We have a used uninterrupted power supply for sale. The battery is in excellent condition. This thing is a beast with a monster battery for plenty of time to get things shut down for a power outage. You could even brew a pot of coffee and keep it hot for an hour and plug in your fridge if you had to. Send me a message with a telephone number so I know you’re a human being if you’d like more information. Will negotiate. Can take paypal payment and ship at your expense. Thanks for looking.
