The BC-700 and BC-1000 (I own the latter) are quite similar, but the BC-1000 allows AA or AAA batteries (NiCd or NiMH only!) to be charged at a maximum rate of 1000 ma (4 cells inserted) or 1800 ma (2 cells inserted), while the 700 charges to a maximum of 700 ma. In addition, the BC-1000 is supplied with 8 NiMH cells (4-AA and 4-AAA), while the 700 comes with none. Other features seem to be identical. The cells supplied are not "grade A" types - I'd advise you purchase "low self discharge cells" like Eneloops (available on Amazon), which will retain their charge for months vs. the weeks for standard NiCd or NiMH cells. As far as maximum charge currents, one should probably avoid the 1000 or 1800 ma charge rates anyway, since they cause more internal heating of the batteries and can shorten their life. 250 or 500 ma is a good starting point for charging and will maximize battery life. I like the BC-1000 very much, but one could buy the 700 unit and apply the savings to a set of good NiMH cells instead! You would not go wrong with either unit. Do check the Amazon posted reviews for the 700 for an excellent tutorial by NLeeEngineer on these chargers. Good luck!

Mike, Most of the time you just need CHARGE mode. That means put in the batteries and select the charging current desired (500/700mA, etc) If you want to how much capacity your batteries actually hold, use the CHARGE/TEST function. Be careful not to run this operation if the batteries are freshly charged. If you suspect your batteries suffer from reduced capacity, run the DISCHARGE/REFRESH operation. Or you can use this to refresh your batteries once every 6 months or so. Don't over do it.

They are the ordinary (high-self-discharge) type. The AA cells are not that great, as they were tested to around 2200mAh only. The AAA cells are around 900mAh.

No. The manual specifically warns NOT to try and charge Lithium batteries.

JDMoose, Are your rechargeable batteries performing normally? If they still give the same runtime as before, then maybe there is no problem with your charger. One common mistake people make is that: they assume the 'mAh' number shown after BC-900's Charge operation is the CAPACITY of the battery. It is not. This number is actually the amount of charge (current*time) that went INTO the cell during charging, not what is actually stored in the cell. So if you charge up a new set of eneloop cells that is only partially discharged, you may see something like '750mAh' in the end. To measure the actual capacity, you have to use the 'Refresh' operation.

VSG, Think of it this way: when you pump gas into your car at a gas station, the pump can only tell you how many gallons went into you tank. It has no way to know how much gas is already in you tank, nor how large is your tank. It just kept going until the 'tank full' signal is detected. That's exactly how the BC-1000 (or any other smart charger) works. In Charge mode, it can only tell you how much charge (current*time) went INTO your batteries, not how much is already in there. To measure the actualy capacity remaining in the battery, you have to use Discharge/Refresh mode.

Not yet. Try kicking some life into it using a regular charger for a few minutes. The voltage has to be above 0.9v for the La Crosse to recognize it as a functioning battery. See page 11 of the instructions. If it still reads 'null' - recycle it. I have 'rejuvenated' some, not all.

My "package" contained 5 re-chargeable batteries and 8 adapters.

No, it only fits AA and AAA batteries. It comes with C and D size adapters that allow you to use AA batteries in devices that require C or D. You put a AA battery into the C adapter, and if needed you can then put the C adapter inside a D adapter.
