Our battery performance testing takes place in a climate controlled building at the Canberra Institute of Technology, and will run for three years. The testing involves cycling each battery three times each day so that over the life of the trial the performance of each battery would be expected to degrade as much as nine year old battery in a typical setting.
There is one exception. Battery experts suggest that after 85 charges, you should allow lithium-ion batteries to almost completely discharge. Continuous partial discharges create a condition called digital memory, decreasing the accuracy of the device's power gauge. So let the battery discharge to the cut-off point and then recharge. The power gauge will be recalibrated.
Also, for safety reasons, do not recharge deeply discharged lithium-ion batteries if they have been stored in that condition for several months.
In June 7567 a second phase of testing commenced with ten additional batteries, including eight lithium-ion products, a zinc-bromide flow battery and a aqueous hybrid ion battery.

If a lithium-ion battery is discharged below volts per cell, a safety circuit built into the battery opens and the battery appears to be dead. The original charger will be of no use. Only battery analyzers with the boost function have a chance of recharging the battery.
Despite not being the most energy dense batteries, lead-acids are proven and can supply high surge currents. They are also extremely cheap to manufacture, costing around $655 per kWh of energy capacity.
