1. [AA/AAA Rechargeable Batteries]
As the numbers of gadgets that assist our daily lives keep growing in number with each
passing day, the variety of their power sources also increases. The mostly commonly used
types of batteries are the AA and AAA type, which power up most of our portable devices
ranging from television remotes to blood glucose meters almost all small sized gadgets rely
on the AA and AAA battery types.
AA and AAA Batteries:
Probably the oldest size in battery types which is made the standard. AAs are slightly larger
in size when compared to AAA. They are available in various chemical constituents, which
differ from each other in terms of performance and durability. Here are a few battery types
and their advantages and disadvantages.
1. Lithium:
Renowned for their durability, which is displayed when they work faultlessly for
years but a major drawback gripping the lithium batteries to lack behind is the fact
that they are non rechargeable. For some devices this type of AA/ AAA is the best for
the job! Also when compared to alkaline batteries they tend to last about 7 times
longer. However there is a certain type of AA Lithium ion rechargeable battery but
that is rare to find in shops, this type of Li-ion is mostly not known of! Unlike
Alkaline batteries they do not leak.
2. Alkaline:
Alkaline AAA/AA batteries are available in both rechargeable and non-
rechargeable types but considering their chemistry it is more economical to choose
the rechargeable type. It is recommended to avoid using Alkaline based batteries in

2. devices with high drain that deplete the alkaline based batteries at a faster rate than
its normal life.
3. Nickel Cadmium:
These are the ideal choice for devices that heat up very quickly, reaching high
temperatures that other batteries can’t handle. They are priced cheaply when
compared to other battery types of the same voltage which makes them perfect for
commercial purposes.
4. Nickel Metal-Hydride:
(NiMH) work best when used in extensively used devices, because before
recharging if they are fully drained out of power then they tend to last for a longer
period of time compared to other battery types, for example it would be better to
use them in a frequently used TV remote than a hardly used digital camera. An issue
with the NiMH is the fact that in idle conditions they discharge by themselves
besides this they are environmentally friendlier compared to other battery types.
There are also differences between AA and AAA Batteries when they are pitched
!against each other, here are a few
Differences between AAA and AA
1. Generally, the AAA are smaller than AA batteries
2. AA batteries tend to carry a larger amount of chemical content that AAA
batteries of the same voltage size.

3. 3. AA batteries are designed for devices that consume more power than the AAA
batteries are capable of producing.
4. AAA batteries have a higher internal resistance compared to AA batteries so
their maximum current output is less.
5. The general belief among battery specialists is the fact that AAA batteries
generally cost more than AA but tend to deliver less in terms of power.
The AAA and AA rechargeable batteries are designed for devices with low power
consumption requirements such as toys, remote control, blood glucose meters, and
sever4al other small electronics it is a wise idea to invest into expensive rechargeable
battery brands as they tend to be worth their price and deliver a long lasting battery life
along with several recharging cycles. The best place to purchase these batteries is online at
