John Bedini has given a gift to the world that can restore old, discarded, sulfated lead acid batteries.
If a lead acid battery is sulfated from normal use, it can usually be restored with this invention. One day the boat sank in a storm in salt water and the batteries were drained to absolute zero volts.
In the very top picture of this page, you see a simple lawn mower wheel with cheap ceramic magnets hot glued onto it. The front panel connections allow for easy changing of batteries and monitoring of the system status. On the back side of the control panel is a small blue jumper which allows quick attachment of various resistors in series with the potentiometer for experimenting purposes. This system can be shown to produce more energy on the charging side than is required to drive the motor.
You’ve just fired up your old PC, the screen comes to life with the usual BIOS messages and memory count. At least the PC still works , but the last message is a sure sign the CMOS battery has died and needs replacing. The CMOS battery is responsible for supplying backup power to the CMOS Real Time Clock (RTC) which stores date, time and hardware settings such floppy drive type, hard drive parameters, memory, cache settings and various other chip-set settings for the BIOS.
NiMH (Nickel Metal Hydride) rechargeable: Similar to NiCd but without the environmentally unfriendly cadmium. Any light corrosion around the battery area can be cleaned off with methylated spirits also.
Inspection: Check the condition of the copper tracks around the battery and nearby components. DIY external battery holder using 3 x AAA alkaline batteries:  Make your own external battery using AAA batteries. CMOS backup Capacitor: Rather than using a battery, these heavy duty capacitors can be used as an alternative. Using CR2032 button battery: You can also try hooking a up a 3v CR2032 lithium battery and holder connected to the external battery connector pins.
Some PC mainboards require a jumper to be moved to switch between an internal or external CMOS battery. Dispose of old NiCd, NiMH and lithium batteries correctly to reduce pollution to the environment. This 286 PC motherboard is nearly 25 years old and in perfect condition due to the original external lithium battery fitted.
If you’re lucky, your retro PC mainboard has been fitted with an original lithium external battery.
The original Dallas DS1287 was one of the most common RTC chips used and can be replaced with the newer DS12887 which can found on eBay HERE. Some RTC chips are soldered directly the PC mainboard which makes them more difficult to replace. De-soldering all these tiny pins can be tricky work and without the right equipment and it’s quite easy to make a mess of things and ruin the board. Equipment for desoldering the RTC: De-soldering iron, examination glasses, screwdriver and solder.
Often a couple of pins always cause trouble where the solder has not been removed properly,  so these will need to be reworked with new solder and sucked clean again. I strongly recommend using a DIP-24 socket before fitting the new RTC chip as this will make future replacement considerably easier. Replace the chip with the same part number where possible, otherwise use the nearest equivalent.
Lithium 3 volt button batteries have been used for CMOS back up since the mid 1990’s starting in late model 486 PC mainboards. The most common is the 3 volt lithium CR2032, but I have seen larger CR2430 lithium button cells used on some Compaq PC’s. The CR2032 button battery has been used since the mid 1990’s t for PC CMOS batteries. CR2430 button batteries are occasionally seen in propriety motherboards such as this Compaq Pentium III. I have a CMOS battery problem with my old HP-DC5000, with motherboard P4SD: the CR2032 batteries, where the original one had a lifetime of more than 7 years, are now empty within one or two months (I already replaced the battery 4 times), unless the power cord is never unplugged.
Probably worth a try doing that… or alternatively a 3 x AAA battery pack may do the job as well.


I’ve encountered some newer motherboards that still give a CMOS battery error even with new CR2032 button cells. A homemade coil of wire and a couple basic pieces of electronics are added to make a radiant energy generator. The third photo shows the back side of the control panel where the 5k potentiometer, jumpers and electrical connections are mounted.
A neon lamp shows if the charging battery suddenly gets disconnected, which would destroy the transistor. You must give it a little push to get it going, but then it will spin up on its own and self regulate its own speed based on the size and charge status of the batteries being charged. This triggers the transistor to turn on, allowing power from the run battery to flow through the secondary coil. Below are a couple photos of a box fan frame used with the SSG to blow air while charging batteries.
For more detailed information and help with construction, see the Yahoo Group Bedini_Monopole3. Without a working CMOS battery all the BIOS settings including time, date and hard drive parameters will be lost when you turn off the PC.
They are rechargeable 3.6 volt type batteries which are recharged each time the PC is powered on.
If the battery has hot melt glue holding it to the board, then break the glue bond by rocking the battery back and forwards a few times.
Attach this to the external battery connector on the motherboard, but you’ll need solder on a 4 pin plug and lead. But instead of soldering them onto the mainboard as they orginally were, they can be mounted externally, thus reducing the chance of corrosion ruining your valuable mainboard.
The board will probably have survived intact without any of the corrosion associated with a typical soldered on type battery… and as a bonus, finding and fitting a replacement external battery is dead easy. They are quite reliable and can have a long life span, often lasting 10 to 15 years before the internal battery finally fails. The old chip can easily be lifted out using a flat screwdriver and replacement pressed  back in.
They will need to be de-soldered, which can be difficult without proper de-soldering equipment, but it’s also possible to leave them in place and re-power the RTC using an external battery.
Release and loosen any stuck pins with a screwdriver before attempting to lift the chip out. Make sure the chip goes in the right way around, there’s usually a marking showing the correct orientation. The most common button battery used is the CR2032 and is still used in modern desktop PC’s today. The CR2032 is widely available at supermarkets, department stores, markets & online sellers and only costs a few dollars. I’ve read in some websites that the CMOS chip can accept a voltage range of 3-6V and that some people place a hefty 6V onto it without any problems.
So I suspect a defective component on the motherboard draws too much current when either the PC is unplugged or when there is a power outage in the house. Check the motherboard for dust and cockroach or mouse poo which might be causing a short circuit.
If disposed of improperly, they can end up in the land fill or rotting away in someone's back yard. The Bedini SSG (Simplified School Girl) motor will break up the sulfation on the battery plates and recharge the batteries. Two such batteries that had a charge of less than 2 volts each are now powering my electric boat motor.
The first three are the simple circuit and the last one is a more complex but higher output version. The magnetic field produced in the secondary coil gives the wheel a small boost on its way past the coil. They have a life span of 5 to 10 years depending on the amount of use, environmental conditions such as heat and humidity and the quality of battery. Notice how the corrosion is spreading to nearby components and ruining this 386 motherboard. White vinegar also seems to work quite well as it neutralizes the alkaline battery leakage.


This is great idea, when the mainboard doesn’t have an external connector for lithium batteries. RTC chips do not leak and PC mainboards equipped with RTC chips are usually in good condition as a result. A professional de-soldering iron with a vacuum pump is the best way to remove the RTC chip.
With a good de-soldering job, the old chip should virtually fall out by itself, but more often it needs a little assistance to be freed from the mainboard.
The old battery can be removed often without any tools, however some battery holders may require a small flat screwdriver to remove the old battery.
If anything, keep the voltage above 3 volts for best results and most importantly make sure polarity is correct. In many cases, the battery will actually gain more potential, usable energy than the day it was sold.
The first photo shows the whole unit housed in a homemade wooden box built with dowels and glue.
Old NiCd and NiMH batteries are notorious for leaking corrosive substance over the motherboard which can ruin it forever. SMD resistors and copper tracks are being eaten alive. Check the hot melt glue between the battery and motherboard.
After doing this rinse the area with distilled water and soak up any remaining water with tissue paper and then let dry. Put one probe on a screw pad (or another part of the PCB that’s clearly ground) and the other probe on either of the external pins. I need a four-pin wide connector for my 486 motherboard, but every battery pack I that I find has a different connector or no connector at all. My first idea was to replace the motherboard, but I realized that an appropriate MB is not easy to find, nor cheap. After some time and many cycles with the Bedini charger, the batteries are now better than new. Holes were drilled through the wood to the inside where all electrical connections are safely tucked away.
Both were found in the dump and are now doing well again after being restored on the homemade radiant energy charger shown on this page. Incidentally, some original mainboards came with 4.5v external lithium batteries installed. Some later 486 boards have a button battery stenciled on the circuit board therefore may accept button battery holder soldered on. Where there is zero resistance, this is most likely the negative (-) terminal for the battery. At this stage, the radiant energy enters the system and is dumped through a diode into the batteries to be charged.
To charge six volt batteries, simply hook them up in series to make twelve volts and charge them. I wasted no time and removed the battery and cleaned the motherboard where damage was evident.
My problem now is: I cannot find an external CMOS battery connector nor a related jumper on the MB. 1.2 volt NiCad batteries, connected together to make 12 volts have also been charged with this circuit. These will probably last 3-4  years before corrosion sets in, so mount these battery packs using velco tabs well away from the mainboard. What are your thoughts about removing the CR2032 battery and soldering the + wire of the homemade rechargeable battery system directly to the battery socket + connector, and the – wire to any ground connector on the MB ?
Think of old batteries in remote controls and what happens to those.  3 x AAA battery holders can be picked cheap on eBay HERE.
