NiCad
batteries can be a great financial and ecological investment
if you know a little bit about them.
New batteries
require a few charging and discharging cycles to come up to full
power. When you receive your new batteries, charge them overnight.
Next, allow them to drain. You can put them in a radio until it
shuts off or no voices are heard, or put them in a flashlight
until the light is very dim. Then recharge the batteries fully.
This procedure should be repeated two more times if you want to
get the full output of your NiCads as soon as possible.
Do not overcharge NiCad batteries. Excessive charging heat
will substantially reduce their life span.
NiCads slowly lose their charge even without use. It is best to
charge them up for an hour or so once a month if you are keeping
them for emergency use. You can store NiCads indefinitely without
ever charging them. If you want to use the stored batteries treat
them as new and follow the charging and discharging steps
described in the second paragraph.
NiCads can develop a memory. For example, if they are
constantly drained only half way and then recharged they will lose
some of their capacity. For this reason it is best to fully
discharge them a few times a year so your batteries will retain
their full capacity. This can be done safely by putting them in a
radio or flashlight, as stated above. However, it is best not to
drain NiCads fully. If you have a volt meter bring them down to
approximately 1 volt.

There is one more thing to carefully watch with NiCad when you are
charging more than one battery at a time. If one of the batteries
has a charge much lower than the others the battery that has the
low charge will sacrifice itself to benefit the battery with the
higher charge. After a few charge cycles the weak battery may
permanently lose its full capacity. After many charge cycles this
battery may be permanently dead. The way to prevent this from
happening is to check your batteries with a tester before and
after charging them. Be sure batteries that are low are charged
separately until they equalize.
At least once a year clean the contacts on your batteries, the
electronic device and your charger. A thin black insulating film
builds up and prevents proper electrical contact. To clean the
contacts use the eraser on a common yellow pencil and gently rub
the contacts, followed by a rub with a cotton swab dampened with
alcohol.
No matter how much a manufacturer brags about how fast their
batteries will charge, the fact is the slower the charge the
better. You can substantially reduce the life span of a NiCad
battery by consistently charging at a high rate.
Dont waste your time and money with lower capacity NiCads
Most of the time our NiCads provide more power. The power increase
with our batteries is generally 60% for AA
size batteries and 220% for D
size batteries. This is more power than most NiCad batteries
found elsewhere.
