Hagen Brothers farms,Goodrich ND | yes, the batteries are common units avalible at Interstate or other battery stores. You might just need to allow enough time for the batteries to recharge. leave the unit plugged in and remove all load for 24 hours. My 10 year old UPS ran dead when the power went off a couple nights ago in an ice storm.. It took a full 24 hours with no load before the internal battery recharged. seems OK now. |
