Chapter 11 Battery Option 
CHAPTER 11 Battery System  
The battery available for the House is a rechargeable sealed lead-acid Gel type battery 12 Volt 
31AH. This type of battery is very dependable and safe. It can be repeatedly charged and 
discharged. This is an optional item needed only if you are at a location that does not have 
electrical outlets. 
Connecting 
The battery connects to the same connection as the power supply, to the red and black 
connector on the back of the House. 
How to Recharge 
Connect the alligator clips of the charger to the battery posts. Plug the charger into an 110 V 
outlet and the charger needle will go up to some level. The charger is an automatic type battery 
charger. This will recharge the battery full in 10 to 14 hours. This type of charger will not 
overcharge the battery if left "ON" indefinitely. Avoid leaving it charging for more than 5 days.  
Generally remove the battery from the charger when the charger indicates a full charge.

 Cautions 
Batteries are provided with a polarized connector to avoid connecting the battery backwards 
and damaging the circuitry. If these connections are disturbed, please be careful to observe 
proper polarity when reconnecting the battery. Use a digital voltmeter, if necessary to verify 
polarity of the battery and at the end of the connector of the battery. 
It is best not to allow the battery to go completely dead as this shortens the life of the battery 
and makes recharging more difficult. Fully charge the battery after each use. 
Important: Charge the battery to a full charge right after using the robot. Gel 
type batteries will be damaged if not kept fully charge at all times.
