LiPo vs Rechargeable Lithium 123

Nick Odell · 2021-04-17T12:31:10+00:00

The LiPo battery in a tiny remote controlled helicopter toy hasfailed. I can tell it's failed because it has blown itself up like aparty balloon! I was surprised at how low the capacity was - 200mAhwas printed on the side. I've now replaced it with a similar 350mAhLiPo battery.I was just wondering how the performance of these LiPos compare with amore conventional rechargeable lithium 123 cell. The 123 only weighs4g more than the LiPo yet seem to have many times the storage capacityso presumably there must be some reason why they aren't used in thisapplication. Any thoughts?Nick

Marketing?

I have lots of pound shop NiMh AA rechargeable batteries - I know, they are completely different but when some similar cells are available at 2100mAh, the ones made for pound shops are invariably

350/750/800mAh

The full text from one I have here (different brand) reads "The voltage of full charge and cut-off discharge is 4.2 and 2.75v"

I use these cells in analogue cameras. I've never kept them going until the low battery light comes on in order to find out how long they really last because I tend to put freshly charged cells in before I go out. However, using auto-focus, auto-zoom and motor film transport, on-board flash and all the other gubbins, I can run through two or three films and the mechanical action is still as crisp and sharp as it was in the beginning.

When a phone has a replacement battery capacity far in excess of that supplied with the phone you can be sure the higher capacity is a work of fiction.

It's much the same with any other battery in that if the capacity is far in excess of that from reputable battery manufacturers then the no-name manufacturers are lying.

I forget which manufacturer t was, but one firm said the reason that their phones weer catching fire was because people were fitting non OEM batteries.
