Comparison Motorola DP4800E vs Motorola DP4600E

The capacity of the radio battery, in other words, the amount of energy that the battery can store. It is standardly measured in ampere-hours: 1 Ah means that the battery, when fully charged, is capable of delivering a current of 1 A for 1 hour. In portable electronics, measurements are typically made in a thousandth of a milliamp hour (mAh).

In general, the higher the battery capacity, the longer the radio is able to work; however, this is true only under otherwise equal conditions. In fact, due to differences in the specs of individual models (range, transmitter power, etc.), their power consumption can also vary significantly, and even situations when a model with a smaller battery capacity of two walkie-talkies will have greater battery life can happen. This is especially noticeable when comparing compact models of "urban" ranges and powerful "long-range" radios that require a lot of energy. Therefore, for walkie-talkies, the battery capacity itself is rather an auxiliary parameter — the operating time in different modes provided by this battery is of decisive importance (see below).

The maximum operating time of the radio in talk mode — i.e. with continuous radio traffic and approximately equal distribution of time between work for reception and transmission. You should pay special attention to this parameter if you plan to communicate intensively. Note that when receiving, much less energy is consumed than when transmitting. And therefore, in fact, the time in the talk mode, even with continuous radio exchange, may differ from the claimed one both downward (with large volumes of transmissions) and upward (when working mainly for reception).

The walkie-talkie has a case that allows the device to endure more severe shocks and drops without consequences than models with a conventional case can withstand. You should pay attention to this feature if you plan to use the radio in adverse conditions where there is a corresponding risk — for example, in camping trips, construction, military affairs, etc. Such models have the American military MIL-STD-810 standard. It imposes quite stringent requirements on the test subjects: the level of product resistance to impacts during drops and shakes is checked, vibration tests are carried out, the device is tested in a wide temperature range, in rain, in fog, under the influence of sand, dust, etc. However, the MIL-STD-810 label in "civilian" products does not always mean the highest degree of protection. This is due to the lack of strict regulation of the tests. So, the most ingenious vendors test the gadgets literally on one or two points of the programme from an extensive list and often deliberately do not cover which tests were passed. Accordingly, the specific features of such protection remain reliably unknown. The standard has been live since 1962. Each new version of it is indicated by a letter of the Latin alphabet at the end. The further the letter down the alphabet, the more recent the version of the certificate. Since 2008, the MIL-STD-810G specification has been live everywhere, and in 2019 a new edition of the MIL-STD-810H standard w...as approved.
