no--simply because there are live wire connections to the transformer that people will touch and then seek compensation for that carelessness
best if you junk it and simply buy a new charger
This excerpt is from your manual regarding batteries. Considering the extensive battery conditioning designed into this model, I would not think the battery was intended to be a servicable part.:

Model 7526 is not a new shaver. It was made about 8 years ago. If no lights illuminate when the power cord is attached, the circuit board is bad. Unfortunately, Braun no longer makes internal parts for this model
If you like this shaver model and want a similar one, you will find one at shaveroutlet.com. This model uses the same shaving head as the 7526

Managed to fix it - actually was a 7680. Only do this if you:
1. have a small screwdriver set
2. are handy putting little delicate plastic pieces and springs together again
3. are prepared to face the possibility that you might break the shaver entirely
4. you are out of warranty so you don't care if you invalidate it
THE PROBLEM is caused by a small flat metal assembly that acts as a spring to hold the blue button in place. That is held by 4 small glue posts. The glue breaks down, the flat spring falls out of place and the blue button is no long in the right place.
TO OPEN UP THE SHAVER
a. gently remove the plastic cover around the electrical socket underneath, using a small flathead screwdriver to pry it open
b. the two metallic sides of the shaver can be pulled away starting at the bottom of the shaver
c. uncrew the four screws on the underside of the shaver
d. remove cutter block, battery/lcd block (make sure you don't lose the grommet around the lcd display
e. pull the spring and little plastic latch off the underside of the switch, make sure you remember how to put it back (took me almost 20 mins to figure out how to get that back afterwards)
f. slide the switch all the way up and pull it off the slide - you might need a little gentle force and a flathead screwdriver to coax it off - be careful you don't break anything here
g. remove the trimmer from the rest of the switch
h. put the blue piece back in place (mine had fallen out), then glue the flat metal spring back in place. I smeared brush-on crazy glue on the flat surfaces to hold it in place, I would imagine a four drops of reasonably strong glue on each of the glue posts would work best. Wait for the glue to dry and achieve strength.
i. slide the trimmer back into place, then the plastic latch and spring - this is the tricky part. Make sure the switch can slide on/off in all positions properly.
j. put the display/battery & cutter block back in place. put the back of the shaver on, hold the shaver together with your fingers and test the switch works in all positions without jamming. If so put the four screws back, followed by the metallic sides followed by the plastic cover of the electrical socket.
This is a common problem with the clean/charge base for model 7526. The mechanism inside is broken. You can replace the upper housing that includes the locking arm or you can replace the whole system. Both options are available at shaveroutlet.com. See links below
The procedure outlined in the video will be similar to the one required for disassembling your model 7526 shaver. Here is a link to the user's manual for that model in case you do not have it already:

The stands for these Syncro models are notorious for breaking. If your shaver charges direcly fom the cord but not the base, it sounds like there is an electrical problem with the base...probably the circuit board is bad. Parts that you would need to fix it are no longer availale from Braun. You will need to replace the unit. You will find a replacement at shaveroutlet.com. See link below
If the unit still works but just doesn't hold a charge well, you can just change the batteries. It is much less expensive to do this. You will find compatible batteries at shaveroutlet.com. You will need two. See link below. Scroll down the page for helpful video instructionshttp://shaveroutlet.com/shaver-replacement-parts/shaver-replacement-battery-aa-nimh-p-108.htmlThe PC board for your model has been discontinued by the manufacturer. You may be able to find a store on-line that still has some old stock on hand if you prefer to change the whole board
This is a common problem for older cleaning bases. The part is worn out. You will need to replace the upper housing of the cleaning base. You will find this item available at shaveroutlet.com. See link below
