Buy Battery Acid from NAPA Auto Stores, product # 9002. It is a consistantly high quality product.
Specific gravity = 1.26
Pure sulfuric acid (reagent grade) is 98%
Battery acid is 1 part reagent grade to 2 parts distilled water.
Our instructions call for BATTERY ACID, which then has to be diluted.
The reason for this is that reagent grade is very difficult for the amateur plater to find, whereas battery acid is easy.
