Best battery type for Nagra PL-P

Hello, As Nagra's Service Manager and product specialist for the US, wish to point out something: the PL-P is designed to stay plugged into the PLP-CCC3 power supply at all times during which the batteries will always be charging during use. It was never designed to run exclusively using batteries with external DC detached. (In fact the longest I have heard a PL-P run off batteries is but a few hours, most for less than one hour).

Also, the battery sticks are 4 standard D-Cell batteries, spot welded and heat shrinked, your local Batteries Plus can make two sets for you. Your choice NiMh or NiCd.

Hello Mcintech:
Thanks for answering my letter.

I am interested in buying 2 sets of batteries, I would like to know the product price plus shipping to Spain

As for NiMh or NiCd not which one is best for the PL-P, advise me

? always connected to the network PLP-CCC3 means every day of the year (day and night) or just when running. "

The Nagra PL-P, Serial Number 5500304, was bought in Lyric Hi-Fi New York
I've always had problems with the batteries.

? Periodicity with which to do a discharge of the batteries ".

Please answer soon

If the cells are completely flat, leave the PL-P switched "OFF" over night, with the CCC-3 charger connecter and turned "ON". During this period the trickle charge current, 50-100mA, will bring the batteries to a state where the risk of reverse polarization will not occur.

In NagraNews 17, January 1999 " Periodically, about once a month, it is a good idea to completely discharge the internal batteries, until the PL-P stops automatically. Then return the input selector and connect the charger unit to reinitialize a charge cycle."

If PL-P OFF and CCC-3 disconnected, discharge current is - 2mA . INTERNAL BATTERY WILL BE TOTALLY FLAT AFTER 2-3 MONTHS.

If PL-P OFF and CCC-3 connected but in OFF MODE, discharge current is -10 mA, INTERNAL BATTERY WILL BE TOTALLY FLAT AFTER 15-20 days.

If PL-P ON and charger disconnected or OFF, discharge current is - 2.3 A, internal battery will discharge and the PL-P will automatically stop when 10% of the capacity remains. Approximately 1.5 hours.

If PL-P ON and charger connected and switched ON, internal battery receives trickle charge current, and will remain ON permanently.

Charger CCC3 connected and switched ON : switching the PL-P from ON to OFF begins initialization of the charge routine. 0.4 to 0.6 A for 12 hours. After 12 hours the trickle charge current is supplied ."

Good Morning.  Restarting thread as I am up for replacement of my 8 D cells.  Nagra no longer sells the batteries.  Need to buy them  I hear - BatteryPlus.  Any better place?   I am still unsure about if NiCd or NiMh is the "right answer".  Are both of them same voltage?  It appears capacity is about twice for NiMh.  Since I do not run from batteries, does this have any impact?  Thank you.
