Mark, So, why do you suppose that your battery was Bulged? See N64KR at http://KRBuilder.org - Then click on the pics See you in Mt. Vernon - 2006 - KR Gathering There is a time for building and a time for FLYING and the time for building is over. Daniel R. Heath - Lexington, SC

The battery is a Power Sonic http://www.portablepower.com/items/batteries/SLA/1/Powersonic/PS-12180/PS-12180NB/SL105/35L105S3 PS-12180NB. This is a UPS (uninteruptable power supply) type battery and is optimized by a charge rate of 5.4A till it reaches 14.4 to 14.7 volts. Once fully charged this type of battery must have a charger that either shuts itself down or goes into a float voltage mode. A float mode for this battery is a constant charge range of 13.8 to 13.8 volts continuously. When held at this voltage the battery will seek it's own current level and maintain itself in a fully charged condition. I am running the John Deere dynamo system and this system emits a continuous charge rate of 14.5 volts. This extra voltage can not be tolerated by this UPS battery and I speculate that it heated the battery up causing the bulging of the side. There is a possibility, under these circumstances that the battery case could rupture/explode while in flight which would create unwanted circumstances. I promoted this as a good Sealed Lead Acid Battery to use in our aircraft. I have now flight tested this battery and DO NOT recommend it any longer. Mark Langford, I suggest you remove yours and replace it as well as anyone else who may have one.

Mark Jones wrote: > I have now flight tested this battery and DO NOT recommend it any longer. Mark > Langford, I suggest you remove yours and replace it as well as anyone else > who may have one. H. My flight test doesn't match your flight test. My battery is mounted on the cabin side of the firewall, and I think yours is on the engine side. I inspected mine today, and it still looks perfectly new. Of course mine might explode at any minute. Given that the engine side (on my airplane anyway) is about 80 degrees hotter than the cabin side (not counting radiation), I'd say I might have a bit of margin left in my case. Thanks for establishing the upper limit for me though, Mark! For now I think I'm good to go, but might look into a regulator that's a little smarter than the one I have now. I basically stripped the whole top off of mine today, removing cowling, forward deck/canopy, and aft deck, so I can do some overdue maintenance. It's supposed to be crappy for the next few days, so it's a good time for that sort of thing. Little stuff like moving the static port (again), adding a fuel totalizer, making the fuel system totally redundant, and mounting the auxillary display to my panel for my laptop. It brought out all the hangar hounds from around the airport for a look. "Field stripping" makes maintenance pretty easy. See http://home.hiwaay.net/~langford/05102208m.jpg ...

Geday Mark This is what happened to my battery also when the Kubota regulator failed (refer archives), I think as a result of overreving the dynamo. The Kubota dynamo revs should not exceed 4250. I then used a bigger pulley (about 4 1/2 inch dia) to slow it down and have had no further problems. I imagine the Deere is similiar. Hey, it could be worse.at least your battery buffered your avionics.

KR> battery had bulged
might look into a regulator that's a little smarter than the one I have now + Like most things, battery design has its compromises - electrolyte (gel) volume, plate area, distance between plates etc. These parameters obviously effect size and weight for a given AH capacity and the often ignored cold cranking capacity (where relevant). Some batteries are designed to efficiently "store" energy that is received and delivered at modest (charge / discharge) rates - units designed for Solar and UPS applications generally fall in this category and are very effective provided they are not subjected to high charge / discharge rates. The acceptable charge rate (in this case) is more of a trickle charge, but certainly not much over C/10 and the acceptable discharge rate is adequate to deliver the full (stored) capacity over a period of time. Whereas we can control the charge rate and solve most of the battery damage type problems, cranking an engine is very demanding in terms of current draw, if the battery is not designed for this, its life will be short. Subjecting the battery to a higher (than spec) charge (or discharge?) rate is more likely to cause damage from overheating, than high temps in the general environment. Steve Zambia
