5 Operational Modes
- Charging current adjustable from 0.2A to 2.0A in 0.1A increments.
- Useful when battery needs to be recharged without determining the capacity of the battery. It should be used on batteries known to be in good condition and have been in continuous use.
- Discharging current adjustable from 0.1A to 1.0A in 0.1A increments.
- Useful for analyzing the amount of charge stored in the battery. Battery not recharged at the end of the cycle.
- Performs a charge-discharge cycle for a programmable number of times. Charging and discharging rates are also selectable. At the end of the cycle, a final recharge is applied. Max. 12 cycles.
- Suitable for cycling the dormant batteries to recover capacity.
Refresh & Analyze Mode
- First recharges the battery, rest for two hours, discharges, rest, then recharges again. Charging and discharging rates are programmable.
- Reports the discharge capacity at the end of the cycle.
- Useful when the battery capacity needs to be determined. Also useful for battery with degraded performance.
- Applies a 16-hour 0.1C charge (0.1 times the capacity of the battery), rest for one hour, followed by a 0.2C discharge, rest again, and finally a 16-hour 0.1C recharge again.
- This process is also known as “Forming Charge.” Also recommended with batteries that cannot be rescued by the Refresh & Analyze mode.
- The process follows the IEC standard for determining battery capacity.

There was a problem filtering reviews right now. Please try again later.
I must say that this charger does have a learning curve, but it is small, overall; and there are enough reviews of this charger-analyzer out there on the net and on YouTube the learning curve is pretty shallow overall.
One thing the directions did not make perfectly clear but the reviews out there did is that you have the ability to charge only one, or two, or three or four batteries at a time. They can be different sizes AND they can be NiCad or NiMH and you can be performing different functions with them too. Every slot in this charger is independent of others around it.
This is the nicest, most comprehensive and most flexible battery charger I have ever used in over 25 years of using rechargeable batteries. I have seen battery technology really change and advance over the years and finally there is a charger available that is as advanced as the kinds of batteries we now have to choose from for our varied uses.
This is a five star unit and I have been recommending it to all my friends who use rechargeable AA/AAA Nicads or Nickel Metal Hydride batteries.
P.S. I forgot to write the following useful charging tips: Charging rates for batteries are classified as C.1, C.2, C.3, and so on.
To make this easier to understand think of each C as a 10% i.e. C.1=10% of the battery's capacity. For example manufacturers recommend that you don't charge batteries at more than a C.3 rate, so for let's say a 2000 MAH AA NiMH battery this mean 30% of 2000 which equals to 600 MAH; in my humble opinion even if you want to charge your batteries fast you should not exceed C.5 (50% of battery rated capacity). When it comes to charging batteries the faster you charge them the hotter they will get, and some cheap brands of batteries are more likely to leak; also the hotter the batteries get when being charged the shorter their life cycle becomes i.e. the number of times that they can be recharged. So the bottom line is that those so called 15 minute chargers kill your batteries very fast and that is not a good thing specially if you have invested in high-end batteries such as the eneloop pro. I have tried to make this as easy to understand and hope that it will be of use specially to those new to using rechargeable batteries.
I have two of theses units running and have well over 100 Eneloop Pro AA High Capacity Ni-MH Pre-Charged Rechargeable Batteries https://www.amazon.com/gp/product/B00MXCIK32/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1
We use them in Wireless and non Wireless trail cams on large property's we maintain,
I always start new batteries with the break in mode takes about 36-40 hrs onetime when you 1st get the Eneloops then just regular charging after that.
Best chargers out there just set down and read the booklet that comes with it and yes you may need to take time and read it again, We leave the booklet out with the chargers to reference if needed.
