Batteries run down too quickly in my unit. Sometimes they run for 3 hours or more and sometimes for slightly over an hour. What is wrong with my unit?

Here is a memo we sent to our dealers and service people about batteries. Please realize it is therefore a little blunter than our usual FAQ's:

If you are using alkaline batteries, we recommend the use of Eveready alkaline batteries particularly in our synthesized (frequency agile) equipment. Other brand batteries may work perfectly well, but Eveready is our standard for testing and analysis. In different purchases of Duracell batteries from different locations, we have found the battery life to vary by more than 2 to 1. On the other hand, we have found very consistent results from Eveready batteries. Also, in all tests we have done, a standard Eveready Energizer always gives us longer battery life than standard Duracell Procells. If customers call complaining of battery life we should ask them to try an Eveready Energizer before returning equipment for repair. Assure our customer that this does not mean Duracell is a bad battery , but that the Duracell battery was not intended or designed for the heavy current draw our equipment requires.

Always try to get the customer to try the Eveready batteries. If it is necessary to convince the customer to try Eveready's in a test, we can send them free batteries. That is cheaper than us wasting our time and theirs testing a perfectly good unit and finding no problem. Try to talk to the actual user of the Lectro product rather than someone who has been tasked with returning the unit and has no idea of what is going on. Remember these points.

  1. Cold alkaline batteries have short lives. To get full battery run times, the batteries must be at room temperature or higher.
  2. Standard Duracell batteries have 90% of the life of standard Eveready batteries in our equipment.
  3. Some Duracell batteries that we purchased at retail were inconsistent in our equipment and occasionally "failed" after as little as 1.5 hours of operation. They may have been counterfeits.
  4. The worst offenders for battery life are the UCR201, UM400, UH400, UM250, UM450, and UT700.
  5. Using 48 Volt phantom power on the UH plug-ons, will drain the battery even faster.
  6. Our battery life numbers are based on complete discharge of the battery, i.e., the unit is run until the battery is completely discharged and the unit shuts down. If the customer discards the battery at the first indication of falling battery voltage, then they will only get about one half of our specified battery life numbers. The customer needs to read the manual to understand what the battery indicators are really telling him. There is probably no diplomatic way to tell a customer that simple fact.
  7. It is very rare that a unit is drawing too much current or has maladjusted battery status indicators. Ninety nine percent of the time, we find that there is nothing wrong with the Lectro unit. I repeat, 99% of the time, it ain't us.
  8. In general, our transmitters pull more power from the battery than other brands and thus require more care in choosing and using batteries.
  9. There are a number of FAQs on our web site about batteries and tests we have done.
  10. Lithium disposable 9 Volt batteries have problems with our high current draw and if they are not stored before use in an airtight pouch they will fail very quickly.
  11. Rechargeable Li Ion batteries such as iPower are much more economical and give slightly longer performance than standard alkaline batteries. Customers have seen iPower batteries shut down at turn on in the UH400 due to sensitive protection circuity in the iPower battery.
