This is a set of a 12V 12Ah sealed battery and charger. The EVA case is from Taka Sangyo Co., Ltd., known for its quality. The included charger indicates charging completion with a lamp color. The charger is a product that meets domestic safety standards and has PSE certification. It's a fully sealed battery, so there's no need to add liquid. You don't have to worry about liquid leakage even if it's tipped over. Ideal for powering fish finders and electric reels. The 12Ah capacity can be used for a day's fishing with small to medium-sized fish finders of about 5-7 inches. (Please consider the usage time as a guideline, as it varies depending on the usage conditions.) Battery size: 151mm x 93 x 98, 4.3kg Comes with a sturdy EVA carry bag with a bottom plate. It's very convenient for storing the battery itself and cables together. It has a double-opening zipper, so you can minimize the entry of splashes by tightening the gap between the cables connected to the battery and the bag. Product photos using a blue case are included to show how to prevent splashes from entering by tightening the zipper while the cables are connected. * We will deliver the product in a state close to full charge, but we recommend charging it after receiving it and frequent charging if there is a long period of time before use. * We cannot respond to requests for discounts. #12volt battery #battery #electric reel #power supply #long #battery charger #Daiwa
