The "D" cells in the Honda Hybrids are 100 amp drain rating with a 50 amp charge and 6 amp hour capacity. They are NiMH and discharge down to .9 volts. They will drain 100 amps for about 2 to 3 minutes before dead. But the computer limits the time to about 30 seconds at a time to prevent heating that can shorten their lives. The computer also limits charge usage to 4.5 Ah so as to enhance their lifetime. They are warrantied for 10 years and if taken care of should last 25 years. My current battery is 9 years old and I just did a reballancing on it and it looks good for another 9 years.

Practically, though, for most chemistries the higher the discharge current the lower the A-H rating. So manufacturers will throw in another spec, the length of time that the battery or cell takes to fully discharge. This is called the Rate, and the majority of small primary and secondary batteries will use the 20-hour rate. This means that the battery will supply the rated total amper-hours in 20 hours. If you use a battery rated 18 A-H the manufacturer claims that it will deliver 0.9 A for 20 hours. Detailed spec sheets may also state the rating at the 1 hour rate, which will generally be lower to much lower. Note that in order to test a bettery to see whether it actually meets ratings, you have to have a constant current load. With most batteries (but not all) this means that as the battery discharges you (or the apparatus) have to decrease the the load resistance as the battery voltage drops in order to maintain the current at a fixed value. The answer to the related question of when is a battery considered to be fully discharged is that for LeClanche and Alkaline the end of discharge voltage is 1/2 the rated "new" voltage. So for D-cells, 0.75 volts per cell. The cells are not totally dead at that point but if you had a current regulated load capable of going to to essentially zero ohms, my experience in another life where our business basically lived or died depending on whether batteries lasted long enough is that you would reach that point in about 20.5 hours. Give or take 15 minutes. I'm less certain of this as we just took the 50% or other voltage (we also used other chemistries) for end of discharge and designed around it but I think I recall that this is the voltage at which point the battery has delivered about 95% of its total watt-hour capability (when discharged all the way to zero volts).

  Does anyone know how to ship the BB-5590 Lithium batteries?  The postoffice will not allow me to ship them.

Any help with how to get 2 of them shipped would be greatly appreciated.

Here is what I found on the UPS site.  It looks= like I can't ship them unless I am a contract hazmat shipper.  This r= eally sucks!!!

 

 

Both rechargeable and non-rechargeable power sources, common= in computers, cell phones, cameras and other small electronic devices.&nbs= p;If dropped, crushed or short-circuited, these batteries can release dange= rous amounts of heat and may ignite, and are dangerous in fires. Speci= al regulations apply to shipping these batteries. Shipments requiring hazardous materials shipping papers are = accepted from contract hazmat shippers only, and certain lithium batteries = may not qualify for UPS service.

 

 

Here is what they have for Fed-Ex

 

= Packaging Requirements for Primary Lithium Batteries 

· Primary lithium batteries and cells must be indivi= dually packaged in fully enclosed inner packaging consisting of plastic bli= ster wrap, pasteboard or other fully enclosed packaging that will protect e= ach battery and cell from making contact with another lithium battery or ce= ll, or any item that is capable of conducting electricity, in order to prev= ent short-circuiting. Please note: Multiple batteries enclosed in a single = form-fitting "retail ready" blister pack are acceptable.

· Shippers are required to contact FedEx Express Dan= gerous Goods Administration at 1.901.4DG.SAFETY (1.901.434.7= 233) and certify that they comply with this new interim lithium ba= ttery and cell standard.

· We will accept shipments of primary lithium batter= ies and cells offered as "excepted" or nonregulated per the IATA dangerous = goods regulations with preapproval from FedEx Express Dangerous Goods Admin= istration. Contact FedEx Express Dangerous Goods Administration or your Fed= Ex account executive for complete details and procedures.

· FedEx Express Dangerous Goods Administration will = maintain an internal list of approved shippers. Recipients or distributors = cannot continue to ship primary lithium batteries unless they are on the ap= proved shipper list. Contact FedEx Express Dangerous Goods Administration o= r your FedEx account executive for details on how to be placed on the list.=

· The above requirements are in addition to the IATA= dangerous goods regulations and any other packaging or shipping requiremen= ts.

These requirements do not apply to rechargeable lithium b= atteries or lithium batteries contained in or packed with equipment.*
