How would you make a 12v battery?

Best Answer

A galvanic reaction between two dissimilar metal in an electrolytic solution will create a small voltage potential. By coupling these in series you could make a battery of "cells" of 12v. A simple search should get you a galvanic series list. As for the cell and electrolyte try an ice cube tray and lemon juice.

Can you plug in pest control into a 12V battery?

In order to use the "plug in" pest control with a 12V battery, the device would have to have power requirements less than or equal to that which a 12V battery can provide. The pest control would also need an adapter to use the 12V battery.

Can you charge batteries in series with 2 separate chargers in parallel?

Not in parallel NO - unless each charger is twice the voltage required for a single battery. For example if you had 2 x 12V batteries and placed the in series, you would have a 24V battery. If you had two 12v chargers and put then in PARALLEL with each other, you would then have a 12v charger with double the current handling. Of course if the chargers were 24v ones, then it would work fine. if you have 2 x 12v batteries (for example) and wished to charge them with separate chargers (actually quite a good idea), then each charger would be over each battery. So the batteries would be in series, the chargers would also effectively be in series too. Basically another way of looking at it would be two have a 12v battery with a 12v charger to your left and then on the right another 12v battery with a 12v charger on it. Yes you can connect the two together in series. The only slight caveat is that the chargers must be isolated from each other - and not for example a "dual output charger" which simply has an extra pair of leads but a shared charging system. - 12v + - 12v + ---------+-BATTERY---+----------+--BATTERY--+-------- - | |+ - | | + |=CHARGER=| |=CHARGER=| - <------------------------------- 24 v ----------------------------> +

Will gerbing's 12v hybrid battery work with the 12v corded heated glove liner?

Yes, their 12v mobile battery pack will work with all of their 12v gloves that are otherwise designed to be connected to the motorcycle's battery. The only downside to connecting the glove liners to the mobile 12v battery is that there is no place to store the battery on the glove itself, while all of the Core7 and the Hybrid gloves all have battery pouches in the cuffs.
