The Base 2 generates a lot of heat which degrades the batteries over time. Either a dedicated charger or the 993 cradle are better.
Per GRJ's suggestion. I bought a Tenergy charger that monitors each NiMH battery's charge individually. The one I bought is discontinued, but there are lot's of good options now that also monitor each battery individually.
