There is so much to learn from Experience with some of these different charging ideas an d some will ruin your batteries from what I have seen. The factory charger for the Explorer and the GT do put out more than the older Sovereigns charger did, but that has a lot to do with them using Nickle metal hydride's batteries and larger capacity batteries. The stock charger work good for charging the batteries up, but take a little longer to do this and feel Minelab done this for a reason so you get max out of your batteries. Too high of a charge will get your batteries hot and the 1 amp will cook them and I know your life of the battery will be shortened quite a bit. The charger I like is one of the old Sun Ray SR12 chargers and think the highest charge rate is around 350 uA as it takes a little while longer, but when fully charged it goes into a pulse trickle charge. Also what is nice is you can discharge the battery to a safe level and then it will automatically charge it to the correct voltage and go to trickle charge. Been using this battery charger since 1997 and never ruin a battery yet and many are still running in the older Sovereigns. Now I tried a charger many said was so good that would charge the whole pack at once, but it ruined many batteries and even blew up a 9 volt battery on it as it just charged too high for the battery. That charger that Critter mentioned I have also and did ruin a couple of batteries with it as i didn't get a owners manual with it and didn't know how to set it up correctly, will agree it is a good charger, but not one for those that just want to plug in a charge and do know anything over 500 uA will charge fast and make the pack hot.
I also tried several that charges each battery separate and the one I have will charge 8 batteries separate and as they are fully charged they will quite charging until all are charged, but feel it charges too fast of uA as the batteries get hot and notice some are getting bad before they should.
Don't know how much my solar lights charge but the same batteries I use in my detectors are in it and been running over 3 years straight and believe they are a low charge rate and work as good as new, those I do on my single charger I notice after about 10 charges at the higher rate will not last that long, so as you see I am not for the higher charge rate unless the battery is made for it.
