I have a device, never really used, which now seems not to work. I've split it's case apart and checked it out, and reckon the battery has gone duff while it lay in it's box on the shelf.
I'm willing to try to replace the battery but a search brought up very little from the Internet. I suspect it's no longer made; in which case I'd need an equivalent small enough to fit in the same space.
It's a "AE451834P" Thomson lithium ion rechargeable battery, 3.7v.
I don't suppose someone here knows about batteries and what today's equivalent would be; is there ?
Many of these batteries are effectively AA cells stuck together - 3 cells would be 3.6V and should work OK. If you have any AA cells knocking around try measuring 3 stuck together and, if the size looks like it will fit your device, give it a go.
If this the right battery

it is rated at 230mA/H, so depending on the dimensions there should be an equivalent, or higher rated, one available from Amazon (or elsewhere)
Thanks all, I assumed there must be an equivalent but was hoping someone may have a table or something that indicated the right choice. Problem is that space is tight so it doesn't have to just be electrically equivalent but, to the best of my ability with a tape measure, 28mm × 17mm × 4mm. That's a lot of surfing & checking without a steer in the right direction.
Oh I look in occasionally Khan, but broke the compulsion. Trouble is it was just replaced with another for a pointless but addictive game started to pass time during the Covid panic period.
