Preferably, the acid adding hole 122 is located in the middle position of the two pole holes 121; a porous net bag 123 is provided on the side of the cover body 12 close to the battery body 20, and the net bag 123 is arranged corresponding to the acid adding hole 122, and a porous fiber cotton 124 is arranged in the net bag 123, and an extension tube 125 is formed on the side of the cover body 12 away from the battery body 20, and a safety valve 30 is sealed inside the extension tube 125.
[0031] The horizontal storage battery provided in the present application realizes the addition of acidic substances through the acid adding hole in the middle of the cover body 12, wherein a porous fiber cotton 124 is arranged in the net bag 123, and the porous fiber cotton 124 is taken out when adding acid, and is put in when the battery is horizontally placed to prevent leakage of acidic substances. There are a large number of gas channels inside the porous fiber cotton 124, and the cylindrical porous fiber cotton 124 can isolate the material in the battery from flowing out and block the rubber safety valve 30 of the safety valve seat. This structure effectively solves the technical problem in the prior art that the battery is damaged due to leakage of acidic substances when it is horizontally placed.
[0032] Preferably, the net bag 123 is a fiber cotton net bag.
[0033] In order to ensure a smooth acid addition process, a plurality of acid flow holes are formed on the bottom and sides of the net bag 123 .
[0034] The battery body 20 includes a positive electrode plate 21, a negative electrode plate 22, a separator 23, a positive bus bar 24, a negative bus bar 25, a positive electrode column 26 and a negative electrode column 27;

[0036] When the acid material is added into the housing 10 , most of the areas of the positive electrode plate 21 , the negative electrode plate 22 , and the separator 23 away from the cover 12 are covered by the acid material, forming an internal circuit of the battery.
[0037] The battery body also includes a pole fixing ring 28 and a sealing ring 29. The pole hole 121 has a receiving groove 1211 extending inwardly. The bottom of the receiving groove 1211 is formed with an annular limiting edge 1212. The side wall of the receiving groove 1211 is formed with an internal thread.
