Replacement battery for Norelco 9160XL?

[Sacrider]

Hi, I've got a Norelco 9160 XL that I've been using for about 15 years. The battery is not holding a charge very well. When I look at replacement batteries online, I keep finding links to lithium batteries. It seems to me that a 15 year old shaver is very unlikely to have come with a lithium battery, and I'm concerned that if I install a new lithium battery, it's will be damaged by charging with stock Norelco charger.

What are you all using to replace your battery? If using lithium, do you need a different charger?

Thanks!

According to AI, the 9160XL came with a lithium battery. I am surprised that your original battery lasted as long as it did. You could always open up your shaver and get the part number off the battery.

AI Overview:

The Philips Norelco 9160XL shaver uses a
3.7V Lithium-ion (Li-ion) battery, with common replacements providing 750mAh to 1600mAh capacity. Key part numbers include 036-11290, 4222-036-06410, and 4222-036-11290. These batteries usually require soldering for installation.

Key Details and Options:

• Voltage: 3.7V
• Capacity: Ranges from 750mAh to 1600mAh.
• Dimensions: Typically around 50.00 x 18.50 x 18.20mm or 48mm x 14mm.
• Compatibility: Compatible with 8894XL, 9170XL, 9190XL, 9195XL, and HQ9100 series.

Thanks Phil (and AI)! I'll look into the battery itself to see what the part number is and see if it correlates to the lithium. I agree, it's very surprising the battery has lasted this long.

It could well have a lithium battery, although it wasn’t as common back then. My old Philishave HQ8994 sensotec had a lithium battery but it was the only model in that range that had such a cell, the rest were NiMh batteries as far as I remember. The sensotec boasted a 100 or 120 minute battery life, which was way beyond the capacity of most any shavers at the time, and a unique selling point for me at least. I can’t comment on my sensotecs battery life because it got stolen after I owned it for a year.

Yes, it’s surprising that the battery lasted this long however my ex father in law had the same sensotec shaver as me, he purchased his in 2002 or 2003 when it was released and pretty much used it daily. I recall just before we lost contact the shaver was still working but he complained that it would only hold enough charge for one shave max. So not overly surprising your device has lasted for at least 15 years now.

As others have said I would open up the device and look for markings or a part number on the cell(s) to confirm, then only order the specific type of battery you need.

Be careful also when replacing the battery, I’ve heard a few horror stories about lithium battery replacements especially in shavers so unless you’re confident in that kind of thing I would get a qualified professional to do it for you.

Hope this helps,

I suspect if it wasn't a lithium-ion battery, that might explain its long life. My longest-lasting batteries are NiCd that are also 15 years old, though I don't use the same shaver everyday. I suspect lithiums won't last as long, though I did have a few NiCd in my Brauns in the 1980s that lasted only three years.
