RECHARGEABLE POWERTECH SB2212 Deep Cycle Battery 12.8V 18Ah Lithium SB2212
Original price was: $179.00.$75.00Current price is: $75.00.
This unit came to us sealed (case unopened) and as is in the images.
We charged it to 14.60v
Discharged it to our set cutoff 10.5v @ 2A it ran for 11.15Hrs and delivered 22.507Ah 290.3Wh as per the images of our testing.
N.B. Cut off voltage is 9.2v. Unit is now @11.2v ready for shipping and will need charging prior to use………….
The next generation of power storage is here! These LiFePO4 batteries weigh less than half of their Lead Acid counterparts. They may look fairly similar to lead acid batteries, but internally they’re a totally different, next generation concept. They’re actually made up of regular 32650 LiFePO4 cells, which are in mass production for many portable devices. An internal battery management system (BMS) ensures all cells are uniformly charged and discharged, as well as providing short circuit, over current, and reverse polarity protection. This provides you with a higher degree of protection than a traditional lead acid battery which is unprotected, and can discharge rapidly under short circuit conditions, causing fire and damage. The internal BMS will also limit discharge and manage cut-off voltage, to further protect the internal cells.
This 18Ah model can provide continuous current up to 18A. Absolutely perfect for high capacity portable power, and replacement of similar capacity lead acid / AGM battery.

Description
We do our best to sort out any swollen bad packs so it is likely that most of these cells will take a charge and cycle just fine. Our shipping calculator is designed to take into consideration weight and carton size with a max weight of 25Kg, however due to size and shape of the power packs the max number of packs is limited by weight, all this has been added into our NEW calculater and New shipping contracts negotiated to give you the best possible Shipping price to your destination.
We do everything we can to supply you what you ask for but we cant see inside the power packs so you may end up with an odd mis-match keep them to one side and we’ll fix it up with your next order. However nearly every time the cell is the same value just a different Brand mostly all grade “A”cells.
Manufacturers Data Sheets provide an excellent insight into the cells design capabilities and parameters and Google is a great tool to find them. Just look for the cell data on the cell wrapping and search accordingly. The images display an example of what the the power packs look like
The health of a battery is based on three fundamental attributes:
Capacity, the ability to store energy. Capacity is the leading health indicator of a battery Internal resistance, the ability to deliver current Self-discharge, indicator of the mechanical integrity When making these measurements you must consider type and accuracy of equipment used, as well as ambient and battery temperature. Our combined cell count over our range of products goes well beyond 76k refurbished cells. Free Local pickup is available. We will also combine postage with other items so as to reduce shipping costs. Due to the nature of our Lithium products we offer no guarantees as to their use by the end users skill set and do not warrant there end use in any way. We have loads of unlisted stock so if you need cells you dont see just ask!
