With all this recent 5065A talk I decided to pull mine out of storage and fire it up. After a little time to let everything warm up and settle in, I'm happy to report that it's working just fine!

My 5065A has the battery backup option, and the battery is the original one (1420-0066, Energy Sales p/n ES710, 25.2V 1.4 Ah). Not surprisingly, the battery is quite dead. Does anyone any insight about installing a more modern battery (SLA or NiMH, perhaps) that will fit in the battery compartment in the 5065A?

I've looked at a few small 12V/2.2Ah SLA batteries that are physically small enough that I should be able to fit a couple in the enclosure and connect them in series to get 24 volts out, but I want to wait until either I have assurance from someone with more experience than I that this will actually work, or a better idea about a more suitable replacement.

Thanks,
Stan

Hi

One very practical option: Pull the battery and don’t replace it. When the unit
next comes out of storage, run it on a very normal UPS. The battery was
a fine idea back in the era when this gear was newly designed. These days,
the better option is an external “bulk” backup.

If you are going to run 24/7/365, the charger circuit in all of these gizmos (HP
liked battery backup …..) is not the best for long term battery survival. It’s not
awful, but it’s not what you would do today. If the unit goes into storage most of
the time, batteries really don’t like that very much either.

I don't know what your package requirement is, but I would at least LOOK at LiFePO as a solution. These guys provide all my radio related batteries...

The smallest 24vdc I see is 10 Ahr, but they are very responsive and will either help you out or send you in the right direction.

On 5065A backup batteries, The Batteries Plus does a good job of rebuilding HP/Agilent battery packs.

I paid 125 a couple years ago to have my 5065A pack rebuilt.
