Aero Bat Pac De-Sulfators-Totally Un-like Any Other "smart charger"
Make no mistake about this, true computerized electronic pulse sulfation is not like any other "smart charger/maintainers" that you see advertised or being sold locally such as at motorcycle stores or Wal Marts etc. If it doesn't say "electronic pulse charging" it probably isn't a true electronic pulse de-sulfator such as ours as they are rare in the marketplace partly because they substantially more expensive to manufacture but also due to their unique technology they have proven to be more difficult to market effectively.
However, when used properly they have proven to be highly successful against common (excessive) lead plate sulfation typically found in infrequently used batteries and/or those used in warmer climates. To be clear however, they WILL NOT fix a "shorted cell" situation nor will our line of Smart Pulse Chargers charge a fully dead or super sulfated battery. Totally "dead" batteries will need to be charged with a "dumb" analog charger first in order to bring the voltage up to an acceptable level prior to engaging our electronic pulse charger/de-sulfators.

In reality, often sulfation has advanced to the point that electronic pulse de-sulfation can't be successful and/or other problems exist such as the typical "shorted cell" which can't be fixed by electronic de-sulfation. Thus your only choice is to replace the battery. If in doubt as to your battery's overall condition or ailment, test your battery under load using a simple load tester and/or perform a specific gravity test of each cell by a battery hydrometer. You can use a (optional) mini-hydrometer tester which can be ordered and shipped with your unit, or (preferably) have your battery checked for "shorted cells" and/or excessive loss of reactive material (plates) etc. professionally by a competent shop. Occasionally you can distinguish "shorted cell(s) by cells by cells which do not "boil" when force-charged by typical shop charger. But with that said, the most common "quick test" method to check for shorted/bad cells is by the proper use of a battery hydrometer (available at discount and automotive stores everywhere) by experienced shop personnel.
Generally sulfation manifests itself as a sulfur insulation or coating (so to speak) which tends to keep a battery from accepting or effectively holding a charge across the board to all cells somewhat equally. Pulse De-Sulfation will not repair "shorted cells" and other maladies such as vibration damage and a battery severely weakened by un-attended sulfation resulting in excessive plate sloughing-off of reactive material (lead), etc.. Thus, we do not recommend you attempt to de-sulfate/charge any battery or a bank of batteries with containing any battery with these problems as you will be disappointed.

Heavily Sulfated And/Or Semi-Dormant Discharged Batteries
Unlike normal or "dumb" chargers, these units WILL NOT charge a completely dead battery (or a bank of batteries) if sufficient voltage isn't present to trigger the unit. If for any reason the subject battery is totally discharged or nearly so, it may be necessary to first "force charge" it with a regular charger at least for a short period, so as to provide some level of voltage present to initially "excite" or "turn on" the de-sulfator/charger. For example, the de-sulfator typically needs to see a minimum background voltage of 5v for the 6volt unit, 10.5 volts on a 12 volt battery, 22v for a 24v unit, and approx 32.5v for a 36v unit in order to begin its automated charging/desulfating process.
Once the battery us up to an acceptable level of charge (see above), AND it has been determined that it doesn’t have any bad or shorted cells (as indicated by the hydrometer etc.), simply connect the Bat Pac and let it go for a few days or longer. The green light should stay on steady for a time while the unit brings the battery up to proper voltage prior to beginning its de-sulfation mode. After the Bat Pac unit senses the battery has received sufficient charge, it will automatically switch to the de-sulfation mode indicated by the steady green light turning to a blinking green light. This could take a few hours or days, depending on how long it takes to bring the battery up to full rated charge. On a otherwise good but sulfated battery it should switch over within a few days.

The unit is charging when the green LED is steady, and pulsing de-sulfating ONLY when the green light is blinking

If the green light doesn’t switch from steady to blinking within a reasonable time or the time allotted in the formal instructions, check the battery again with a load tester or hydrometer as it probably isn’t a candidate for de-sulfation as it probably has one or more “dead” or shorted cells.

Once the unit has been hooked-up and has charged the battery sufficiently (typically overnight), it automatically switches to pulse de-sulfation mode and as indicated by a blinking green light. As a preliminary evaluation test however, after the unit has been hooked up for a hour or two, you can manually force it to go into the de-sulfation mode by pressing the mini black button and the green light should begin blinking if the unit has determined the battery will accept the pulse charging operation. You should then disconnect and then re-connect one of the leads and allow the battery to return back to its normal automatic operation.

IMPORTANT: Dead or excessively discharged batteries must be charged first by a different charger prior to using our units.

In-Use/Charged Batteries: If the battery has been in use and has been operating relatively satisfactorily, chances are it is already in somewhat of a charged state ready for the de-sulfator. After hooking it up initially, simply press the manual pulse button to "force start" the de-sulphation process manually to verify the de-sulfator recognizes the battery to be a satisfactory candidate. Then if you like, you can then temporarily disconnect the de-sulfator from the battery only to reconnect it again to allow the unit to function totally automatically where it will eventually automatically switch to its de-sulfaton mode on its own when ready.
Unique patent pending PulseMode creates high-frequency pulses that break down the sulphated crystals. The battery is then able to reach its full level of charge, without excessive heat generation common to regular chargers. Remember, if the green light isn't blinking, the unit IS NOT de-sulfating. If after a reasonable period of time the unit won't automatically switch to the de-sulfation mode OR you can not force it to by depressing the manual De-sulfation Button, the battery probably isn't a candidate for de-sulfation and has other problems.

Note: Typically even if left unattended for extended periods of time (months), and if used in accordance with directions, generally speaking water never needs to be replaced while batteries are being automatically maintained with Aero Bat Pac. The unit is designed to never "boil out" the electrolyte (battery acid).

The popular 12v units plug directly into a standard wall outlet (or extension cord) typically eliminating the need to remove the battery from its "in-use" installation location. The 24v unit has a 115v cord and is substantially larger/heavier than the standard 12v unit. Both units are "water resistant" but should be kept out of standing water and should be protected to some degree from the elements. While many aviation users keep the detachable ring terminal ends conveniently connected to their battery full-time and no damage has ever been documented to any on-board electronic equipment or avionics, when used on aircraft it is recommended all on-board avionics be shut down including various "keep alive" circuits during the on-going pulse de-sulfating process. Alternatively, ideally the ship's battery should be removed or disconnected from the aircraft just in case. In any regard make no mistake; we do not warrant any damage to outside electronic components should you elect to de-sulfate your batter in place.

The Underwriters Lab (UL) and CSA LISTED Aero Bat Pac has both Charge/ Power On as well as Battery Condition / Polarity indicators. The unit isn't designed for un-protected use outdoors. If used outdoors in potentially wet areas, it should be protected from rain and heavy dew etc.

6, 12, 24, and 36v units will typically reject* a "shorted cell" or junk battery while ensuring a full charge (and pulse De-Sulfation) to all others, including deep cycle marine, gel and maintenance free automotive types. See box below for more detail on the diagnostic capabilities of this unit. In some cases however, it may be necessary to charge a fully discharged battery with a normal or "dumb" charger prior to engaging a de-sulfator. It is unsure if a defective battery within a "bank" of batteries (such as a golf card) will negatively affect batteries down-line, so it is important that no defective batteries with "shorted cells" exist when charging banks of batteries such as typically found in golf carts etc.

The 1.2 amp charger function on the 12v unit operates similar to other automatic chargers, but may not initially charge a totally dead battery. Generally the de-sulfation process itself takes several days if not weeks (or longer) to remove significant sulfation deposits from G-35 aircraft battery plates. Typically the larger the battery and/or the more sulfation present, the longer it takes to de-sulfate. Pulse de-sulfation is a process for long-term preventative maintenance and is not a short-term quick fix. Most units come complete with a simple to use hydrometer type battery tester, quick connect terminal assemblies. Both Bat Pac units come with a 5 year “no hassle” warranty.

Typically, otherwise good but operationally non-functional heavily sulfated batteries can be restored to approx.70- 80% of original rated capacity if they have no other physical maladies such as a shorted cell or excessive plate "fall out" or deterioration etc. This unit will not repair shorted cells or physical damage to batteries and will not restore reactive material which has already sloughed-off to the bottom of the case. It will however, remove (and help keep from forming in the future), most problematic sulfation which has formed due to neglect or in batteries which have not been charged on a regular basis etc. Usually on batteries which are not used on a regular basis de-sulfation is necessary in order to keep batteries from becoming re-sulfated in the first place.

Aero Bat Pac De-Sulfator Automatic Diagnostic Capabilities
The unit has two small LED lights, green and red as well as a small black button. The red LED is simply a power indication light and should light up once the unit is plugged in to household voltage. The green light should glow steady once the unit is hooked up properly to the battery (red pos, black neg) AND if the subject battery is showing sufficient voltage to accept a charge (See Diagnostics above).
Once the unit has been hooked-up and has charged the battery sufficiently (typically overnight), it automatically switches to pulse de-sulfation mode and as indicated by a blinking green light. The better condition the battery is to begin with, the quicker it switches to pulse mode automatically. As a preliminary evaluation test however, after the unit has been hooked up for a hour or two, you can manually force it to go into the de-sulfation mode by pressing the mini black button and the green light should begin blinking if the unit has determined the battery will accept the pulse charging operation.

A "Quick Check" To Determine If Our Unit Has Switched Into Its De-sulfating Mode
If a battery is rejected by our units as “junk” or doesn't have sufficient voltage, the Bat Pack unit will never switch to the pulse mode as signified by a pulsating green light. Sometimes however if the battery is not fully discharged, you can “force” it into the pulse de-sulfating mode by clicking the manual pulse override button. If the green light starts to blink, it is a good sign the battery will accept the de-sulfation process. Typically, it will switch from “charge” to “pulse” after battery is fully charged or some 24-48 hours if the battery is salvageable. Temporarily disconnect a lead and then reconnect it to allow the unit to go back into its charging mode and to operate automatically again.
While some minimal charging takes place in the pulse mode, it is generally recommended to simply hook the unit up to the subject battery and then allow the unit to automatically chose it’s method of operation. If it doesn't switch to the pulse mode after a reasonable period of time (generally a day or two), you can attempt to charge the battery via a different "dumb" charger, but generally in these cases the battery should be considered junk and un-salvageable.

Note: The Pulse de-sulfation process can take weeks (or longer) depending on the level of sulfation and size of the battery etc. Typically the more plate area the longer it will take. G-35 aviation batteries should only take a few weeks to de-sulfate initially. If the battery doesn't respond in a month (or so) of cumulative pulse de-sulfation it is beyond help and should be replaced.
