BATTERIES AND CHARGING SYSTEMS
There's more to charging batteries than just volts!
Selecting the correct charger type
Batteries are not all created equal and it is important to select a charger for the specific type and construction of battery that you will be charging not only to get the most life and duration from your battery, but also from a safety standpoint.
Charging a battery with too much current or at a charge rate the battery is not designed to accept can have serious consequence. The batteries used in aircraft are not the same as the batteries used in your automobile, lawnmower or your boat. The same is true for
Sealed Gelled, AGM, or Dry (no filler caps -electrolyte is "non liquid") Batteries like the ones used in most sailplanes. Only chargers specifically designed for these applications are listed here. If the charger is listed here then as indicated it is Ok for charging a battery of this type providing the battery is in good condition. If you have questions about other battery types and chargers available for these other battery types, please call or see the links to "useful information on this page.
Aircraft Battery Chargers
IMPORTANT!! All Aviation specific BatteryMINDer models are designed exclusively for use with either SEALED (AGM-non liquid) or Flooded (liquid w/ filler caps) as manufactured by Concorde, Gill and EnerSys (Odyssey, Hawker) for use on non-commercial aircraft specifically approved by FAA and/or PMA. ALL these types, regardless of manufacture are based on LEAD-ACID chemistry, NOT Nickel Cadmium, Nickel Metal Hydride, or any other chemistry-construction. If you have any doubt about the battery you intend to use with any of our BatteryMINDer products, please confirm these facts with the maker of your particular battery type.

BatteryMINDer®
Chargers by VDC Electronics, Inc.

 BatteryMINDer chargers are manufactured by VDC Electronics, Inc.  However, please note, just because it may be a BatteryMINDer Charger it may NOT be the correct model for your specific battery type! Please call if you are not sure what battery type you have or what charger is best for your use.

BatteryMINDer® Plus AGM/OPTIMA

Click image for more info
NOTE: Model 12118 AGM / OPTIMA BatteryMINDer PLUS® should only be used on AGM type sealed batteries, not “filler cap” liquid batteries, due to its special voltage settings. This unit is designed primarily as a maintenance charger for long term, safe storage charging of Optima and other similar AGM type batteries, not as a primary or general charging source.
1 1.0 Amp = Maximum current available if required by battery when unit is in maintenance mode. Charge voltage, 14.7; Float-Maintenance voltage, 13.4. If storing or in-season charging your battery, in higher than 77 degrees F temperatures, we recommend maintenance voltage setting of 0.2–volts lower, namely 13.2-V (Float). www.batteryminders.com tech support at (800) 379-5579 Ext. 206 (ET, M-F) MSRP $69.95.

BatteryMINDer® Aviation Specific Battery Charger Model 12248-AA-S2
BatteryMINDer Aviation-Specific 12-Volt 8A Charger-Maintainer-Desulfator-Conditioner Plug 'n Run Model


Click image for more info

VDC Electronics now has available a Plug 'n Run Aviation Specific versions of its 12-V Maintenance Charger - De-Sulfator - Conditioners. Designated as the 12-V model 12248-AA-S2 (Aviation Specific), it is similar to model 12248-AA-S1 except for its Plug ‘n Run feature, eliminating the need to set neither the output current nor battery type, before operating. This feature is of particular importance if any person, unfamiliar with the setting requirements, is involved in maintaining the battery.
The model include full-time pulsed de-sulfation circuitry designed to safely dissolve sulfation build-up on the battery's storage plates, restoring lost cranking power and extending life. Our de-sulfation method is fully automatic, does not use potentially damaging high voltage and is exclusively protected by two U.S. patents.
Presently only a small number of VDC dealers carry this -AA-S2 model.

Size really does matter!
Sealed batteries like those used in most glider applications are of a Sealed and leak-proof Lead Acid variety and require different charging methods than those used with NiCad (Nickel Cadmium) types.
It is important to keep Lead Acid batteries fully charged and to re-charge these battery types as soon as possible after every use. Unlike NiCad batteries, Lead Acid batteries do not have a memory so there is no benefit to deep discharging and in fact if completely discharged like a NiCad will in fact begin to internally corrode and eventually will fail. NiCad type chargers and those used for common household appliances are constant voltage and not suitable for Lead Acid battery charging. A proper SLA charger like the types shown here charge based on the battery condition and automatically sense battery condition to insure the battery is given a Bulk, fill and maintenance charge when connected.
A standard overnight recharge is normally recommended for typical lead-acid batteries.
This is based on a C/10 charge rate.  (C=Ah capacity of your battery)
Example: If you have a 12 Volt, 25 Ah battery then your charging rate is 2.5 Amps (C/10 = 25/10 = 2.5)
The Ah rating of the battery x 1.2 equals the amperes required to recharge, divided by the charging circuit, equals the amount of time (in hours) required to recharge the battery to 90%.
These times are basedon a fully discharged battery.
For 100% recharging, add 3 hours "float" time to the charging time.
If the battery is only partially discharged, the recharge time will be shorter.
Since the recommended voltage setting for each battery type varies, we follow the manufacturer's specifications to determine the correct voltage setting for each charger.   This will help to insure maximum battery life and will provide the most efficient recharging possible.
