I use a Battery Tender charger to keep my deep discharge 12V backup battery charged. This battery is used to provide me with a fan and a light, if needed, at home during a power outage.
After no problems for years the past few days the charger has started blinking its green light for a while, the steady green again after a few hours. The manual says the light blinks when the battery reaches 70% charge. This is occuring during a normal period of no power outages. So it seems to only be supposed to happen when charging. Normal charge condition is shown by steady creen light, which was the usual condition in the past.
Anyone familiar with this charger? Any suggestions? Just ignore it?
TIA
