SPECIFICATIONS LOW MAINTENANCE BATTERIES
TRUCK SERVICE MANUAL TM 5-4210-230-14&P-1 3. Boost  charge  12-volt  batteries  at  15  amps  (6-volt  and 12-volt   heavy   duty   batteries   at   30   amps)   until   the specific gravity of the electrolyte is 1.250 or higher and electrolyte temperature is at least 15.5°C (60°F). BOTH CONDITIONS  MUST  BE  MET.    If  electrolyte  bubbles violently   while   charging,   reduce   charging   rate   until excessive    bubbling    action    subsides,    then    continue charging until 1.250 specific gravity and 15.5°C (60°F) are reached. If  the  ambient  temperature  is  0°C  (32°F)  or  less,  it  is imperative that the above instructions be followed. 4. Check  volume  of  electrolyte  in  all  cells  and  adjust  to prescribed level with additional electrolyte as required. 5. Install battery in vehicle as instructed under REMOVAL AND INSTALLATION.  Be sure of proper polarity. Dry    charged    batteries    may    be    placed    in    service immediately  after  activation.    However,  to  insure  good performance these additional steps are recommended. Check   the   specific   gravity   of   all   cells.      Under   good storage  conditions,  the  electrolyte  specific  gravity  on activating a dry-charged battery will drop approximately .010 and temperature will rise 4°  to 5.6°C (7°  to 10°F) within  twenty  minutes  of  filling  the  battery.  A  battery under  these  conditions  requires  little  boost  charging. However, should the specific gravity drop .030 or more with    a    corresponding    increase    in    temperature,    the negative   plates   have   been   oxidized   and   the   battery should be fully recharged before use.  Also, the battery should  be  recharged  if  one  or  more  cells  gas  violently after   the   addition   of   electrolyte.      After   electrolyte   is added,  check  the  open  circuit  terminal  voltage  of  the battery.    If  a  12-volt  battery  reads  less  than  10  volts (less  then  5  volts  on  a  6-volt  battery)  this  indicates  a reverse cell or an "open" circuit and the battery should be replaced. After   the   dry   charged   battery   has   been   activated,   it must  be  serviced,  handled  and  kept  charged  like  any other wet battery. After battery has been in service, add only approved water.  DO NOT ADD ACID. CTS-2771  Page 18 PRINTED IN UNITED STATES OF AMERICA
