Additional batteries and external battery chargers

[bcnaz]

The battery used will be identical to the Samsung J7 3000mAh battery.

A quick search shows quite a variable size of the battery for "the" Samsung J7, depending on
year and full device name. And given suffices like neo, duos, etc, I may have missed a few more sizes.

The BJ700 and BJ710 are the common ones, so the BJ700* for the 2015 J7 might fit.

85.88   x 39.50 x 4.30 mm        3000mAh      J7 Neo 2017   EB-BJ731ABE / ...

(names and interestingly "exact" sizes as mentioned in ebay listings, unverified; and I've no idea about user-visible diffs between e.g. BBC, BBE).

Luke, can you give exact device name or battery part name?

thx

 When I contacted a vendor asking about the size of his ' J7 '  battery,

*  His reply was that there is more to be concerned with than just size.

Apparently there are chips in the batteries with firmware that must agree with your particular phone...?

He 'suggested' using batteries that were approved by your particular manufacturer...  errr  ? ?

UNLIKE my truck,  I just get the biggest/ highest rated that will physically fit in it.

I guess the circuitry in a cell phone is more particular  ?

**  Is there a particular model of phone we can compare the Pine phone to,  to 'match-up' the battery  ?

THANKS
