Hello time-nuts,
I have 5061A and 5061B units with the battery option and dead battery
packs. My question is what makes the most sense when refurbing these units?
-
Yank the old battery out and just leave it that way. Running the unit
on a UPS would preserve the functionality.
-
Replace the pack with a rebuilt NiCd pack. I'm sure Batteries Plus
would be happy to do it, but sounds expensive.
-
Replace the pack with a NiMH pack, and really crank down the float
current of the 5061.
-
Replace the pack with Li-ion battery. Would be a much smaller battery,
but the charging circuit would have to be pitched. Building in a Li-ion
charge controller sounds like it could be a project (which I don't
necessarily want).
-
Yank the old battery pack and run the 5061 on two 12V batteries with an
appropriate power supply/charger (basically a version of #1).
Any thoughts on these or other options would be appreciated. Thanks in
advance.
Regards,
Skip Withrow

it is a "ventilated flooded" battery?

if it s a flooded battery it is very easy to fix it

I don't know which option would be best, but rebuilding the pack may not be
expensive. A rebuilt NiCad pack for a Flukemeter only cost me $12. Fluke
charges $120 for a new one.

Unless you are in a very unusual location, put it on a UPS.

Skip,
I've rebuilt the NiCd battery packs with tabbed half D NiCd cells that are about $5 each (with tabs, shipped) and it takes 20 of them and some time to disassemble the pack and solder the new cells together. They will eventually die and you will have to replace them again. The half D NiMH cells I've seen have a larger capacity and noticeable more expensive.
I think I would choose to use an external 24 V battery with an attached battery charger as the backup rather than a UPS. Batteries would be cheaper than NiCd's but more 'clumsy' to move and keep the unit powered.
The HP 5085A and HP 5089A were designed to take two 12 V SLA batteries and supply the needed charging circuitry and connectors to connect to the unit as a backup. It could be mounted in a common cabinet with the 5061A or B as a 'movable' (not really 'portable') unit. I have a 5085A that serves as backup to two 5061A's each with Opt 001 clocks. The 5085A and 5089A don't show up often on theBay and their original batteries I have not been able to find. I have made some minor modifications and was able to fit two Panasonic LC-X1228AP batteries in the unit.
https://na.industrial.panasonic.com/sites/default/pidsa/files/panasonic_vrla_lc-x1228p_lc-x1228ap.pdf
Choices 3 and 4 seem like a lot of work, particularly the Li Ion option.
I like the idea of the built in NiCd pack in that you can easily (well, it's heavy) move the unit and keep it powered.
Good luck.
Joe

Hi,
These days, NiCd cost us a lot here in Europe as Cadmium is something
they want out of the market. Kind of not so nice for health. Still
available thought. I avoided loading NiCd into stuff from pure cost.
PHK would vote for lead-batteries. I use LIPO(Fe) for portable stuff.
Cheers,
Magnus

I went with option #2 and opted for batteries plus to rebuild the packs as I recall it was about 80 dollars to rebuild the pack which included a 1 year warranty
The problem with moving to lithium batteries is building the battery management system and safety systems needed for the SAFE operation of lithium cells.

Much has been said and I favor the lead acid approach.
My luck with nicad has not been good. I purchased brand new ones for a Tek
TDR 1502 and they did not last that long and as mentioned quite expensive.
I actually have some older nicads that must be 30 years old and they still
hold a charge, have not leaked and are pretty amazing. I believe that like
all things business has figured out how to give them a defined lifetime.
(Short)
The lead acid battery approach offers simplicity.
Wide range of charging approaches that are simple.
Can choose to use a plain old UPS as an example though the efficiency is
not great.
Good luck Skip.

Hello time-nuts,
I have 5061A and 5061B units with the battery option and dead battery
packs. My question is what makes the most sense when refurbing these
units?
-
Yank the old battery out and just leave it that way. Running the unit
on a UPS would preserve the functionality.
-
Replace the pack with a rebuilt NiCd pack. I'm sure Batteries Plus
would be happy to do it, but sounds expensive.
-
Replace the pack with a NiMH pack, and really crank down the float
current of the 5061.
-
Replace the pack with Li-ion battery. Would be a much smaller battery,
but the charging circuit would have to be pitched. Building in a Li-ion
charge controller sounds like it could be a project (which I don't
necessarily want).
-
Yank the old battery pack and run the 5061 on two 12V batteries with an
appropriate power supply/charger (basically a version of #1).
Any thoughts on these or other options would be appreciated. Thanks in
advance.
