What does Desulfation mode mean on a battery charger?

What does Desulfation mode mean on a battery charger?

The Battery Sitter’s unique automatic desulfation mode works like this: Once the Battery Sitter determines that the battery is sulfated it applies a voltage of up to about 20V at a controlled low current for a maximum period of 2 hours, to recover the battery to the extent that it can again accept a charge using the …

How long can a Mercedes sit before the battery dies?

“For BMWs and some Mercedes, it’s possible for a battery to die in two weeks,” says Patrick Brown-Harrison, instructor at SAIT Polytechnic in Calgary.

How do you extend the life of a dead battery?

Check out these tips to help extend the lifespan of your car battery.

  1. Limit short rides.
  2. Keep your battery tightly fastened.
  3. Turn off all the lights when you exit.
  4. Control the corrosion.
  5. Test your battery often.
  6. Don’t use electronics while idling.
  7. Care for your whole car.

How many days can a car sit before the battery dies?

When stored properly out of the car in a secure place, a detached car battery has the chance to last up to six months. Just like any other car battery, it will need charging, but not as often as if it were attached. Giving the battery a charge around every 12 weeks is a good rule of thumb.

Does charging car battery extend life?

If your battery reads at least 12.4 volts, it is sufficiently charged and should continue to hold a charge. If the reading is below 12.4 volts, the battery may be able to accept a recharge. Extending the life of your car battery comes down to proper care.

How is the desulfation rate of a battery determined?

This is what desulfation (desulphation)is about. Batteries are subject to an internal discharge, also called self-discharge. This rate is determined by the battery type, and the metallurgy of the lead used in its construction.

How long can a lead acid battery last?

Sulfation is not the only aging mode in lead acid batteries, so while desulfation may extend the life, it will not do so indefinitely. Last car battery I had lasted 8 years, but after that time it was internally distorted, and desulfation would not extend its life further.

How does a desulfator work on a battery?

The good news is that usually sulfation can be reversed by using a specialized kind of battery charger called a desulfator that sends pulses of high current through the battery at preset intervals.This breaks down the crystallized lead sulfate on the lead plates and the battery’s capacity is restored.

Is there an alternative approach to desulfation in batteries?

An alternative approach is resistive based and was discovered accidently (by the author), and is still not totally understood.
