Jim:
The 12 volt DC lead-acid batteries employed in most readers' vehicles, power storage systems and backup supply systems are expensive, have finite life spans and are a critical link in the timely operation of equipment required to respond to short term and long term grid-down situations. Aged batteries become unreliable, but are difficult to keep in a state of readiness and when deemed "spent" their replacement puts a drain on already limited financial resources.

Most people have battery chargers and the know-how to use them in an effort to keep older - or infrequently used - batteries in a charged state so they can be relied upon when needed. This is, however, time consuming and the unpredictability of battery depletion, through sulfation and other age-related deterioration, makes it difficult to keep your batteries in a constant state of readiness in a cost-effective manner that is not manpower intensive.

If a battery has reached a truly terminal stage of decay, such as failure of inter-cell connections, lead plate breakage or separations and similar situations that require mechanical reconstruction, then the battery should be recycled - it's beyond repair by ordinary mortals. But if the battery is mechanically viable and just badly aged, there is a very good chance that it can be brought back to a very useful state with a device that is relatively unknown but commercially available. I will not claim that it can be made as good as new, but my own results were very satisfying.

A neighbor of mine - a Ph.D. Chemist - came across, researched and subsequently purchased a device known as the Renaissance Charge Rejuvenator. He has already brought a dozen lead-acid 12V batteries back from near useless states. I borrowed the 'Rejuvenator' unit, and attached it to three different 12V lead-acid batteries of my own over a 4-day period. In each case the battery, which had previously been unable to retain a decent charge, was "brought back to life" and held a good charge making it usable for employment as a car battery, a source of energy in an inverter set-up or other traditional arrangements. The Rejuvenator works best if you use it repeatedly, drawing down the battery between applications. For my own batteries, I used the unit until it indicated "done" (green light), then I placed a load on the battery and drew it down to about 11V, gave it a rest period of about 8 hours and then ran the unit through another cycle to charge it back up and apply a "second dose" of the unit's proprietary repair process.
The Rejuvenator is not exactly cheap at $200 (delivered) but if you bring two "mostly dead" large capacity car batteries (or just one heavy duty tractor battery) back to useful life you've pretty well paid for the unit and after that everything is free. You might consider splitting the cost with a good neighbor or two.

I submit that readers would be well advised to do some research and consider purchasing one of these units to extend the life of the many batteries they already have in use, in order to avoid the high costs associated with replacement. I was stunned when I counted and realized that I have fourteen 12V lead-acid batteries on my ranch. Just as an aside, I have no vested interest in the company that makes the units, and will receive no compensation if this recommendation should result in sales for the Renaissance-Charge Company, though it couldn't hurt if you mention that "Ted from Careywood" sent you. They may be inclined to give some sort of small discount, though I have no control over that. In any case, the cost/benefit analysis seems to make it a good deal, especially for those who use lots of battery banks to avoid dependence on the electrical grid. Best Regards, - Ted

Anyone interested in cost sharing on one of these units?? If so, call and we can discuss the possibilities.
