option can be ordered with the charger, or installed in the field later.

12.1. Installing the TempCo Option
Installing the TempCo Option
In overview, there are four (4) stages. The full detailed procedure is found in the next few
topics:
• Mount probe assembly (A10) on or near battery.
• Run interconnection cable from probe assembly to ATevo.
• Connect charger-end of cable to terminal block (A2-TB8) on ATevo Power Board.
• Configure ATevo to recognize TempCo option.
The TempCo probe (A10), or ‘puck’, is the same for all battery types and all ATevo models,
regardless of dc output voltage. Accessory part numbers differ depending on cable length.
PROCEDURE
PROCEDURE
1. De-energize and lock out all ac and dc voltages to ATevo.
2. Allow internal voltages to dissipate.
3. Remove safety shield and verify no hazardous voltages are present with a voltmeter.
4. Mount probe (A10) on a clean, dry surface on or as close to battery as possible.
