What Happens If Battery Water Is Low (Tips & Fixes)
When your battery water is low, the electrolyte concentration inside the battery gets all wonky. This lovable mixture of sulfuric acid and water is responsible for generating electricity. The low water level, however, causes the lead plates to corrode faster, leading to sulfation and an inability to charge, store, and discharge power efficiently.
Thermostat Says Low Battery Even With New Batteries (Fix)
Usually, your thermostat will notify you with a "low battery" message on the display when its batteries are near depletion. The "low battery" notice is to warn you that you have to replace the thermostat''s batteries before the power level is so low that the thermostat loses some of its functionality. But why are you
