I have a CPAP that runs on DC 24V 3.75A- can I use a battery setup that provides DC 24V 14Ah without damaging the CPAP? |

The voltage is okay, and assuming a sealed lead-acid battery, amps are fine, but the watt-hours -- not so much. Battery: 24v*14Ah=336 watt hours Load: 24v*3.75A = 90W Under optimal conditions: CPAP can run for 336Wh/90W=3.733 hours Not quite a full night's sleep. |
