Spice AAA battery adapter

[isanchez]

Hi,

A few weeks ago I was telling my friend José González how difficult it was for me to use "spice" models in a usual situation. Many of the "spice" calculators I have have one or both contacts ruined and the charging contacts are unusable. This is mainly due to two reasons: the first and most frequent is to leave the batteries inside and let the acid act, this is aggravated when the batteries increase in volume and burst the back cover; The second is that AA-type batteries are used, which currently seem to be a little longer than the original ones, creating internal stresses that break the back casing. These circumstances make me have taken some hatred for them.


Today I received at home an adapter designed by José that has left me speechless. It is an adapter to use two AAA type batteries (rechargeable or not), so that they fit perfectly, without introducing any tension on the casing and facilitating their charging or replacement outside the calculator.

It seems to me a great work that I want to share. I attach some photos.

Greetings

Ignacio
