Norelco series 2000 battery replacement

Hi all,

My 2 year old series 2000 shaver is nearing the end of its battery life and I’m considering replacing the battery myself. I’ve watched numerous YouTube videos on people doing this with other Philips models and it looks fairly straightforward. I have good soldering ability and a decent electrical knowledge so thought I might as well. If I screw it up I have a Philips series 1000 on standby.

My question is, can I fit a generic 1.5V NiMh AA cell, or is there a specific battery that I should be using? From reading the specs on the shaver these seem to be the only requirements, other than being around 49mm x 14mm in size?
 
According to Philips, your shaver uses a Lithium-Ion battery:

Don't put a NiMH cell in there. The cell would be destroyed in very short order by the Li-Ion charging circuitry, probably ruining your shaver if the cell vents due to an overcharge and loses electrolyte.

It's a bummer that your shaver's battery is failing after just a couple of years' use. I'd expect longer service life out of a Li-Ion cell. Unfortunately, unlike NiCd cells, there isn't anything you can do to try to revive a Li-Ion cell.

Thanks for your response.

I’m pretty sure my series 2000 is of the new variety, and almost 100% certain it takes NiMh batteries.

This is the one I have:

Does that change anything?
 
There should be some kind of notation on the existing cell denoting whether it's Li-Ion, NiMH, or NiCd, and also indicating the cell's capacity in mAh.

If it's indeed an NiMH cell, you've got tons of options for a solder-tab AA NiMH cell. I've had good luck with Tenergy cells.

I’ve just found the instruction manual and it says for sure it’s an NiMh cell. So providing I can match the specs ie 1.5v and the correct capacity I should be ok?

Yes, you should be good to go. It's tempting to put a higher-capacity cell in there, but try to match the capacity of the original. The cell is probably 1.2V.

Thanks for your helpful advice, I’ll probably take the shaver apart tomorrow to establish the correct capacity. I’m almost 100% sure the voltage is 1.2v so once the capacity is confirmed I can order the right battery 👍
