1994 Chevrolet Blazer battery drains

battery drains while is off for a few days

  1. Have the battery tested, if bad replace. I preemptively replace at 3-4 years.
  2. If battery is good, check for parasitic draw.
  3. If good battery and no parasitic draw you might consider getting a battery maintainer or driving the car more.

You might not be driving enough to fully recharge the battery when you do drive it.
