• Hard, durable plastic casing
• Individual, microprocessor-controlled charging. (-) delta V control
• 5-hour safety timer
• 75mA per channel, 50% faster than previous model. (**see below)
• Switch to trickle charge when cell  completely charged
• Bad cell detection
• Reverse polarity protection
• Optional DC adaptor for on-the-go car charging
• UL approved power supply
• Two-year warranty

It is important to realize that 75 mA to 80 mA should be the maximum charge current  to avoid overheating of 9V cells and preserve optimal recycles.  Although there are a few other chargers on the market that boast 90 mA or even 100 mA charge current, these chargers can damage high-quality 9V NiMH cells and significantly shorten battery life cycles.
