Valence Lithium Battery U1-12RJ with Ethernet Cable | 12V 40AH (various tested capacities)

Ships to contiguous 48 states. Drop in replacement for lead acid battery. We only guarantee these packs to capacity test at their individually tested amp hour rating. A packs ability (or lack thereof) to hold a full charge is a reasonable indicator of it's remaining lifespan. Because of this lifespan consideration the packs are priced on a curve instead of a set amount per Ah capacity. Item sent could have grey,black, or blue top versions as pictured, just depends on current stock. IMPORTANT - PLEASE READ:These packs self drain slowly due to the internal BMS and LED indicator.If these packs sit for too long or are discharged too low they will go into a safety mode that requires them to be trickle charged before they can be used again.  Specifications U1-12RJ Voltage12.8 VNominal Capacity (C/5, 23°C)40 AhWeight (approximate) kg6.5 kgWeight (approximate) Ibs14.3 IbsDimension incl.
