14 Volt Gel Cell?
Does anyone know where I can purchase a 14 Volt gel cell battery. I
know I can wire 2 or more in series to get 14Volt,(12 + 2 or 6 + 8 etc..) but I thought someone might know where you can purchase a single 14V battery. Thanks in advance. |

In the 25-odd years I've been in soaring, I don't think I've ever seen a 14-volt gel-cell battery that wasn't either a twelve and a two or two fours and a six. That's the way I've always wired them together. One useful bit of advice I've had on making them was to stick with cells of the same manufacturer and similar amp-hour ratings. Bob K. |

If you want to play with rechargeable lithium-ion cells, each cell is 3.5V so four of them are 15V. Lithium-Ion polymer cells are becoming available but they are more expensive than lead acid.

Joe,
Why do you want 14 volts...Most radios have a 12 volt regulator that drops 14 volts to 12 volts...I for years used 14 volts only to find out is was not required. Have used 12 volts with no problems since... Sam Fly Joe Allbritten wrote: Does anyone know where I can purchase a 14 Volt gel cell battery.

Never seen one, but I'm curious about what you want to power. -- Change "netto" to "net" to email me directly Eric Greenwell Washington State USA |

I have combinations or 4V(2) +6V or 12V +2 V batteries to get you to
14V.........but honestly, I sell these because some still think because their radio says 13.5V or 14V input they need this combination.....they don't, I have run everything from Radair's and Terra's to Dittel and Becker's with straight 12V batteries...these along even with GPS, Ipaq's and flight computers...they all run just fine with 12V Battery supply (which BTW will give you better than 13.5 volts on a full charge). feeding your equipment on 14V set-ups will work just fine too....everything "glows" a bit hotter and is happy....but your equipment will also run well below 11Volts, some radios now even down to near the 9V range. Also when you feed higher voltage the current drain will typically be higher so the mA's are going away faster.....you trade Volts available for Volts used......better choice is to make your lead and acid do the job at 12V supply.it's simple.it works fine...and you won't be searching for battery combinations to fit.... tim Wings & Wheels www.wingsandwheels.com "Joe Allbritten" wrote in message om...

Er,... the terminal PD of a fully charged lead acid cell is 2.2V, so 6 of them in series results in a battery PD of 13.2V. As the cell discharges the PD will gradually fall to some value under 2V (how fast and how long this process takes depends on the rate of discharge and the relative "health" of the cell. So you may end up with you battery actually providing less than 12V for a good part of the time it is in use. I suspect that manufacturers put 14V on their kit to get across the point that is well able to withstand the PD of a fully charge gell cell battery. Rgds, Derrick. |

Derrick, Sam, Tim, Others Thanks for the reply. The reasons I think I need 14VDC a 1.) That is what I received with the glider when I purchased it 2 years ago. ( 12 +2) 2.) The radio spec sheet calls for 14 VDC. It even states if you put this in a 28VDC aircraft, purchase the 28 to 14 VDC converter. The radio is a IImorrow Apollo 704. I am afraid to try 12VDC without consulting directly with the manufacturer. Reason being that if the voltage is below what it is designed for, some electrical/electronic parts will increase the current draw (amps). Excessive current loads can very damaging to electrical/electronic devices. I know it will burn up motors etc.. but not completely sure about electronics.

Joe Let us know where you find a 14v charger. TIA, Frank Whiteley Frank, I recieved one with the glider. It doesn't state the Mfg. but it does have a Part number, RR14650A. It is a smart charger just for 14 V gell cell packs. I have seen it at one of the websites that sales soaring supplies. If I figure out which one, I'll email you. Joe |
