battery">Rechargeable batteries</a> have grown in use over the years as
people are looking to save money and reduce waste. There are several
types of rechargeable batteries, made of lithium-ion, nickel-cadmium,
nickel-hydride or other materials. For years, it was believed that
rechargeable batteries had the advantage of being reusable but were poor
performers compared to their alkaline counterparts. Rechargeable
batteries have improved, but they still have both advantages and
disadvantages.</p>
<p>Cost<br>Rechargeable batteries are advertised as being able to be
reused more than 500 times, greatly reducing the cost of replacing the
batteries. Some forms of rechargeable batteries will be more expensive
than standard batteries, and the first-time cost of the charger itself
must be taken into account. However, using the batteries repeatedly can
save up to hundreds of dollars a year.</p>

<p>Performance<br>At one time, rechargeable batteries were believed to
have a much lower performance than the standard alkaline batteries.
However, technology has improved in this area, to the point where some
rechargeable batteries are actually advertised to have a higher
performance than normal batteries. Nickel-cadmium batteries have been
known to perform well in very cold conditions and when excessively used,
reducing the amount of times one would need to charge them.</p>
<p>Charging<br>Rechargeable batteries can be a hassle to recharge,
especially if that forces any devices to be powerless while their
batteries wait to recharge. Also, many such <a rel="nofollow"

battery</a> have a high self-discharge rate, meaning they often need to
be charged after just being stored. A second emergency set of batteries
can solve the first problem, but the latter just complicates that
solution.</p>
<p>Uses<br>Certain types of batteries, depending on their composition,
are useful only with certain devices. Older hand-held devices will warn
against using nickel-based batteries in them and recommend alkalines
instead. Due to the cost of their materials, lithium ion batteries are
used mainly in computers and cameras. The high number of different
compositions can make it confusing for someone to decide which battery is
best.</p>
<p>Hazards<br>Some rechargeable batteries, especially the nickel-cadmium
variety, contain chemicals even more dangerous than those inside alkaline

battery</a>. This makes them a very high environmental risk and one of
the main reasons some countries place restrictions on the number of
nickel-cadmium batteries that can be used.</p>                <!--
