Operation batteries used on board the ship are very different from the conditions of any other batteries. First, they operate under constant rocking, at times very strong. Second, for marine batteries are more likely contact with water. And thirdly, many vessels do not operate in winter, and hence the battery can be recharged. These special conditions make on-board batteries are special requirements. Not surprisingly, the use of on-board batteries not intended for this purpose, such as automotive, inevitably accompanied by more or less serious problems. The most common complaint in this case – a very short battery life and associated costs for their frequent replacement. High-quality marine battery is rated for four years, while Many cheap its brethren need to be replaced once a year and a half or even annually.
Rough estimate of marine life battery can be claimed on the number of charge / discharge cycles. Please note that many Manufacturers are cunning, indicating the number of cycles when tested in standard conditions, and it is overpriced. Another common problem of substandard batteries – it's too fast to self-discharge. There can be several. For example, savings in the production of lead plates of lead-acid batteries, or savings in production process, since it is not only the mass of the lead plates, but also their shape and location. Thin cheap housing can easily crack from leakage acid, and furthermore, contributes to the rapid self-discharge due to poor insulation. Has a value and quality of manufacture of the battery.
Construction of residential buildings using modular furniture (inlaid furniture, modular systems) is today, perhaps, that the most reasonable and cost-effective solution, because, in this case we choose not only those subjects who comes to our taste, but also those that have a specific targeted solution. Thus, filling the single room with furniture, we not only solve the issue of placement of things, but also intelligently manages the space in which, above all, we live – enjoy light and air – we, not our furniture. Widespread modular furniture was in the late 90s of last century and immediately brought chaos to the 'orderly rows' furniture trade – in general, and cabinet – in particular. "Why?" – You ask. Yes, because the usual 'Soviet' man much more of the heart was the word 'suite'! I bought a headset – and everything! The whole concept of resettlement housing amounted to only: where the 'get' and to 'cram' at the premises to which this is the headset was designed. The emergence of modular furniture in the commodity markets made people completely reconsider their views on arrangement of living space.
