Energy charger series

The microcontroller-monitored charger of Energy series does not require any control elements and, thanks to the fully automatic control, its handling is clear and easy. You can charge all five major battery sizes, also mixed. The battery level prior to charging is irrelevant. The charger is suitable for all rechargeable batteries (NiMH/NiCd).

Ansmann Universal Desktop Charger

High-tech charger with high charging current and perfect charging control

Highlights of the Ansmann Energy 8 Plus

1. Charging the batteries:

Charging option for 1-6 Micro AAA / Mignon AA, 1-4 Baby C / Mono D, 1-2 9V Block NiCd/NiMH rechargeable batteries.

2. Maintaining and refreshing the batteries:

The device automatically detects ailing rechargeable batteries, and initiates a refresh program which gently 'revives' the batteries.

3. Automatic shut-off:

State of the art microprocessor-controlled charging technology with multiple overcharge protection guarantees optimally charged batteries and a gentle charging process.

4. Quick charge:

The Energy 8 Plus automatically determines the optimal charging current for the inserted batteries and loads them with up to 1000 mA in a rapid charging process.

5. Individual monitoring:

With the Energy 8 Plus each round cell (of any size) can be placed in any charging slot. Each battery is individually monitored during charging, and individually charged to its maximum capacity.

Intelligent charge control

After inserting the batteries, the charger starts an automatic diagnosis and a quick capacity test for about five seconds. Depending on the condition of the battery, the device selects a gentle pre-charge and/or refresh program, or initiates the actual charging process. The refresh mode restores performance of rechargeable batteries damaged by storage or memory effect, and prolongs their life cycle considerably.

Once a battery is fully charged, the charging process is automatically stopped and switched to trickle charging (buffer charging with current impulses). This feature ensures optimum performance and counteracts the self-discharge of the battery. The battery can thus remain in the device until it is used. A clearly arranged LED display shows the current program mode for each charging slot separately. Should a non-rechargeable or defective battery be inserted accidentally, this will be indicated by a flashing red LED.

The Energy 8 Plus is designed for worldwide use.

Style Name: No batteries included
I ordered this product and the bottom completely melted upon first use. I used 4 Tenergy AA batteries on first charge attempt. I contacted the seller who referred me to the manufacturer. I called the New Jersey number (the US office) and spoke with a woman who took my information and gave me their tracking information to send it in for a replacement.

2 weeks and nothing. No email correspondence, nothing. I called them to inquire, and they informed me that they hadn't received it and will have to "look for it". The tracking information on Fed Ex website stated they received it 2 DAYS after I sent it. She said she'd call me back. Didn't hear back for 2 days. Emailed them. Email ignored. Had alot going on, forgot about the charger. Remembered 2 weeks later. Emailed them. Email ignored. Called them. She said she couldn't find it and that she'd "make an exception for me" and ship it out that day.

2 weeks later. Nothing. Emailed, no response. Called them. Left message. Didn't get back to me. A few days later, called them again. Threatened to write the German headquarters and tell them about my experience with their US office, including my fed ex tracking number to prove that they received. Dead silence on the other end, and then "You'll have your shipping tracking number by the end of the day".

Another week passes, I received my new unit. Put in 2 AA Tenergy NiCH batteries. The lights appear red to indicate charging. 2 hours later: red red red. Never turns green and the machine smells like it's about to melt again. Months of inconvience and an utter waste of money.

Ansmann corp: I think it's time you wrap things up.

JB - You shouldn't have thrown away all those supposedly "bad" batteries just yet. This charger, and most others, are too stupid to identify the batteries (50% +) that can be "rescued". Just because this charger doesn't have the ability to make those batteries "come back from the dead", much less tell them apart from truly dead ones, doesn't mean those batteries are necessarily permanently "bad".

Many dead batteries can use a short (NOTE: LESS THAN ONE [1, single, lone, only] SECOND) "bump charge" to bring up their standing voltage, meaning, "a charge that can be held", to a level that even this charger sees as a "good enough" battery worth charging. Any charger can then charge it normally.

BUMP CHARGE PROCEDURE
Take a known-good, fully charged battery WITH THE SAME VOLTAGE RATING and then, FOR 1 SECOND, ONLY, short the 2 batteries together, plus end to plus end, minus end to minus at the same time. DISCONNECT AFTER 1 SECOND. Retest the "bad" battery again. Repeat this process up to five times or until the "bad" battery can start charging normally. This procedure is not hazardous to the good battery if the bump charge duration is limited.

If, after, say, 5 bump charges it still reads "bad" then it probably is bad=dead and dispose of it. Don't forget to recharge your known-good battery !

This is a very good charger for re-chargeable batteries. There's no LCD readout for capacity and all the other fancy stuff that others might have. The LED light read out for the different status modes while charging helps.

I had a bunch of Duracell batteries that didn't hold their charges for a long time but this charger managed to salvage a few of them by reconditioning them. I've heard many good things about the eneloop batteries from Sanyo so I'll be switching to those.

I'm happy with my Ansmann charger, it does it's job safely as allowable for the batteries.

The Anssman is an easy to use charger when compared with similar offers from Maha and La Crosse, but doesn't offer much control.

It has nice features like the ability to renew batteries, detect faulty ones and such. Altough it seems to fail to charge nearly completly depleted batteries.

If you're after an easy to use charger with solid quality and features, this one is for you. But if you like to see more info about the batteries and more control over charging settings, take a look at Maha and La Crosse offerings.

Just plug and play. No wall wart. 4-8 batteries (depending on your mix of C/D to AA/AAA), plus two dedicated 9V bays, all functioning individually, and the thing just works. Plop in a battery, it figures out what it is, if it needs "refreshing", refreshing if needed, then charging at an appropriate speed - and it charges my AA and AAAs pretty fast (couple of hours or so). You can leave the batteries in there as long as you like. Alkalines are sensed and not charged. Polarity mistakes are similarly treated. The slide rails that contact the negative terminal are smooth and sturdy. Very nice. No lid, but my other charger's lid just got in the way anyway, so who cares! Get this charger if you like it simple. Oh yeah, each battery gets its own status light too - let's you know things like "refreshing", "pre-charging", "charging", "charged", and "error". Smart.
