TM 9-6140-200-14
(4) The battery cell contains 60 to 75 percent Pb and Pb02 by weight. The
battery cell contains an acidic electrolyte solution of between 28.3% and
50.5% H204 by weight.
(5) Pb and Pb salts are toxic and hazardous materials. It is recommended to
turn-in LA batteries wet. If you must drain the battery, test H2S04
electrolyte for Pb prior to disposal. If Pb is below the RCRA regulatory
limit (5.) Mg/L, then the electrolyte may be disposed in accordance with TG
No. 126 with the concurrence of the IEO and the affected waste water
treatment authority.
b. Solid Waste Characterization.
(1) Under federal RCRA: HW with a Environmental Protection Agency (EPA)
HW number (EPA HW#) of DOO8 for Pb.
(2) Bioassay findings: Not tested. Or summed to be toxic based on Pb
content.
c. Handling (see Para 5.5).
WARNING
Do not use metal or galvanized equipment when draining
electrolyte from Lead-Acid batteries.
Do not use finely divided combustible materials (e.g., sawdust)
to absorb an H2S04 is highly reactive and can react with finely
divided combustible material on contact.
Do not attempt to drain electrolyte from sealed secondary
batteries.
Do Not drain electrolyte from vented secondary batteries unless
authorized.
