Optima Red Top Group Size 34/ 78 Battery
Model:  34/78, Dual terminals (top posts, female side threads)
Rated 1000 CA, 800 CCA, 100 RC, Testing at 760+ CCA by Midtronics EXP-800, 950+ CCA by Live load Snap-On MT1590/ MT1560 carbon pile
Part Number 8004-003 / 9004-003


The bid price is for one unused boxed battery, no accessories, factory seal broken for charging & testing


This is a high current, vibration resistant, starting battery with tapered SAE terminals, (+ on the top left, - on the top right front), and recessed threaded GM-type side terminals.  Using high purity lead and spiral wound absorbed glass mat, (AGM), technology, Optima batteries typically achieve twice the cycle life of a normal flooded plate lead acid battery.  Replaces:  8004-003, 9004-003, 27990, 34-78, 34/78-980, 78DT, RED34/78, SC34U, and N9934/78RED.  This battery is intended for starting and not deep cycle performance;  use Optima Yellow or Blue Top for that service.

Condition: 

New, in-the-box (suitable for individual shipping), old stock, unsealed for charging and testing.  This was manufactured in Dec-07;  Optima states there is no expiration date for Optima Red Top batteries.   While unused, this battery has had the wrapping pulled away from the top terminals for charging and testing.  Because of the high current testing, the SAE tapered posts may have marks or pits from the charging and testing clamps but will in no way affect performance or attaching cables.


Testing:  These have been tested using:
* Midtronics EXP-800 deep scanning battery tester which gives a very conservative CCA rating, (printed individual test results are included with each battery),
* Snap-On MT1590 or MT1560 carbon pile tester, standard.  This is the standard live load test run on the freshly charged battery at one half the CCA Amp rating for 15 seconds at a minimum of 9.6 V at 70 F.  The carbon pile test is generally repeated after a few minutes to ensure no surface charge influence and assure good recovery, and both results are noted with each battery.


Buyers are welcome to drop by to witness testing.  Bring your own equipment if you like and tests can be run using it, too.


Warranty:
45 days from the date of shipment, provided by Seller.  Replacement with battery (of equivalent or better EXP-800 measured rating) or full refund less shipping upon return of battery to Seller.  Buyer pays all shipping.  Battery performance to be measured in accordance with Optima's standards using a standard carbon pile tester or Midtronics EXP-800 conductance battery tester.  The rating used for warranty comparison will be either the EXP-800 measured CCA or the carbon pile measured CCA associated with this eBay description at the time of sale. Originally, this Optima battery carried a 3 year free replacement warranty.  However, Optima does not honor a factory warranty for batteries sold on eBay and is thus not transferable and is likely not valid.  Seller is not an authorized Optima dealer.  For a warranty claim offered by Seller, email Seller for return authorization prior to returning.

Rating as stated by Optima.  This is not a guarantee of attainable performance.

This will ship by UPS listed daily rate, (this is a slightly discounted), + $4.40 (had been $3.00, but eBay is now charging their commission on    shipping so the $1.40 increase is for that recovery), from zip code 46304.  Seller does not markup UPS shipping cost and Seller pays the   UPS pickup fee.
Local pickups and payment are welcome.  Location is about 12 miles north of Valparaiso, Indiana and 3 miles south of Lake Michigan.
Shipping to USA and Puerto Rico only.  While it would be nice to help the USA's balance of payment, sorry, but UPS charges sooo much for
    shipping to Canada or Mexico to make it cost prohibitive.  (Like $100+.)  USPS is used to Puerto Rico, and expect costs to be
    approximately $53.  The eBay shipping calculator will show a UPS cost of more than $100 to Puerto Rico and this is one location where
    USPS is lower.  Seller can work with you if you have a lower shipping alternative.
A NOTE ABOUT COMBINED SHIPPING:  This refers to combining more than one purchase into one box.  If it were two of these Optima
    batteries, that would push the boxed weight into the 80+ lb overweight limit and the shipping would cost even more.  Savings would occur if
    the second item were small enough to fit into the Optima factory box and still weigh less than 80 lbs.

Performance may well improve with the first few deep cycles of use.  It may help to run the battery thru a deep discharge followed by slow recharge when first put in to use.  If the battery temperature exceeds 120 F or vapor is seen at either of the two battery vents, stop charging and resume once the battery has cooled.  Pulsed charging can help, too, and the charge voltage should not exceed 15.6 V if rapid charging and 15.0 V if normal charging.  Keeping the battery fully charged will lengthen its life and reduce sulfating.  Never allow the resting potential to fall below 10.5 V.


Desulfating every few months may help maintain performance for this as it will for most other lead acid batteries even if the battery is kept near full charge.  Often the CCA will increase, the Voltage will remain higher over time, and charging temperature fall.  Useful battery life may well increase 50% or more over typical battery life if the battery is used little or not kept fully charged.  This is true for all Optima and other lead acid batteries, not just these sold here on eBay.  Note:  Desulfating seems to help flat plate lead acid batteries more than spiral wound such as these Optimas, while Optimas tend to sulfate at a much slower rate than flat plate batteries. 


My parents in hot, (like 108 F in July), NW Arkansas have been using an Optima Red Top 34/78 from the older lot of these batteries, (Feb-07), since Jun-2010, in their minivan.  Most of their travel is 2 or 3 trips of 2 or 3 miles everyday and several long-distance trips each year.  The battery has performed just fine and was tested Jul-12, using a Midtronics EXP-800, and measured 790 CCA using the AGM tester setting, the battery tested 820 CCA when installed in Jul-10.


Anecdote:  A local customer returned a Red Top 34/78 battery purchased 15 months earlier saying a local battery stored said it had a shorted cell and failed condition.  It had been in a dual battery installation in a larger diesel truck in biweekly service and had tested at 838 CCA by Midtronics EXP800 & 1200 CCA by live load. The measured potential was 3.5 V, and the battery weight had only dropped 0.02 lbs during its 15 months service.  After charging for 120 minutes at 5 A using an Interacter PS series charger, the battery measured less than 9 V, and the battery tested less than 100 CCA using the EXP800 conductance tester.  The battery indeed seemed bad.  The battery was returned to the charger and continued charging for the next 20 hours.  The battery was retested and measured 755 CCA, EXP800;  1200 CCA and 1150 CCA successive live load tests.  Pretty good, and a later conductance test, 775 CCA.  The customer's charger had successively failed to charge the battery, and the battery store failed to correctly assess the battery's condition, apparently because they were not used to a totally discharged battery.  Optima instructions included with the battery show how to charge a deeply discharged battery using a conventional charger but these were not followed.



Questions? 
* Optima batteries are  listed at 760+, 800+, 830+ and 860+ CCA tested ratings.  Aren't these all the same battery? 
   Yes but they tested differently.  All batteries are from one of two lots and are noted by date.  All have the same manufacturer's CCA rating
      of 800 CCA, but some test better than others for whatever reason.  Kind of like the tested horsepower of an engine coming off the assembly
      line;  some just test higher than others yet all have the same parts. 
   Two types of technologies are used to predict and measure performance.
     The Midtronics EXP-800 conductance tester used for rating these is generally very consistent but tends to underrate the CCA rating of these
       Optima batteries, which is good for the Buyer because the actual battery will test better under a live load.  The Midtronics tester is quick
       and convenient and the battery does not require recharging after testing.  It also has a built in printer so results are easily documented for the Buyer.      
     Live load tests are measured using the carbon pile Snap-On MT1590 or Snap-On MT1560, drawing current at one half the CCA rating for 15 seconds at 9.6 V and 70 F.  A live load test is more accurate and realistic than the conductance test but requires a fully charged battery and must be recharged after the test, taking considerably more time than the conductance test.  Live load tests can be compared accurately with other types and makes of batteries whereas conductance testers may or may not be comparable.  The carbon pile testers do not have a printer so results must be handwritten.
* So the 760+ CCA may not supply current as fast as the 860+ CCA battery, but are there any other differences?
  Yes, the batteries testing higher can generally be charged at a higher rate without increasing the temperature of the battery as much.  Under tough,
     high current draw or high temperatures, the higher testing battery may last longer and be more resistant to overcharging.  It may also be able to maintain
     a higher Voltage longer under extended storage.  Also, the higher testing battery will recover faster and have more Amps to deliver under
     repeated high loads.  At low current draw there may be little difference.
* Will the battery be charged and ready for use upon receipt?
   Yes.
