IROBOT Roomba 4905 High Capacity 3500mAh Battery Replacement non-oem is cheaper replacement battery for IROBOT Roomba robotic vacuum cleaner then original IROBOT battery.
Technical Details of IROBOT Roomba battery replacement:
According to the reseller, battery is 100% compatible with original battery – it may be charged using the original charger and used as original battery in everyday operations.
NiMH batteries are less susceptible with charging and discharging cycles when compared with NiCd batteries and according to the ePowerEngine, charging and discharging cycles have no negative effects on the battery.
However, when you get this battery, you should charge and discharge it fully several times. This way, your robotic vacuum cleaner will operate longer and battery will keep it capacity for much more charge/discharge cycles. IMHO, although this is NiMh battery, it should be regularly fully charged and discharged in order for battery to last longer – of course, this is not always possible, but it is a good practice to fully charge it and discharge it maybe very 2-3 months.
So, if you are going to buy this battery, it would be nice to have good Ni-Mh charger/discharger to keep this battery pack healthy for longer period of time.
Many people complain about non-oem batteries and the way they behave – they often have memory effect and self-discharge characteristics just like old NiCd batteries. This battery comes with 30 days money back and 1 year warranty – more than enough to give it a try. After all, it is much cheaper than new robotic vacuum cleaner.
