gel batteries
22.2.1 General
Following completed evaluation and testing, recommendations for the 
setting of parameter 21 on RRs fitted with Hawker Evolution gel bat
-
tery have been prepared. There are also instructions for verifying and 
adjusting the set values.
22.2.2 Battery recommendation
Exide gel batteries (e.g. Sonnenschein)
In our tests of Exide gel batteries, we have not been able to make any 
recommendations for setting the parameters on any of our products. 
As a result, we do not recommend using this type of batteries.
Hawker Evolution batteries
For Hawker Evolution gel batteries, clear guidelines regarding their 
use exist. This is why we are able to recommend these batteries.
-The Evolution batteries have been designed for use in low-intensity 
applications. 
-The recommended use is one shift per day (max. 8 hours).
-Max. 6 days of use per week with an expected service life of 1,000 cy-
cles.
-Max. discharge level 70%
-The ambient temperature should be from +5°C to +35°C
-The battery must be charged using a Hawker battery charger with an 
EZ controller. Charging must be done according to the instructions 
supplied with the Hawker battery. 
-Typical charging time 12 hours
-Equalising charging is required after 6 charge cycles
-Discharged batteries must not be stored away. The maximum al-
lowed storage time is 2 month, however, charging once a month is re-
quired.
22.2.3 Battery installation
NOTE 
Parameter 21 must always be checked and adapted to the battery, 
which is installed in the truck. The parameter setting depends on the 
battery type, machine type and battery size.
