Wireless: What types of 9V batteries are recommended for PRC-2 IFB receiver use?

Apr 06, 2019

Question:  Can you advise me if I can use 9V NiMH type batteries in the PRC-2 receiver?  I'm trying to save on the cost of daily use of alkaline and or lithium non-rechargeable type batteries, but I'm concerned that the rechargeables will not provide enough current over time to be useful.
Answer:  The battery you use in the PRC2 receiver should be a 9 Volt alkaline or lithium, available almost everywhere. The standard current draw from a PRC-2 receiver is approximately 60mA. 
--Alkaline batteries will provide up to 8 hours of operation.
--Lithium batteries will provide up to 20 hours of operation.
--Carbon zinc batteries, even if marked “heavy duty” will only provide about 2 hours of operation.
--Rechargeable 9V (actually 8.4V) NiMH batteries usually are rated at 200 - 250 mAh will only operate the receiver for 1.5    hours or less and not recommended. 
--Lithium-Ion 9V batteries will provide 4 to 4.5 hours of operation if they are rated at 500 to 600 mAh type discharge capacity. 
Make sure your batteries are marked “alkaline” or “lithium.” Short battery life is almost always caused by weak batteries or batteries of the wrong type.
