In principle, the case for that and went. Almost half my pocket typewriter Casio BE-300 has worked, literally, to wear. During the day she was resting (since the day getting any laptop), and in the evenings ... I do not know how she had just stood. Judge for yourself - two hours of bloody logging in solitaire, checkers, "Lines". Hour with a small continuous reading of trendy post-modernist novels (Phew). Half an hour of playing extreme music in the style of "clap-slap" (or "hip-hop - I'm not very apart). Minute and a half messing around with the dreary business applications. Yes here from anyone will carry the roof. What can we say about the rickety PDA? In short, six months later, BE-300 has become an old man impotent. Her breathing has lost its former depth. Charging the battery was reduced to a negligibly short time, but the battery life - also declined. Today it is 1 hour 40 minutes with an average brightness of the screen and at full idle computer. If the backlight set to minimum (dark as in the forest - a reflective layer behind the screen does not), while battery life increases to 2 hours 4 minutes. If this still something to start, then this short period is reduced. When you start any toy computer works for about forty minutes. For more forces is no longer ...

A computer is a pity. I'm used to it, as a mother. He's always there - in your pocket or on his desk ... now only on the table in his pocket BE-300 is not safe place, died at the most inopportune moment. There is no happiness in life ... (Damn the day when I sat behind the wheel of this vacuum cleaner!) Good news (for me) can be considered the fact that the machine warranty. MakTsentr specialists to whom I turned for help, assured that the replacement battery is dying will take no more than five minutes. I hope they do not play for me ... But the guarantee - a thing is not eternal. After twelve months from the date of purchase it will end. And I would have to (if the battery fails again) to change the power source for their money. Three hundred rubles - mere penny, but would like to do without any repairs or replacements. To in fact do, or at least delay the unpleasant moment following the replacement battery Casio BE-300, will try to compile and own and others' experience, in order to develop rules for handling the most democratic to date Pocket PC family of Windows CE 3.0.
Battery charging
Not in any way without being an expert in the field of chemical sources of electric current, I, nevertheless, I would venture to suggest that there are at least two modes of charging batteries. This charge is completely discharged battery and a partial charge. How these modes affect the durability of batteries, I do not know. In the BE-300 is installed lithium-ion battery, which, if you believe all sorts of benefits, anyway - is fully charged or only recharged. That is to charge an "empty" the battery is discharged, or a third battery, this does not spoil. True, deep discharge of the lithium battery is bad, although the BE-300 is always part of the energy reserves, cutting off at 10%-dimensional balance of the charge. On the other hand, I suspect that his fault that the battery of my cars so quickly lost the capacity. Something is wrong here ... familiar (to me) the mode of using a handheld computer - is incidental to his treatment - to replenish the address book, reading electronic texts, use the calculator, spreadsheet, keeping personal records. During the evening I five or six times (if not more) take the clipper in the hands ... And then what? And then return it to the "bed" where there is an automatic recharge the internal battery. The reason for this mess with the CCP does not want to spoil the computer specifically (and hopefully not in the manifestations of chronic idiocy). This is an elementary psychology. Machine is on the table in the "crib." And the "cradle" it is perceived primarily as a convenient stand, and not the charger. It's so natural - picked up the car, then set in place ... look at the directory (or at least in the original instructions).The lithium battery must be at least 2 years of age and able to withstand 500 cycles of charge / discharge cycles ... What? Full or partial? Or lithium battery is a damn, most importantly - a charge? Then it turns out that for the three months I was almost completely exhausted the battery life of 500 cycles? A typewriter, mother dear, for five months with a tail! Hence, a rule first - more careful with the battery. Having worked with computers for a short time, do not put it on charging, let off steam. "Crib" and you can use as a base (or, if there is a need to synchronize with a large computer), if you disable it from the power supply. Situation where at the end of the day rushing to the edge of the world, capturing almost a dead machine, is rare. Yes, and how much that will recharge the odds, if with a fully charged new (!) Battery computer "breathes" only about four hours? Let us turn to the experience of fellow "behovodov. In a conference devoted to problems of energy supply Casio BE-300, I read the recommendation is not messing with the computer too hot and too cold. In the cold lithium battery sits down immediately and is not a fact that reversible. Minus ten degrees can make a battery invalid, and minus twenty "shoot" guarantee. My computer battery is the dramatic loss of capacity during the hottest days of summer. True, I did not take a computer with you wherever you may be, simply because not left the house. But, plagued by erratic charging, the battery could not sustain, and 28-degree heat ... I'm in his place would not stand. In very warm weather (this is again a recommendation from the "Conference") the computer should not be kept in the inside pocket, where he was, in addition to temperature effects, being more hard tests and high humidity. Technology gentle and brutal treatment does not forgive ...
Additional sources of supply
I myself have an external power supply for cell replacement has not yet enjoyed and, frankly, not particularly rvus. Here again you can refer to someone else's experience. External power supply (Power Pack until the firm put aside) is a plastic container for the four elements of size AA or AAA, connected to an external power jack on the computer. The energy of the external unit does not come to power computer circuits, but only to recharge the battery. That is, there is a continuous cycle of recharging the battery, which slows down the rate of depletion of the internal battery.

Two nasty and yet I understood the moment. The first - fitted in the scheme of the battery power supply fuse (it is necessary to establish mandatory) happens to burn out. Hence, the charge current exceeds 500 milliamps, which for the PDA, and a lot of dry cells. Second - because of an external power supply system is not working the computer, allowing the built-in battery is fully discharged without the need for the integrity of the lithium battery residual energy (referred to 10%). Why is this happening - I do not know. What is read in a user conference, and transfer. Then - while the computer with external power supply on the dry cell depends on the type of batteries. The most effective option - installing alkaline (alkaline) elements, the most expensive and energy intensive. Battery life in this case doubled and amounts to about 8 hours. Depleted items after use can only throw (RUR 60, and then all the 100 - if you buy good batteries). Application of the most capacious nickel-metal hydride batteries (Ni-MH) AA size 1600 mAh capacity for increased battery life for 2,5-3 hours. Not so much, but profitable, because the batteries can be recharged repeatedly ... As for me personally, then familiarized with the experimental results more experienced than I am a sinner, the owners of the BE-300, I decided not to experiment with batteries in general, but wait until the battery brand Power Supply Power Pack.Sooner or later, but the curve track on my computer it displays. And I will be happy if ...
Science discharged
No, it's not about some special training detente. Speech - normal operation with the CPC. Can be regarded as a business and thus, is not it? Runtime PDA depends on two factors - the degree of processor utilization and the brightness of the screen. Than "heavy" will run on the machine application, the brighter the lamp will be lit backlight, the more time will be less. And vice versa - than the "lighter" application, and dim the screen, the time will be longer. In addition to the complex graphics for games (on the BE-300 relatively few), most of all machine loads the playback of audio and video. Look at a tiny PDA screen movies - it's an amateur, but the MP3 music we listen to often. (Although, if the vision is good and the memory capacity allows, why not indulge a handheld video?) If you turn off the screen backlight at all (looks like off the display itself), and full-time player audio files Casio BE-300 permits this time computer as an audio player will be about the same as that of the standalone player based on flash memory - up to 4 hours. The danger here is that, after hearing a few tracks, we turned off the machine, and then, after a couple of hours, turn it, in order to read a book or something written. We look forward to an hour or two functioning computer. And he was forty minutes off himself - because of battery discharge. Only one solution - to use the programs from monitoring the battery, which show with reasonable accuracy the energy balance and the estimated time of your computer ... But where to find these applets? Those that I come across, enthusiasm is not aroused. Miserable, uninformative, and yes even paid ... (From the site be300.ru can recommend a free program RezMeter - HPC.ru) backlit display - with its constant muting in the name of saving battery power - things are really bad. If the display backlight on or at least a quarter, to work quite uncomfortable. Well, maybe in total darkness. But the most striking level too quickly drain the battery. The point here is still in the application of the protective stickers on the screen, which reduces the brightness of the thirty percent ... Conclusion - the search for high quality labels. And do not zloupotrelyat illumination. Under the sun computer useless, so it is better not to include. In the shadows of the bedroom, or wagon coupe will suffice most of dim lights ... And do not forget that screen PDA has two adjustable parameters - brightness and contrast. Contrast can be found by selecting the optimal combination for any level of brightness of the screen lights ... If, I repeat, you have normal vision. For me, as for the old mole, these recommendations are useless. Late drink Borjomi when ... Well, you know.
My grief is light
Tomorrow I go in MakTsentr ... Povyazhu "Kase" mourning ribbon. And carried in a box - as in a small cardboard coffin ... My poor "Kasia! My rabbit nedorezanny! And why do not you lived in a spacious, comfortable pocket? Once we replace the battery, we will shine a thrush! It was not just a machine. This is - the favorite machine of one elderly gentleman .... Similarly, I say. And all the glorious tribe behovodov "I can advise about trifles not to worry. Casio BE-300 - one of the hits of the Russian computer market. Consequently, change the battery in it does not make much effort. Ten dollars - and the problem is solved. Replace the batteries at least once a year. Perhaps not razzorimsya ... The authors, translation:
