Severely Discharged Batteries

WARNING

Risk of injury. Follow all Warnings and Safety Precautions.

For a battery to be indicated as "severely discharged", the resting voltage must be less than 11.6 V.

WARNING

Batteries that have a light yellow visual indicator do not have to be tested or charged. Jump starting must not be used!

There is a risk of explosion during testing, charging or jump starting.

These batteries must be replaced.

Caution

  • Severely discharged batteries freeze earlier.
  • Batteries that have been frozen must no longer be used.

Note

  • Severely discharged batteries in vehicles must be replaced prior to delivery. Pre-existing damage cannot be ruled out.
  • Batteries which have not been used in driving operation for a long time, for example vehicles in storage, discharge themselves.
  • For severely discharged batteries, the electrolyte consists almost completely of water, because the acid portion has been greatly reduced.
  • Severely discharged batteries become sulfated, meaning all the battery plate surfaces become hardened.
  • The sulfating process may be largely reversed if a severely discharged battery is recharged immediately.
  • If the battery is not recharged, the plates will continue to harden, and the ability to accept a charge will decrease. This results in reduction of battery performance.

Check the battery resting voltage.
