3.2 Battery Back-up (Optional)
The SL730 series has the capability of using a battery back-up system.
The battery should be conditioned before being used for the first time. Battery conditioning
involves removing all the charge from the battery. Batteries should be conditioned regularly.
Condition a battery when the device is stored for long periods, or when the charge becomes
noticeably shorter.
Follow the steps below to condition a battery:
1. Disconnect the battery from the light.
2. Attach the battery in need of conditioning to a suitable electrical supply.
3. Charge the device uninterrupted for up to 10 hours.
4. Disconnect the electrical supply and re-attach the battery to the light, allow the light
(while disconnected from its primary power source) to run on the battery until it
shuts off.
5. Charge the battery until full charged again.
6. The battery is now conditioned.
Batteries can deteriorate over time, meaning a reduction in their performance.
To check the performance of a battery, follow the steps below:
1. Charge the battery uninterrupted for 10 hours.
2. Disconnect the mains supply to the light and allow it to run on the battery until it
shuts off.
3. The operating time of the light reflects the condition of the battery. If the operating
time is significantly lower than when first purchased despite conditioning it, you will
need to replace the battery.
