Should I leave these on the charger (sometimes for several days like I do my Topcon GPS gear ~ see last photo below)?
I only ask, because lately it seems that when I do not, then they do not seem to last long when I do get around to using them.
However, when I put these little green "nuon" AA & 9-volt batteries on this charger, they get kinda warm overnight, so I do not leave them on the charger. But, they seem to last longer in the field when I do get around to using them.
And, just for further comparison, I leave my Topcon GPS stuff on the charger for days with no apparent trouble. Mainly because the data collector loses the charge just riding in the truck for one day with no use whatever...?

I did not have god luck with charging through the BanTams. I don't know if I have a wonky charger or what, but I had to replace the included "green wrapped" batts with some Energizer rechargeables. I can get 2~3 decent days with them. I take them out of the BanTam and put them in the Energizer wall charger. Yeah... it takes about 5 seconds, but it's worth it. I also bought some 9V Tenergy's (or something like that) off of ebay or Amazon or buy.com not long ago. Today was the first day that I have had one run out on me. I had an extra one at the ready, so it was no big deal.

I noticed the same when I went to the wall charger.

My Carlson Surveyor+ will do the same. For all I know it's the clock running it down. I just get used to plugging up everything every night when I come in. I just count myself luck this is the old NiCad crap that you had to run out to the very end or else you'd burn memory bubbles on the cells.
I was told to recharge batteries as soon as you can, take them off the charger and store them, then if they have to sit awhile recharge them right before you need them again.
Brad:
I have a Topcon FC200 that dies just sitting around too. I just take the battery out after it is charged then put in back when I need to use the unit, seems to work.

The rechargeable batteries used in the BanTam units are Nickel Metal-Hydride batteries. They are similar in some respects to NiCad batteries, though the same size battery in the Ni-MH provides significantly longer run time than a NiCad.
The batteries in the other Topcon equipment shown are Lithium-Ion batteries. They like to be charged and it is normally to leave them on the charger for extended periods.
I have no idea how long you've had your BanTam units but any such batteries have a useful life span that is defined in part by age but also in the number of charging cycles they have been through.
They just stuck a sena bluetooth adapter in a plastic case and are charging more for it? Seriously?
