After several years, the battery in my cordless drill is dead.

As is often the case,
a replacement battery costs more than the whole drill !

The drill gets occasional light-duty use around the house.

Can anyone suggest a replacement brand ? ( less than $40 )

Do you really think someone can recommend a replacement brand of battery for a
completely unknown drill? Is it a 3.2V drill or a 36V drill? A harbor freight
cheapy or the most expensive brand?
