I won this on ebay for my LX body!
Inside my LX NiCd Battery pack there are 12 dead batteries 1.2V 1/3AF size 16x16.5 mm
It look like Sanyo N-225ae. Same size have GP45AFH.
Did anybody know, where can I buy IT?

Please, don't let die Pentax fan!

I have gone through this, and bought a set of NiMH and replaced them myself. There was a site on the net that walked you throught how to replace them. Also I would recommend batteries plus, because the problem I had is I didn't have a way to weld the batteries to each other. I soldered them, but not the same. My pack did end up working fine. I will see if I can find the web page for you, it said which batteries to buy and show pics of everything. Also I never changed the charger, just charge it for longer and after 3 years it still works fine.

An example of a source of "1/3AF" size http://www.batteryout.com/products/4428383 ; 1/3AF-210WT $2.18 at Battery Giant

I can not find the link where the guy rebuilt his with the nimh. I might have a print out but he explained his logic and had pics. Like I said I have no way to weld e packs together with out heat which can ruin the batteries. Batteries plus had a way to weld them together and they don't charge for the labor only the cells. They did a great job and even shrink wrapped them into the separate cells like the factory did.

I have a technology to combine new batteries into battery pack - this is not a trouble.

The guy you are thinking of is Rob Studdert. The link from his site (Digital Image Studio, Photography) to the battery pack rebuild no longer works but you could try emailing him - distudio@gmail.com - and see if he still has the files somewhere. I have a copy of the information but would not pass it on without Rob's permission. I think Rob is still active on the PDML.

That's the second reference to PDML I've read today!! There must be some kind of harmonic convergence happening here.

That is correct. I found my print outs... In the future I just want another battery grip m to get away from having to rebuild my stuff again. But I did use the nimh he recommended and it did work.

Hi Paul et al,

My old site is a bit stale but I just put the LX BP page back up:

Digital Image Studio, Pentax Ni-Cd Battery Pack LX refurbishment

Cheers,

Rob

Thank you Rob for that info I greatly appreciate it.

All around the World said me: It is unreal to find new. The best case you can find batteries, manufactured 2004.....
So, I find a radical solution of my trouble: two 8.4 V battery CR-9V size. To correct voltage I use a STI L7815CV voltage regulator.

But the first version of modification have one feature - it can be used only 48 hours after charged

I connect voltage regulator before the power on-off switch. That is wrong because my charge leaks out through voltage regulator.
In the new version voltage regulator will work only when my LX NiCd Battery Pack switched on.

I know this thread is old but I thought I would refresh it anyway since it has been a while. I changed my LX battery pack NiCd to Nickel-Metal-Hydride per Rob Studdert's instructions earlier in this thread and the procedure is still valid. The nice thing is that the cell voltages for NiCd and NiMH are the same so that the charger still works with the new chemistry. Found cells by googling "3X1/3AA NiMH battery pack with tabs". Mine came from a company called batteriesinaflash.com although I am sure there are other sources as well, At the end Iof the day had a working mortor drive again.

I saw some Exell AA sized 3.6v 300mah NiMH tabbed on eBay. https://www.ebay.com/itm/273651844205

$36 for 4 and free shipping. They would work with LX battery pack but not with M...as the M has 2 2/3 AA and 2 4/3 AA. But I think those sizes are available too.
