With the ACR Electronics Battery Adapter, the hunt for those heavy 6-volt lantern batteries is over. Instead, this adapter allows the user to replace those lantern-style batteries with 4 common D-cell batteries. The adapter replaces both spring- and screw-post lantern-style batteries, while allowing equipment to pass the same Coast Guard drop tests. The 4D6V Battery Adapter has a suggested retail price of $4. ACR Electronics, Inc., Fort Lauderdale, FL; (954) 981-3333; Fax (954) 983-5087; www.acrelectronics.com.
