Battery manufacturers provided by battery manufacturers are the theoretical values under certain conditions and cannot be equivalent to actual life. The actual service life is closely related to the conditions of use (ambient temperature, discharge depth, power failure frequency, battery management, etc.), and there is a difference in design life, and even differs far.
Domestic access network supports 12V battery development, current access network supporting 12V battery is mostly built-in to the lowermost layer of the main equipment cabinet, and daily access network maintenance sometimes ignores the check of the battery.
From the perspective of battery maintenance, the following factors need to pay attention to the battery selection:
1. Battery performance ratio is not ideal in the use environment, a remote location is relatively remote, equipment reliability (quality performance) is the primary consideration, and the price factor (within a reasonable battery performance price range);
2,2V battery selection selection according to the actual use requirements of the access network, comply with the YD / T799-2002 standard, and formulate the corresponding selection specification of the battery;
3, the main, secondary equipment bundled (integrated) Matching method due to the characteristics of dispersion construction, the engineering installation, maintenance workload, plus some equipment, in general, main, auxiliary It should be a preferred solution;
4“split into two”It is a mainstream trend that improves system power safety. For example, 48V 200A·h, use 2 groups of 48V 100A·H in parallel, than 1 group 48V 200A·H reliability is high.
