（I have a question on gel-type batteries.）
Q.
I know that generally speaking there are two types of batteries, i.e., a non-spillable (dry) batteries and a spillable (wet) batteries. Both are classified as corrosive material. I also know that non-spillable batteries can be handled as ?gnot restricted?h while spillable batteries must be handled as ?grestricted?h.
Recently I have learned that among the non-spillable batteries, there are two types. One being the conventional liquid type, and the other the gel-type. Here comes the question. May I consider the gel-type batteries as ?gnot restricted?h? Or, should I consider them as ?grestricted?h? Is the understanding, non-spillable = dry battery, and spillable = wet battery correct?

A.
In reference to gel-type batteries, the changes in DGR 51st Edition versus DGR 50th Edition are in 9.3.15.3 where the paragraph has been expanded, and the Note referring to gel-type batteries deleted. Also in 2.3.2.2 and in Table 2.3.A, a similar note concerning gel-type batteries had been deleted.
Gel-type batteries are categorized as one type of non-spillable batteries. By virtue of SP A67, it is exempted from being categorized as UN2800 Batteries, wet, non-spillable. SP A67 spells out that if the conditions of PI 806 are met, the battery May be handled as ?gnot restricted?h.
As a reply to the question raised, gel type batteries still remain as one type of Batteries, wet, non-spillable but is exempt by application of SP A67. The equation, non-spillable = dry battery, and spillable = wet battery is incorrect. There are two types of wet batteries, the spillable and the non-spillable type. Among the non-spillable type, there is the gel-type batteries. Gel-type batteries not satisfying the provisions of SP A67 are considered as ?grestricted?h.
