1. A battery cell controlled automatic battery charging system which allows faster charging while simultaneously restricting overcharging to reduce cell damage, comprising:
- a. a battery charging means operable to charge a bank of batteries;
b. a plurality of battery cell probes equal in number to the number of cells in the bank of batteries, one cell probe being provided for each battery cell, respectively;
c. a display means including electrical circuitry connected to said battery charging means;
d. each said battery cell probe being connected to said display means; and
, each said battery cell probe being operable to sense and monitor the condition of its respective battery cell and indicate by electrical signals to said display means whenever a cell is out of specification by being any of low in charge, overheated, and low in electrolyte;
e. a cell alarm means provided on each said battery cell probe to indicate to an operator each of said battery cells that is out of specification;
f. said display means and electrical circuitry being operable to visually display the condition of the most out of specification battery cell in the bank of batteries and also to provide a control signal to said battery charging means to cause said battery charging means to charge said bank of batteries whenever one of said probes indicates that a cell has a low charge;
said display means and electrical circuitry operable to cause said battery charging means to stop charging whenever a battery cell becomes overheated or low in electrolyte, whereby faster charging is allowed with reduced possibility of over charging and cell damage.

Abstract
A battery cell controlled charging system, consisting of a display unit, battery cell probes, a battery charger and circuitry for controlling the charger, monitors the specific gravity, electrolyte level and temperature control of each cell in a multi-cell lead-acid battery and uses the information to automatically charge the battery when a cell or cells become out of specification while restricting overcharging which is damaging to cells.
