What kind of batteries can be used in medical treatment? Is there any domestic factory specializing in the production of medical batteries?

Your question is a bit general, with what I know, large medical equipment is generally used on the backup power supply, are large lithium battery packs, if it is a personal use of home medical products, generally used to nickel-metal hydride rechargeable batteries, and with the development of lithium-polymer batteries as a lighter power supply in order to gradually become the mainstream of the market.

Specializing in the production of medical battery manufacturers almost no, there is not likely to be a large factory, but I know that there is the production of lithium batteries and nickel-metal hydride batteries in the supply of related products, with my knowledge of the largest domestic manufacturers of sphygmomanometers and medical supplies for the battery supplier is the Ger's ace battery factory. Because the volume of medical supplies is not very large, these big factories should have other products to supply other areas, such as electric bicycle batteries, modeling batteries, household appliances batteries, and so on.
