Lead acid manufacturers (including Discover) have conditioned you to look at “Temperature vs. Cycle
Life” or “Cycle Life vs. Depth of Discharge (DOD)” graphs to indicate expected life or, more
accurately, their remaining time to failure, and to overlook the “big elephant in the room”, which
is that lead acid batteries start to lose their original capacity nearly the moment they are put
into service and that the total available capacity in cycle 500 will be much less than the total
available capacity in cycle 10.
The industry aggressively contends that “life cycles” are the measure of a batteries quality versus
the competition and its suitableness for energy storage use. A successful high quality lead acid
battery bank will maintain its ability to deliver its original published capacity for 500 cycles
(less than 18 months of daily cycling) only if the batteries are kept cool, not deeply discharged,
recharged completely every cycle and watered regularly (flooded cells). In the real world, cycle
counting is neither verifiable nor reflective of the real function of a battery bank, which is,
Discover AES LiFePO4 batteries with AEON cycle life technology can be continuously
operated in a partial State of Charge (SOC), or alternatively discharged and charged to 100% of its
rated capacity without consequence. Discover AES LiFePO4 batteries will provide > 90%
of original energy storage capacity for a minimum of 10x that of a high-quality lead acid bank.
Discover AES Battery Warranty
Discover AES LiFePO4 batteries are warranted by a 10-year, unlimited cycle, 38 MWh total
energy throughput warranty providing confidence that Discover’s batteries will provide your
customers with the long-term, reliable energy storage they are paying for.
Take it from a company that has been designing, manufacturing, distributing and installing lead acid
batteries since 1949: You can’t afford lead.
Discover AES Battery Features
Discover AES LiFePO4 batteries will significantly outlast lead acid batteries, and dramatically
reduce energy storage costs over the life of the system.
Scalable energy storage to meet the run-time and autonomy requirements unique to off-grid solar and
whole home backup power.
Discover’s LYNK enables remote reporting of system level status through existing web portal and cloud
monitoring services. Plug-and-play, closed loop communications provides adaptive, real- time
interaction between the Discover AES LiFePO4 battery and connected power electronics.
