PP3 9V USB RECHARGEABLE BATTERIES

#1

Banggood (China) have PP3 9v/400 and 800 milliamp RECCHARGEABLE LITHIUM batteries available ,that can be charged by a special mini USB cable (available from Bangood) from your lappy or PC.

Bit dearer than the usual rechargeable types. AlieExpress have them cheaper I noticed…not much cheaper. USB cables available to charge 1, 2 3 or 4 batteries the same time from the one source. Batteries indicate when charged and are fitted with the safety PCB. Connections by the usual PP3 type.

AlieExpress do not appear to have the charging cables.

How about a link? banggood search gives 0 results for pp3 rechargeable lithium, and 9v rechargeable lithium.

Clearly a special cable, since USB is 5 volts (http://www.largescalecentral.com/externals/tinymce/plugins/emoticons/img/smiley-cool.gif)

You have a choice of the number of leads as regards number of batteries to charge from same supply…

Thanks for the info Ross, I’ve been thinking about these. Only problem, signed up to the site and all those batteries are out of stock and some with no re-stock date. Tried AlieExpress but can’t get anything but the home page to load. Not a criticism just what I’m seeing right now.

Their offer of 2 batteries is out of stock…Singles still available and there are two makes to choose from. However…I wanted a couple and had to buy them from AlieExpress at a priced pair AND they were slightly cheaper…(http://largescalecentral.com/externals/tinymce/plugins/emoticons/img/smiley-tongue-out.gif)

TRY THIS…

NOTE…AlieExpress now appear to have charging USB cables look under batteries and chargers…

Interesting, found a video of what is inside, two 3.7v cells, with a DC-DC converter to boost to close to 9v, although some people have measured these at 8.13 volts.

#7

The ZNTER type I received from Bangood measured 9.16v on the digital…

#8

The voltages seem to be all over the place…
