As long as there will be batteries, you will need a charger to recharge them. However, finding the right kind of charger, is the quest of many, such as myself. Having multiple chargers means multiple and different charging variances as well, and this is not recommended.

I've used the NEXcell NC-20FC for about a few months now, and I can honestly recommend it.

At first, I was skeptical because I am a die-hard MAHA user. However, NEXcell has done a pretty good job with this charger. A little tune starts up whenever you plug it in to the AC. It plays It's A Small World. It will certainly wake you up in the middle of the night or early in the morning. Kind of cute, and you only have to press "Button I" on the front to turn it off (the second button apparently does not turn off the music feature as per the manual). You can also have the musical tune notify you when the batteries are fully charged. This actually comes in handy in case you're doing other things around the house and want to use the batteries as soon as they are done, but don't want to stand over the charger for a few hours in order to do so. If you don't want to hear the musical tune.

NEXcell's charger is straight forward and easy to use. Incorporating dV, dT, Tmax, and "Timer Technology", the charger comes with the features you need to be sure your batteries are accurately charged and discharged.

The NEXcell NC-20FC comes with an AC Adapter and a 12V Car Adapter. Here are the charging specs:
