Roomba 400 Series Battery:
Grey Roomba 400 Hard Case BatteryNiMH Hard Case Roomba Battery
As you can see, the 400 series model has a few more selections. It comes in 3 versions:

1) Gray NiCD Hard Case (Pictured: Left):  (*No Longer Offered -- NiCD has memory effects & lower capacity when compared to NiMH types). This is what is originally used in some units. Battery life on these do not last long.

2) Yellow NiMH Hard Case (Pictured: Right): This is essentially a plug-n-play battery; just remove the old battery and replace. This battery is made up of NiMH cells, and is rated at 3.3Ah capacity. The difference between this case and the grey one is the higher capacity. This yellow pack verson will provide almost double the runtime of the gray version. Despite the longer runtime, both Yellow and Gray versions are the exact same physical size (in terms of dimensions).

Any of the 3 above are compatible with (but not limited to) the following models:


Roomba 500 Series Battery:

1) NiMH Version (Pictured: Left): This is a plug-n-play battery; just remove the old battery and replace. The original Roomba charger is fully compatible. This battery is made up of NiMH cells, and is rated at 3.5Ah capacity.

2) Li-Ion Version (Pictured: Right):  Taking advantage of the latest battery technology, this Li-Ion version is even better than traditional NiMH type batteries. It deliver up to 56% longer runtime, and is more suitable for storage or the minimum use of some Roomba owners. While it initially costs more vs NiMH, you will replace the batteries less often and save more in the long run. This is a direct replacement for your previous NiMH battery and is compatible with the Roomba charger.
