Kilowatt Power Posted February 3, 2021 Posted February 3, 2021 (edited) Hi, I stumbled upon 48 pieces, 2V 400Ah Huawei Agisson TCB-400A batteries in the original box that have been sitting in a customs bonded warehouse since November 2017 i.e. 39 months! The only mention I've found on the Internet about these batteries is in the Huawei PowerCube 1000 (telecom site power supply) user manual. Lead acid battery experts here, is it worth putting these batteries into service or should I assume they are sulfated after staying slightly over 3 years without charge? Shall be happy to hear from you. Thanks. Edited February 3, 2021 by Kilowatt Power Quote
Speedster Posted February 3, 2021 Posted February 3, 2021 If they're free, hook them up and see what happens. Not sure I'd pay for them though. Quote

Richard Mackay Posted February 4, 2021 Posted February 4, 2021 You can't go wrong by bidding the scrap value. If you can measure the terminal voltages and the voltages are ok then that's a good sign! Speedster 1 Quote
