These batteries are used in the inexpensive radio slave triggers sold on ebay and at other sources.

These are high quality, fresh date, Sanyo "Ultra" batteries, not the off brand batteries that typically ship with these radio slaves when new.

A fresh high quality battery in the transmitter often cures functional issues with these radio slaves.  If you are experiencing issues with the sync speed creeping slower and slower, or the range shrinking, a fresh Sanyo transmitter battery may help.

Even if your radio slaves are working properly, you should always have a spare battery or two on hand.

This battery replaces all of the following battery designations:
23AE, 23A, A23, V23GA, E23A, K23A, V23GA, GP23A, 8LR23, MN21, N21, LRV08, L1028, RV08, MS21, 8LR932, VR22, 8F10R, EL12, LRV08

This battery is very easy to install.
