Bescor NMH54XLRNC 12v Nickel Metal Rechargeable Battery No Charger. 6 Ft. Cord with 4 Pin XLR. 4.5 Amp Capacity
NMH batteries are rated to give 500 to 1,000 cycles in normal usage. These batteries can be stored either discharged or charged. If stored fully charged they will self discharge over time. However, storing the batteries in a cool, dry place (refrigerator) will slow down the self discharge process. It is best to use these batteries at least once every 6 months., otherwise the internal organic materials inside the battery will dry out and the battery's performance will deteriorate. Bescor's automatic chargers, models NMH-ATM and NMH-ATMX are recommended for maximum battery life.
