Project: BatDLX
Date:January 2010

Note: This project has been superseded by Da Pimp which can desulphate, test and charge batteries of different voltages.

Summary:

BatDLX is a second generation battery desulfator. It is designed to be used with 12V lead-acid batteries, but it also works with 6V and 8V types. This device can restore batteries which have been sitting without a charge for extended periods of time.

Desulfation removes sulfur crystals that have formed around the lead plates. On a 12V battery sulfur crystals begin to form when a battery is stored at a voltage of less than 12.3V. These crystals are undesirable as they cause resistance within the battery which eventually leads to a battery being unable to pass current (a dead battery). Desulfation breaks the crystals by emitting a high frequency / high voltage / low power pulse which creates a resonance inside the battery.

BatDLX has several features which are not found on other DIY and commercial desulfators:

open source design (schematic, bom, gerbs, and source)
4 line text display showing battery voltage, temperature, and pulse strength
wireless data logging ready (xbee devices not included)
high quality clear pelican case enclosure for safe transport

Video Tutorial (How to Connect a Desulfator):

Usage:

run with case partially open to avoid overheating
black desulfator lead goes to battery negative
red desulfator lead goes to battery positive
recommended chargers are:
- 500mA - 1A, 12V wall wart
- solar panels with charge controller set at 14V
- car battery chargers
- RC car battery chargers (min 300mA max 1A)
connect charger in parallel with desulfator
