Polarion PH-40 battery disassembly?

[Patriot]

My parallel opening set would probably do the trick - but then I'm not exactly close. Patriot, I'm a little disappointed that you don't have every conceivable tool you might ever need already in your toolbox...

Could you swing by really quick with that parallel set Bob, that would be swell!! What, you've got a problem with driving 500 miles now..:nana:

Hey, the large snap ring pliers opened up the shell. They appear to be the same sanyo cells as in Lips pictures. Now I we just need to find cells with tabs but I'm a complete noob at this. I guess I'll need some shrink wrap as well.

It was a long time ago but when I was buying my Panasonic NCR18650s off Ebay, there were two sellers. One with tabs and one without. Oh, and Patriot, I'm already enroute. Wait up for me, ok?

Just took a look on Ebay. A "panasonic ncr" hit took me to a seller whos pic looks to show cells that at one time had tabs that were welded on and have been removed. There are 4 small spots on the electrode. Maybe communicate with the seller to see if he has them with tabs?

Proper tool or careful opening will probably keep locking tabs intact. I used couple pieces of electrical tape on slit to keep them closed...


Ultrafire has some 3200mah protected batteries out there but they probably overrate the mah. Cut the skin to get to the unprotected? Sanyo tabbed cells are on ebay too...


My understanding is Lux rebuilt the Polarions by making his own shrink wrapped pack and adapting that to the protection circuit.
There may be a simple way to have some shrunk wrapped packs built with high capacity cells and then for the end user to simple snip a couple-three wires, re-solder and redo the pack. Not sure though!

We want PICS!!!

Hmm... I suppose I'll need some snap ring pliers... wonder if anyone around here has some...

I'll need some shrink wrap as well

Me too... I don't suppose Mrs. DM51's clingfilm would do, lol.

Or any tool that will work as a spreader. Once you apply a spreading force at the end of the battery, it's easier to get a flat blade screwdriver between the halves and pop the clips open. Haha! Yeah, Cling wrap might just work!

I probably won't dig into this project until after vacation. I've just got too many different things projects going on and a vacation coming up, to jump into another right now. I might decide to pass altogether and just ask Lux to do it if he'd be willing. I'll have to decide when the time comes. The pictures that Lips posted are excellent though! I started to thing, 'hey that doesn't look too bad' and then saw that razor light pack!

Hi Guys,
I am looking for an agent/distributor of Polarion products in Hong Kong. Do you know any contact number I should call? I need a large quantity of PH40 for a project.

Thanks a lot!

Hi sassymouse,

Welcome to CPF! The best person to contact is Ken J. Good from Polarion USA:

[tab665]

Re-animation !!

Hello to old thread.

Just had to take my pack apart as it died
This thread helped a lot - Thanks All.

My pack is slightly different - 5 Tabs per side and some mastic type rubber glue - Thankfully not too much glue effect so it came apart OK.



One of the pairs in my pack is showing a reversed polarity (only small) so that level needs replacing at a minimum - will probably just update with 8x 2600mAH cells as they cost only a little over double the cost of 2x 2200 cells.

My pack only has one PCB at the charger end and a roundish contact end PCB.

Thanks for the assist,
Pete

Good info here. I will be swapping out with 8 x Sanyo NCR18650GA 3500mAh soon. A local battery shop is willing to tack the contacts to the cell ends for me.

Update 2020 - Polarion still makes replacement batteries. We do not advocate taking batteries apart. New batteries are 5700 mAh and contain the new charging board that eliminates deep discharge problems that occurred in 2011, 2012.
