Needs electronics savy, July 9, 2008
This review is from: Shaver Battery Pack fits most Norelco models & others (Health and Beauty)
I would definitely discourage the average person from attempting a battery pack change at all. If you have a mechanical knack, some electronics experience and access to a tiny soldering pencil (3/32" 700 or 800 degree tip), it is doable. On my Norelco 6885XL, my steps were: 1) Let the shaver run to discharge the old battery pack. 2) Remove 2 screws holding the two halves together and take the two halves apart. 3) Use needle-nosed pliers to slightly bend each side of the spring clips inward, then up. 4) After you get the two spring clips off, use electronics side cutters to cut the leads of the bad battery pack about 3/16" above the plastic cradle and remove the bad battery pack. Do not attempt to de-solder the bad battery pack's leads from the printed circuit board. That takes a lot of expertise and special equipment and if you don't know what you're doing, you'll ruin the PC board. 5) Bend the leads of the new battery pack into a `V' shape so that when the new battery pack is in the cradle, the new leads are against the old leads in the PC board. 6) Solder the new leads to the old leads, re-install the spring clips, put the two halves of the shaver back together, and charge the new battery pack.

Replace Without Soldering -- Not Too Difficult, February 20, 2010
This review is from: Shaver Battery Pack fits most Norelco models & others (Health and Beauty)
I agree with others who said do NOT attempt to solder: it's not necessary, and would require the right tools and some decent experience to do successfully.
The no-solder approach described by others worked for me. Here's a slightly edited version of someone else's instructions that took me less than 10 minutes:
1) Let the shaver run to discharge the old battery pack.
2) Remove 2 screws holding shaver case halves together; separate halves.
3) Remove the two spring-clips: using needle-nosed pliers, slightly bend each side of the spring clips inward (or outward, depending on model) to disengage, then lift to remove.
4) One end of the battery pack has two flat metal leads that pass thru the plastic cradle, thru the printed-circuit board and are soldered to the underside of the P-C board. Using small electronics side-cutters, cut these leads as close to the batteries as possible and remove the battery pack. The idea is to leave as much of the metal leads as possible visible and accessible in the cradle.
5) Bend the leads of the new battery pack into a `V' shape so that when the new battery pack is inserted into the cradle, the new leads are forced into contact against the old leads. (Optional: Before inserting the new battery pack completely into the cradle, solder the new leads to the old leads; I did NOT solder them together, the old and new leads make sufficiently tight contact once the battery pack is fully inserted into the cradle.)
6) Re-install the spring clips, screw the two shaver halves back together, charge overnite.
Mine now runs like new!

Norelco replacement battery, January 9, 2007
This review is from: Shaver Battery Pack fits most Norelco models & others (Health and Beauty)
Purchased this replacement battery from Shaver World via Amazon. Delivery was prompt. When I could not figure out how to get the original battery out of the shaver I called the vendor. He went out of his way to give me specific instructions for removing the old and installing the new battery. This involved some non-intuitve techniques and I appreciated the help they provided. Not all internet sellers are willing to be that helpful.
