Contraindications:
- Significantly thicker and wider than usual and therefore may not function anywhere, see Comparison of Dimensions
- Only thin shrink film around the envelope around under the cover lying, tactile grid construction and therefore mechanically more fragile
- No imprint of the polarity on the envelope
Because they actually have about half the capacity compared to the currently most powerful 7.2V Li-Ion batteries, but this advantage usually can not play a much too low voltage -
Dimensions:
Tensai: 47.5mm x 26.5mm x 17.6mm approx
older NiMH Ansmann 8.4V: about 48mm x 26mm x 15,3mm
Ultralife 9V lithium battery: approx 47.5mm x 25.5mm x 16.5mm
It is difficult to assign full 5 points in this negative list, but for 9V batteries we are interested more, if you have specific problems and I currently know of no better compromise. Here is why the applications:
Charger:
+ Fully up to the specified voltage loaded in the old Energy4 from Ansmann
+ Fully up to the specified voltage loaded in the modern CM 2016 by Voltcraft
+ Fully up to the specified voltage can be loaded at the onsite 4-loader Tensai TI-NI9.6V plug quick charger for 1-4 9V 6LR61 6F22 9V battery (8.4V / 9.6V), trickle charge, individual supervision
+ All chargers are protected against polarity reversal - a lack of imprint is therefore irrelevant
Juiced Link Riggy Micro RM333:
A microphone pre-amplifier, which provides a voltage converter for 48V phantom-powered condenser microphones and with me ensures directly on a Canon 5D Mark III to deliver clean sound. With phantom power is relatively energy-hungry, otherwise rather frugal, but precisely because of the phantom power you buy something so - so far quite simply hungry.
Pro:
+ Compartment is big enough for the battery
+ The term is absolutely practicable
+ The connection polarity is mechanically coded, a lack of print thus not relevant
+ Camera technology is notoriously sensitive - one is so accustomed to treat things with care and therefore less capacity would be a much larger deficit than the lack of a stable metal casing
Although the RM333 has a switch to adjust etc. The battery indicator on Li-ion typical voltages of only 7.2 V - according to experience (CR3V as Li-ion variant in old Olympus E-20P) the cells then life due to high stress, and deep discharge to primitive chargers but not for long and provide for their cell typically too low voltage also not nearly as long as energy, as one would expect due to the typically up to twice the capacity. For the E-20P, I now also AA batteries in modern NiMH technology with charge conservation (Sanyo Eneloop) - technology that has been there so far proved much better than anything else.
OTS Buddy Phone:
A kind of ultrasound-based, wireless radio intercom for divers.
Pro:
+ Compartment is big enough for the very thick battery
+ The term is absolutely practicable
Contraindications:
- The fragile shell should never roll around without protective battery box in dive gear
- No imprint of the polarity on the envelope
Again, as previously was ultimately the decisive power. But here is also the missing print a shortcoming. Would it not be seen and not so easy, with a permanent marker to write on the basis of the icon image in the battery compartment with a stylized form of the connections without doubt the polarity on the cells, which would now cost a smooth point deduction. The same applies in this particular case for the more sensitive shell, but who throws batteries in a battery box, but simply somewhere between salt water soaked dive gear, which is hard to help with cases still stable.
Other Uses:
Thanks longer charge retention and sufficiently high voltage reserves and use in smoke detectors and in multimeter (Universal measuring device for voltage, current and resistance) seems reasonable, but can be tested much later thanks to fresh, long-life lithium batteries.
Conclusion:
Mechanically, the battery is probably not anywhere. Either he's simply got too thick and does not fit, or his thin foil envelope is too sensitive for a hard life. Unfortunately, the otherwise rather spartan with refreshing Tensai NiMH 9.6V 270mAh and because more typically 10.6 V also a bit misleading printed envelope is absent also not entirely uninteresting indication of where now are positive and negative poles, but often the connection preventing reversed polarity thanks to solutions not relevant and can be remedied quickly by permanent marker, thanks to a lack of colorful advertising, unnecessary warnings etc.. Who needs power, or indeed longer conservation of charge, is should definitely look at the but. Arg large the selection of alternatives is not currently and comparable batteries tend to be also significantly more expensive - if you find ever since.
The voltage is about 10.6 V for charged batteries (measured a few days after the charge) is still in fresh batteries more typical context and should not be too high and even in return for a noticeably better use for most applications the capacity care. In total discharge but be sure and do not overdo it up here. The store is also no problem, because modern handlers look more to a drop in the charging curve, rather than the actual voltage and is obviously still well under typical chargers. Since only very tiny single cells are charged, one considerably more patience than the AA batteries has to apply here, however. Although higher charging currents appear realistic, but do not do the cells necessarily good.
Conceivable and possibly desirable course would also Li-ion battery with three cells. The typical 7.2V with only two cells are available for most applications in any case just a bit poor. To what extent would then freshly charged overwhelm the surge tolerances of various circuits to be seen, but it would then be up only three rather than as in this case, presumably 8 series-connected cells needed (battery packs have notoriously problems - the more batteries, the greater the anger) and potentially even higher capacities would be feasible. But one would have, however, re-use special loader then tend again harm the batteries, because their electronics unlike modern universal chargers often is very primitive, and whether it is really worth to be seen. Currently, at least that is the state of the art and within the limits described quite practical.
