This plastic battery enclosure holds eight L-16 batteries, such as Trojan, Interstate, Surrette Rolls and others. The enclosure includes a bottom drain fitting that allows you to wash and rinse off the batteries. There are three pieces to this enclosure: the bottom pan, the middle section and the lid. The middle section slips inside the bottom pan to reduce the size of the package for shipping. It also allows you to put the batteries into the bottom pan, which is 9 inches tall, before the middle section is installed.
