How do you tell (AA) Ni-Mh v ALK Batteries

Postby Bumble_Bee » Thu May 03, 2018 9:59 am

Hello,

I'm looking to get some rechargeable batteries for my Uniden scanner from Argo (Energiser or Duracell).

There is a switch to change from ALK or Ni-Mh depending on what battery type I am using. (I can't see [without buying] what type the energiser or Duracell are - other than that they are rechargeable [Is this the key?] - will it tell me on the box?)

I also know not to use ni-cd batteries either I think.

Also - does the number of mAh matter - currently got the stock 2600mAh but the ones above range from 1300 to 2000?

Thanks for any help.

Hi
It's very easy..Ni-Mh batteries are the rechargeable ones,and Alkaline aren't.So depending on which ones you put in your scanner,set the switch accordingly.
I use 2500mAh in mine,Duracell Recharge Ultra from 7dayshop.com.Cheaper than most places too..I've sent you a PM with the link
Basically the higher mAh number,the longer they should last from being recharged,and you're correct to avoid ni-cads.I wouldn't go higher than 2500mAh,because as far as I'm aware,2900s are slightly bigger in size and may not fit in your scanner.

Also you will find AA Rechargeable cells are 1.2v and not 1.5v like a ALK.

Excellent - Thanks for the recommendation - all ordered.

Cheers thelad - my battery knowledge is increasing by the hour. :-) (That explains the need for the switch in the unit as well [tick].)

Another point to bear in mind is you'll need a wall charger for them..if you haven't already got one.
I've found it's a waste of time charging them in the unit,at least in my 75 and 125XLTs.The system just isn't accurate enough.

I have replaced the batteries in my uniden 125 for Lidl rechargeables at 2400mah, they are made in Germany and stay charged for upto 12 months. Great price at £2.99 for 4 AA 2400MAH batteries.
