Battery replacement norelco t7500 shaver
If you know how to solder, it's easy to replace the rechargeable
battery in the Norelco T7500 shaver, thanks its beautiful mechanical
design: You just remove the single screw at the bottom, and the entire
charging circuit board & battery simply slides out, still attached to the
shaver by a folded ribbon cable!
Then, you just pop off the plastic shields, unsolder the battery, and solder in a new AA 1.2V NiCd solder-tail battery. Or, you can use a higher-capacity AA NiMH battery for a longer run-time, at the expense of fewer recharge cycles for NiMH.
In either case, dispose of old NiCd batteries properly: They contain cadmium, which is an environmental poison!

Razor charged but not running
You didn't specify how old you model is.
Generally I would say, the battery is failed.
You might try taking it to whereever you bought it and politely ask for a replacement. Its also a good idea not to leave these in cars during sub freezing weather.

I have a norelco cool
You will find a battery pack for model 6711 at shaveroutlet.com. See link below
To open the shaver, you will need to remove the lotion packet cover on the back revealing 4 screws. There may be a screw near the bottom also. Remove screws to take off the back of the shaver and access the insides.
For easier replacement, it is sometimes suggested that you use a modified installation technique. This is to break the tabs off of the old batteries rather than unsoldering them from the circuit board.
This allows the old batteries to be removed but leaves the tabs attached to the circuit board. You can then solder the tabs from the new batteries to the old existing tabs

Norelco shaver doesn't recharge.
If the shaver won't hold a charge it usually means that the batteries need replacement. This requires disassembly and soldering skills. It's not hard to do but if you're not handy with a soldering iron a shaver repair shop can do the work for you. However, if you have to pay to have it done and if the blades are more than two years old and need replacement, you might be better off just buying a new shaver.
