hello lookinf for some new aa recharagle batteries can someone tell me if you have used any of these batteries and were they good or junk lenmar 2700mah power ex 2700mah tennergy 2600mah ultra pro 2700mah thanks for any help. currently using energizer2500mah.
A good way to choose is to first look at how you use the scanner.
If you listen all day, day in day out, then the low-self-discharge types may not be best for this application since they typically top out at 2300 mah capacity. In this case, regular high-capacity nimh's, like 2500's / 2700's would be ideal - but with their higher level of self-discharge, if you don't use them for a week, they will basically be at the 2300mah level mark just sitting around.
Basically, for regular nimh - the higher the capacity, the higher the self discharge. If you use them right away, you'll get the most out of them.
Low-self-discharge is fine for scanning - and ideal if you only listen casually. They typically top out at 2300 mah or so, but will retain what they have for a longer time, so if you do casual listening every now and then, they are ideal whereas with regular nimh's and casual scanning, you'll be recharging much more often.
Energizer's regular-nimh rode the high-capacity wave starting a few years ago, but due to high self-discharge, or low cycle-rate problems, they have been dropping their regular nimh capacities back to 2300 mah. Their current Chrome-green rechargeables at 2300mah are actually doing great service when tested on a Maha. Anything higher in capacity, or old shelf-queens like the silver-green (easy to confuse with the chrome-green packaging), 2450's, 2500's or higher is something I'd avoid if you see them around from Energizer - unless you get them at a fantastic price and don't mind just burning through them.
I personally have not had much luck with Lenmar, and stick to the CURRENT 2300mah chrome-silver energizers for regular nimhs, or low-self discharge like Sanyo Eneloops or Powerex Imedions (the LSD versions of the regular Powerex). I have not tried Tenergy brands. I use Powerex 2700's for regular nimhs' but ONLY if I'm going to use them right away.
