They are advertising Sanyo battery at the higher price, but sent me generic one, that generic-knockoffs probably made in China. Look for the Sanyo on eBay. They are cheaper there and hold the charges in your shaver much better. And they are 700mAH instead of 600mAH. Amazon should be looking into such practice, when seller advertised products with pictures of brand but sells generic instead.

The battery definitely seems to hold a charge longer than the original did. Some soldering skills are needed to replace the battery but it's only the two connections on the battery itself. I'm very glad that I replaced the battery instead of buying a whole new trimmer.
Wonderful little addition to my old beard trimmer. My old battery was done and would not hold a charge at all, i used a simple soldering iron and unsoldered the old battery from its tabs and re-soldered the new battery into its place, a good charge later and i can notice my trimmer has more power and holds a charge wonderfully. Excellent product
This is a general comment about some Braun shaver batteries, I am NOT reviewing this particular battery. I gave it 5 stars to not taint it with anything lower since I don't know this exact battery.
Obviously the trick it to figure out which battery you need and that is not easy, both voltage and physical size, and maybe mAh are important. Then you need special soldering tools and some experience to replace it without damaging the PC board. I think you need a battery with tabs or leads already soldered onto the new battery, although some people have had luck unsoldering the old battery and leaving the old leads soldered onto the PC board. That has the advantage that it could avoid overheating the PC board which could occur by unsoldering the old leads (and new battery leads) at the PC board itself. However in my case the new battery sucked too much heat away and also would not tin properly, so I recommend you find a battery with leads then unsolder the old battery from the PC board itself on both ends. Do not unsolder the leads from either the old or new battery, just get the PC board holes free from solder and insert the new battery. This requires a "solder sucker" to remove the solder quickly after it is molten.
To find a battery at a battery online store, try searching for "AA solder" or leads or shaver battery or...
I just replaced the single 1.2v AA size NiMh battery in my Braun 5414 (same as 5415) and it works fine now. It was tricky to remove the many small screws especially at the top to disassemble the case.
For the Braun 5414 I bought this 1.2v NiMh 1300 mAh battery for [...] + shipping. It is described as razor-17 Dantona:

But I don't know why this AA size 2000 mAh from Thomas Distributing wouldn't work as well for only [...]. It doesn't show voltage and size but says it is "AA" so it must be 1.2v and the same physical size. Thomas is famous for selling Maha battery chargers and many batteries also:

Now I don't know if using a 2000 mAh instead of a 1300 mAh would be a problem. It seems to me that as long as both are 1.2v (in my case) that they would both be fine. The larger mAh would take longer to charge but hold the charge longer it would seem. I don't see why it would provide too much current and damage anything. Perhaps others have opinions?
Also here are some resources with a set of Braun shavers numbers that go to 1 of only 3 battery sets:

One more thing, not related to shaver batteries... Sanyo batteries are probably made in Japan!!! At least their famous Eneloop batteries I just bought are, which are a great option for AA NiMH batteries in general (digital cameras etc) as they are a new technology that do not have the self-discharge problem. They would be especially good for use in gadgets you don't use a lot and don't recharge a lot which is an issue with NiMh in general. In my case it is my Wii game controllers. Sanyo claims that most NiMh batteries will discharge to 0% after 1 year compared to 85% charge remaining on the eneloop batteries. The downside is this technology is presently limited to lower mAh, currently 2000 mAh and not the 2650 mAh of other brands using the regular technology. But then again the Eneloop type doesn't lose their charge like the regular ones so you may not have a fully charged battery like you think you do and it won't provide the full 2650 mAh over time. Also get the Sanyo charger or any other one that is a slow charge (like 200 ma) and not a "quick 1 hour charger" (too much current will damage battery) or worse yet a cheap charger that is simply timed and not a smart microprocessor charger. - Replacement Battery - Norelco - Norelco Razor Battery'
