To check the batteries, you can either buy a load/test tool from Harbor Freight (cheap unit but does the simple task), or fully charge the batteries by leaving the shore power connected for 24 hours and then run a heavy 12V load like the slide motors, a 12V 55W automotive light bulb, or or an inverter running a 100W light bulb to see how many in/outs of the slide, hours on the light bulb before the battery runs down to around 11.5V under load. If the house batteries can power the slide for 3-4 in/outs or power the light bulb for 3-10 hours, then the batteries have a good amount of stored energy and need not be replaced. I would then check the current draw in the "shutdown" mode with an inexpensive portable digital voltmeter/Ammeter to make sure the current draw is less than 100mA (it should actually be in the few mA range) by disconnecting the + or - battery terminal and inserting the ammeter (using the 10A range to start with). If the current draw is too high, go for warranty service immediately.
