I just read on another forum that one of the concerns about the GPs and using the GP charger is that the flimsy battery door might break and the metal connection on the inside of this door will start to wear down by taking the GPs in and out. Any truth to this? Also, I found these Sony's listed on Ebay. Does anyone have any experience with these; the batteries are not the same as the orange ones that were in my recorders or that are sold on minidisco.org: http://search.ebay.com/nh-14wm_W0QQfnuZ1QQ...fsopZ3QQxpufuZx Thanks again. I'm not trying to drag this thread on forever; just trying to avoid a situation where students, who is just learning to record, find themselves with dead batteries. Take care.

Thanks for the replies. I purchased the recorders from Sam Ash. The batteries are Sony rechargeable N-14WM(A) Nickel-Metal Hydride with Stamina written on them (which is ironic). It's safe to say that they did drain all the way down since the students don't keep track of battery life. The batteries were never removed from the units other than when I took each one out to see if there was corrosion on the top. So, what do y'all recommend since I don't have the budget to keep buying $25 batteries that are going to last one year. Should I just use the double-A attachments instead or will the GP gumsticks last like the battery in my MZ-R50 that will last for 5-6 years at least? Finally, if I do buy the GP batteries, can't I just charge them by charging the full unit with the AC adapter or do I actually need a separate charging system? Thanks again.

Hi. I am new to the forum and have searched to see if this issue came up elsewhere but did not see anything. I teach an audio doc class and use MiniDisc recorders in the class. Last year I purchased 5 MZ-M100 recorders. The batteries on all of these recorders are already dead; they will not re-charge. The recorders will play and record if plugged in but are dead when not running on the AC adaptor. So my question is two-fold: (1) did anyone else have problems with such a short battery life (by comparison my MZ-R50 from 1999 is still doing great) and if so was there any way to get Sony to provide new batteries? (2) Any recommendations on places to get cheap batteries? Thanks.
