Connect one lead to the COM side of the meter. Connect the other lead to the V/ohm jack on the meter. Turn the meter to the lowest voltage measuring unit such as 5 volts or 4 volts. Make sure the meter is set on dc current and not ac current. Touch the two leads to either side of the bettery. The meter should read somewhere around 1.5 volts if the battery is good.
p.s. The direct current symbol is a straight line over a few dashes
A centimeter is about the width of a finger.
A lithium battery is going to last longer than an Alkaline but they're also quite a bit more pricey. For something like toys, if it's a common size that you use in a lot of devices like AA or AAA, NiMH slow drain rechargable batteries are usually your best bet (and last a good amount of time too). Any type of battery will be fine, except for a car battery, which may be too big.

Button batteries, AA, AAA, D and C batteries are a single cell. 9-volt batteries contain multiple cells to get a higher voltage and therefore are the shape they are. Open a 9-volt battery and you will see the cells inside - make sure you wash your hands afterwards though!
a AAA battery. Or a watch battery, or a AAAA battery, or any number of battery types. http://en.wikipedia.org/wiki/List_of_battery_types
They both involve batteries.
Many different battery brands include AAA batteries some examples of AAA battery brands include two of the biggest battery brands, Energizer and Duracell.

What are the ingredients in a AA battery?
alkaline AAA = 1.5 volts
why do aaa batteries overheat
AAA is the size of the battery, there are many types and makes of AAA battery and the shelf life for each is different.
AAA type alkaline battery is a carbon-zinc battery; the tension is 1,5 V. The electrolyte is ammonium chloride as a paste.
AAA batteries measure one centimeter wide.
