Powerex MH-C800S Eight Cell Smart Charger Review

Average Reviews:

(More customer reviews)I also own the LaCrosse BC-900 charger, and am glad that I own both; each has its own benefits.
Either charger is very good because:
- They charge each cell individually, rather than in pairs, resulting in the best possible charge for each one.
- They offer different charging rates, so as often as you are able, you can slow-charge the batteries to ensure they last longer, but you can still quick-charge when you must.
The PowerEx charger is better in that:
- It handles eight cells, not just four.
- A major advantage they didn't advertise, as far as I saw: it pulse-charges the batteries. Pulse-charging noticeably improves each battery's total charge capacity, in both mAh and voltage... even when you switch to another charger later on, the battery is the better for having been pulse-charged. LaCrosse doesn't do this.
The PowerEx misses on these fronts:
- It false-peaks a little more often than does the LaCrosse. This is where an actual voltagte reading would come in handy, because you could easily spot the false peak, and charge the battery again.
- It doesn't offer charge rates below 500mA; you have only this or 1A. I like the 200mA setting the LaCrosse offers.
- If a cell is deeply discharged (below .9V?), the PowerEx won't attempt to charge it. LaCrosse suffers the same problem. In such case, though, I pull the cell out and use a couple of paper clips and a charged cell... kinda like jump-starting a car... for 20 seconds, and then try putting the battery back on the charger.
Overall, I'm glad I bought this charger.
