• At present, we used batteries can be divided into three categories, they are: ordinary batteries, dry batteries and maintenance-free battery three kinds of charge.
    1. Ordinary batteries; ordinaryxps m1730 battery plates are made of lead and lead by the oxide, electrolyte is sulfuric acid aqueous solution. Its main advantage is that voltage stability, the price is cheap; disadvantage is that the specific energy is low (ie energy per kilogram of battery storage), life is very short and frequent routine maintenance.
    2. Dry-charged battery: the full name is dry charged lead-acid xps m1330 battery, and its main features is the negative plates have a higher capacity rechargeable batteries in a fully dry state, and can be obtained within two years to save power, use the , simply by adding electrolyte, etc. it only can be used over 20-30 minutes.
    3. Maintenance-free battery for Nikon EN-EL8: maintenance-free batteries ,due to its structural advantages, the consumption of electrolyte is very small, basically it do not need to add distilled water in the life time . It also has earthquake resistance, high temperature, small size, a small self-discharge characteristics. Ordinary battery life is generally twice as high. there are two kinds Maintenance-free batteries on the market: the first one is a one-time increase in the electrolyte after the time of purchase does not require the use of maintenance (add additional liquid); the other is theFujifilm NP-95 battery itself, the factory has already added a good electrolyte and sealed, and Users simply can not add additional liquid.
  • The structure of battery

    • Battery lead-acid xps m1530 battery in general is made of a positive and negative plates, bulkheads, shell, electrolyte and wiring trailer coupling etc. and the discharge of chemical reactions depend on positive plate active material (lead dioxide and lead) and the negative plate active substances ( sponge-like pure lead) under the role of electrolyte (dilute sulfuric acid solution) , in which the gate plate frame, the traditional lead-antimony is made of alloy battery, maintenance-free batteries ,Fujifilm NP-120 are manufactured using lead-calcium alloy, the former used the antimony, while the latter used Calcium, it is the fundamental difference between the two points.
