13.1.1 Battery recommendation
Exide gel batteries (Sonnenschein, for example)
In BT's tests with Exide gel batteries, no recommendations were
obtained for parameter setting on any of BT's products.
BT does not therefore recommend these batteries.
Hawker Evolution gel batteries
After carrying out trials and tests, there are recommended parameter
settings for RRE with the Hawker Evolution gel battery. There are also
instructions for verifying and adjusting the set values.
These are the batteries that BT recommends.
There are clear guidelines on how to use Hawker Evolution gel batter-
ies.
- Evolution batteries are designed for low intensity use.
- Recommended use is one shift per day (a maximum of 8 hours).
- Weekly maximum is 6 days per week, with a limit on expected
service life of 1000 cycles.
- Maximum depth of discharge is 70 %.
- The ambient temperature should be between +5 °C and +35 °C.
- The battery should be charged with a Hawker battery charger
complete with EZ control. Charging must be performed in line
with Hawker's instructions.
- The usual charging time is 12 hours.
- Equalising charging is required after 6 charging cycles.
- It is not permitted to store discharged batteries. The longest per-
mitted storage period is 2 months, but this must involve charging
once per month.
