Maha has released one of their most exciting products ever, the MH-C801D. Announced August 15th, 2005, and now currently available from major electronics dealers, is an Eight-Cell 1-Hour AA/AAA charger. Yes indeed, this is a 1-hour charger and you can have up to EIGHT batteries, either AA or AAA, in any configuration. The cells interact with the charger independently of each other, meaning you do not have to keep a mental note of which batteries have most of their charge, some of their charge, or no charge at all. The MH-C801D is also one of the best deep conditioners I've used ever, and we'll get to that part later in this review. For now, let's discuss the MH-801D.
A Professional High-Quality Charger
Maha has once again created a high-quality product for professionals and those who need a large-capacity charger. Several charging options are available: Rapid Charge, Soft Charge, and Condition. The heavy duty international AC power adapter requires no transformer because Maha has made an adapter which can accept foreign electronic currents and voltages. All you have to do is obtain the proper plug (which Maha does supply on their website) and are available at places such as Thomas Distributing. The design of the MH-C801D is a durable, made-to-last construction, from the charging unit to the supplied rugged international AC adapter.
Multi-Status LCD Display
As you can see from the above image, Maha has gone to an LCD display for this particular model, instead of the basic Green, Orange, and Red LED lights you would normally experience on their other models. Much more information can be displayed about the battery status with an LCD integrated with the voltage detections and microprocessor. For an eight-cell charger, an LCD display was a wise choice. Just imagine 8 red and green lights flashing independently. Your neighbors would think you were holding a Christmas party!
Maha's own microprocessor can detect voltage differences within 0.001V. This assures your new batteries and really old batteries, will each receive the amount of charge they need. All of this happens independently in each charging cell.
Deep Conditioner & ISPD
Maha's own ISPD (Integrated Safety Protection Device) prevents short circuiting of batteries, as well as refusing to charge alkaline batteries and battery polarity reversal (i.e., you put the batteries in wrong). Additionally, the MH-801D has one of the deepest conditioning cycles available, restoring batteries to their best operating performance. Yes, it does take about 14 hours for a full conditioning, but it works (more on that later).
The charger's circuit board is made from FR-4, with a UL 94V0 rating. This is a high-grade fire-retardent material which is also moisture resistant. Charging your batteries in the winter, when condensation is at its highest, can lead to potential issues, and it's nice to know the MH-C801D has this grade of material to prevent condensation from accumulating on the charger's sensitive areas. And even if you're in a geographic area which doesn't have a "winter" per se but high humidity, the MH-C801D's charger is also resistant to accumulated moisture. This makes the 801D a travel companion.
