Nice one Robert... Tripped over this site about Charging : http://batteryuniversity.com/learn/article/how_to_charge_when_to_charge_table Mentions that when Fuel-gauge becomes " erratic "Li-ion`s do need to Discharg/Refresh every 1- 3 month . When recharging I always press the Refresh button on the MH-22 , so far so good ,but I`m beginning to have doubts now.

Well to be honest, I am probably worlds worst organised charger. If I decide to go out on an expedition it's usually totally unplanned drop of a hat and I'm off. So I end up having a rush round to bung all the batteries on charge, check the cards, chuck the lot in the back of the car and away! I have an inverter, which I haven't used for several years, 300 Watts, nicely enough for battery chargers. So I am going to wire it into the car soon, maybe even tomorrow. I am hoping to get back up to Skye in a week or so, darkest moon, but I don't think there are going to be any cloudless skies. So, do I put the batteries on charge now, or wait a while... Thinks I will wait a while.

Pressing that Cal button on the MH22 results in a deep discharge, don't press Cal unless the Cal light illuminates. Before relying on internet information, READ THE MANUAL for the device, the manufacturer really does know how best to use its products.

Geoff , Thank You, I did not know that the Cal. button would let me know , I thought it only lights up when I pressed it , Your Advice is deeply Appreciated

Inverter should work off the cigarette lighter especially as it is only 300W. Some camera battery chargers have 12v input as well but they charge very slowly.

I think I have only ever used the CAL button on my old D1 batteries before I converted them to Lions.

Robert , While re-reading the D3X manual I came across this ( exerpt D3X manual page 22 ) I suphose this counts for all D3 series. • Do not use with travel converters or adapters designed to convert from one voltage to another or with DC-to-AC inverters. Failure to observe this precaution could damage the product or cause overheating or fire. This is all GeoffR`s fault, after the " Stern Look " he gave me about checking the camera manual

Mmmm interesting, but makes sense... I guess by 'Travel Converters' they mean voltage adjusting converters rather than plug pin adaptors. As far as I know all Nikon chargers are multi voltage self adjusting, you can use them at any voltage from 100V to 240V and at 50 or 60 Hz, you don't NEED an adaptor for the voltage and if you do use one it may confuse the charger because it may loose it's reference voltage and end up either under or over charging the battery My MH-22 is dual voltage and so are my MH-21, MH-18a and MH-24 chargers. They are all self adjusting for the AC input. Which will be why the manual says, effectively, don't double adjust. Also it's possible the 'travel converter' is just a resistor which will only give the correct voltage for a given sample load, all other loads will be wrong voltage.

Robert wrote: Mmmm interesting, but makes sense...A clear case of "a little knowledge is a dangerous thing". All current Nikon chargers are multi voltage. They accept input voltages between 100V and 240V at frequencies of 50Hz or 60Hz. This range covers just about every country on earth. Voltage converters are simply transformers and shouldn't make any difference but they are completely unnecessary, why would you bother? Inverters are a different matter, the output from a cheap inverter, such as might be used in a car, isn't a very accurate sine wave and may be far from "clean". Such a "dirty" output will cause the charger to get hot and may result in internal damage. Reference voltage? Where did that come from I wonder? Chargers use voltage regulators and don't really care what the input voltage might be the regulator manages the output without reference to the input. This is after all why one uses a regulator in the first place. The chargers don't "self adjust" they are designed to produce the required output irrespective of the input, it could be 120V, 150V, 200V or anywhere in between. The device is actually a switched mode power supply and will supply the rated output even if the input changes while in use. You might also note that it says "No user serviceable parts inside". One of my MH22s had a problem which proved to be very "user serviceable" the lug to which the switch panel was attached had broken. Some epoxy putty soon restored normal operation. Generally however, leave the inside well alone.

Such a "dirty" output will cause the charger to get hot and may result in internal damage. Actually, seldom as in Never, is the sine-wave from any wallsocket " clean". Any charger could Not care two hoots about what that sine-wave looks like, as long as it is a Sine-wave...AUDIO Amplifiers would care, as the output will result in a " Gritty " sound. I could see Two problems with a Not-well constructed DC -AC converter. 1) That it delivers a wave approaching a Square-wave , which is not very likely ,but possible. 2) That the DC-AC converter is " leaking" Direct Current ( Highly Likely !! ) which Will cause Problems for Any Alternating Current appliance. To recap...AC are Pulses...DC is a steady flow , so DC into an AC appliance will Overheat said appliance , causing a Melt down, in Extreme circumstances even cause Fire...Hence Nikon`s Warning !! A Well constructed DC-AC converter is Very Expensive,as in well over a Thousand Quid .
