This chart shows the
relationship between the number of steps climbed up and back down again and the battery
voltage on the Escalera. Notice that after you have climbed about 78 steps all the way up
and back down again the voltage begins to drop. It drops very gently losing about one volt
per flight of steps. As the battery voltage drops, the Escalera climbs slower and slower
and this gives the operator a good warning that he needs to recharge his battery.
Because of the energy efficient gearbox on the Escalera,
even with a totally dead battery although you may not have enough power to climb all the
way UP the stairway, you will always have enough power to climb back DOWN the stairway.
The standard battery included with the Escalera is a 17 amp per hour battery. It is sealed
leak proof battery which can be laid in any position and it can be shipped UPS.
