What’s Special About the Robot Window Cleaner Lithium Backup Battery?
The Robot Window Cleaner Lithium Battery is a 14.8V Lithium-Polymer rechargeable backup power source for the robotzoo Gecko, Gecko II, Glider, Glider II and Glider III window cleaners. The backup battery is an essential component for a robotic window cleaners.The battery is intended to provide backup power just sufficient to keep the window cleaner adhered to the window for up to 20 minutes.
They are a lithium polymer composition, which is light enough to be carried on-board the device, and powerful enough to drive the fan motor and provide sufficient suction in the case on interruption of the mains power supply.
These lightweight lithium polymer batteries need to be topped up in charge at least every couple of months to remain in good working condition. If they are allowed to drain below a certain threshold voltage, and then left that way for a period, then they will not be able to be charged back to their peak voltage again.
And since the backup battery is a safety feature, the window cleaners will not turn on unless the backup battery can provide a certain baseload voltage. If your robotic window cleaner won’t turn on, then replacing the battery will usually get it working again. We have tested these batteries on various types of robotic window cleaners and they work well.
Most models of robotic window cleaner will use the same type of rechargeable lithium backup battery, ie. 14.8V, 500-800 maH (around 10Wh) 4S-573040 (or similar) and, importantly, the same type of connector (XH2.54-3P). The batteries will fit into an enclosure which is usually around 20mm x 30mm x 50mm.
Replacing the batteries is usually easy to do. Just open the casing of your device by removing the casing screws, and you will see the battery, usually secured in its enclosure with double sided tape. Remove the plastic XH2.54-3P connector from the main board and peel the battery out. Use double sided tape to secure the new battery inside its enclosure, reconnect to the main board and re-seal the casing with the screws. Try to ensure that you don’t have any screws left over!
