Types of Batteries
Alkaline: Common household batteries, AAA, AA,
C, D, 9-volt. Can contain mercury, chromium and zinc.
Lead-acid: Used in vehicles, wheelchairs, forklifts,
and portable generators. Contain lead.
Lithium: Used in some cameras. Contains chromium.
Mercuric oxide: Also known as ‘button’ batteries.
Used in hearing aids, cameras, smoke detectors, tape
recorders, electronic computers, voltage regulators, pagers, oxygen monitors,
fetal monitors, portable EKG monitors, and until recently, in cardiac pacemakers.
Nickel-cadmium: Rechargeable batteries used in calculators,
handheld tools, alarm systems, pages and as back-up power sources in medical
monitors and equipment (usually built in by manufacturer). Although these
are rechargeable and can be used many times, they eventually need to be disposed
of and contain high levels of nickel and cadmium.
Silver cadmium: Used in medical electronics and require
high-energy density and constant voltage. Contain silver and cadmium.
Zinc-air: This button battery has been developed
as an alternative to the mercuric oxide battery, though it is not mercury free.
It is used in such devices as hearing aids and electronic pagers. Contains
zinc and mercury.

- When batteries are incinerated, the heavy metals in them
can contaminate the incinerator ash and air.
- Heavy metals from batteries can leach out of landfills
and pollute water sources.
- Heavy metals have whole host of neurological effects
on humans… lead, mercury and cadmium are well-documented.
- Most, other than alkalines, are regulated hazardous waste
due to the toxicity characteristic and won’t pass TCLP tests.
- If you are going to treat them as solid waste, rather
than hazardous waste, make sure you have documentation that they have passed
- If you do determine them to be hazardous, they can be
treated as universal waste if your state has adopted the federal regulations
on Universal Waste. This will allow you to subtract the weight of battery
waste from your hazardous waste totals, and allow you some lenience in packing
and transportation requirements.
- They need to be packaged in a non-flammable container
and the ends must be capped/wrapped to prevent sparking.
(Not many alternatives… just need to recycle them.)
- Non-flammable containers
- Tape ends to prevent sparking
- Offer alkaline batteries to staff to use in Walkmans,
toys etc. as most batteries are only used once and changed our immediately
after the procedure regardless of charge left.
- Work with Universal Waste hauler
- Haulers often supply containers and you pay by the ‘bucket’
- Battery collection containers can go in soiled utility
rooms if properly labeled, proper containers, proper packaging
- Hold Battery Round-up for staff
