<pre wrap="">Experience with after market D7 batteries?
We bought ten 800 mAH NiMh batteries for all of our D7's here at the office.
None will charge in the D7 drop-in charger without going to BLINK mode
after a charge..
Are they charged? Or is this ano-charge error condition?
Maybe it just doesnt like the 800 mAH capacity since it expects 600 mAH?
THey do seem to work after a charge, but not sure how long. Before I
did extensive testing, just thought I woiuld ask of others experience
with the drop-in charger and off-brand batteries.

Also they are nearly impossible to attach to a D7. The plastic
housing is not well matched to the intricate holding system on the
back of the D7.

Get the Batteries America back for AA cells instead. The pack
holds 6 AA MNiH rechargeables. Or if you need extended runtime in
the field without an opportunity to recharge, yoiu can put 6
standard AA non-rechargeable alkaline or lithium cells. Then
get a couple of cards of 1800 mAH Sanyo Eneloop rechargeble MNiH
AA's at Costco. Or get the 2700 mAH Sanyos at Batteries
America. <br>
<br>
The pack is slightly larger front to back than the original and
the color doesn't quite match (it's black instead of the Kenwood
dark silver-grey), but you get almost three times the run time of
the OEM pack at 1/3rd the cost. <br>
<br>
The one disadvantage is that you have to remove the batteries from
the pack to charge them (i.e. no drop-in charging). Or perhaps
it's an advantage since you can't accidentally charge primary
cells if you happen to have them in the pack instead. <br>

Hi Steve, Bob,<br>
<br>
I second the suggestion for the BT-11h from Batteries America. I
have one with 2650 MAh batteries in it, and it will run for over a
day at beacon rates, and that includes driving the little GPS that I
spliced into it.<br>
<br>
As for charging, since I only intend to use rechargables, I hooked a
little wire into the case to short out the blocking diode, and the
radio does an acceptable job charging the higher capacity
batteries. It also gives me a diode's drop worth of extra power.
The only problem is that the D7 doesn't have any sort of effective
indicator of battery charge, so I just stick the charger plug into
the radio every so often to top it off. Probably not the best
treatment for NiMH batteries, but it's worked so far. It's slower
than C/20 rate (more like C/35) so shouldn't damage anything.<br>
