Lead Acid Batteries
|
Car batteries will
not last as long as Deep Cycle batteries. They are made for high current
used for a short time when starting an engine. RV/Marine batteries are a
little better than car batteries but not as good as golf car batteries. Deep
discharges will shorten battery life. For best battery life, use shallow
discharges of 20% or less and routinely stay above 50%. Comparing depth of
discharge to cycle life of a battery routinely discharged 80%, a battery
discharged only 50% would have about double the cycle life and discharged
20% about triple the cycle life. |
|
Sealed, Maintenance-Free
Deep cycle with low self-discharge rates, low maintenance,
better efficiency, better low temperature performance, can be mounted in almost
any position and no explosive/corrosive fumes when used properly. Use a PWM
controller with temperature compensation battery sensor for accurate charging.
No equalize charging. Over charging these can ruin them from loss of water.

Golf Cart
6 volt, 220 amp hours
These electric vehicle batteries are a good first battery to
learn on. They are mass produced so they have the lowest cost per amp hour. Life
is about 4-8 years if not abused. They are 6 volt, so two are connected in
series (positive of first battery to negative of second battery) to provide 12
volts and 4 are connected in series for 24 volts; 6 are series connected for 36
volts and 8 are series connected for 48 volts. Each battery is 220 amp hours
(AH). Batteries (or battery sets) connected in parallel keep voltage the same but add the amp
hours thus increasing storage capacity. Two 12 volt sets connected in parallel (4
batteries) would have 440 AH and three sets would have 660 AH. 10.25 x7 x10.25 high, 66 lbs. You may be
able to find these locally for about $60 to $80 each.

Industrial Batteries
These high quality batteries can last 10-20 years with proper
care. Higher initial cost but may cost less in the long run. Taller cells use
less floor space, fewer cells means less caps to open for inspection and
watering. Increased liquid reserve means less maintenance. Designed to offer up
to a 20 year lifetime, 3000 plus cycles to 50% depth of discharge, 2000+ cycles
to 80% depth of discharge. AmpHours listed are for 20 hour rate. The 100 hour
rate is about 40% more AmpHours.
Surrette/Rolls batteries have a durable
double container construction (except 2 volt Single cell) for a cleaner battery.
Individual cells can be unbolted allowing for a lighter handling of battery.
Each cell is assembled in its
owner inner container made of high temperature retardant, durable polypropylene
with the inner cover heat bonded to the container, (thus acid leakage is
eliminated). The outer container is high density tough polyethylene with a
removable lid. Even if the outer container were to break the battery would still
be operable without the harmful affects of sulfuric acid spills.
Warranty is 3 years full, 7 years pro-rated. Specify WET or DRY
Shipping discount for more than 1000 pounds east of the Mississippi or 2000

Convert 115 volts AC power from the utility
grid or from engine generator into low voltage DC power. It is desirable to have
backup way of charging when batteries are low and little power is coming from
your solar modules or wind generator. Using a high amperage charger will
minimize engine generator run time, saving fuel and maintenance. Standard
battery chargers and modified square wave inverter/battery chargers will have
reduced output when powered from low cost engine generators. This is due to
generator voltage, wave shape and watts available at 115 volts. Some generators
only have half there wattage available at each 115 volt outlet. Sinewave
inverter/chargers will work better with generators. |
IOTA
DC Charger/Power
Supply
This compact, powerful charger uses a high frequency
electronic design for superior performance over regular chargers. This is more
efficient and will delivers more amps when input voltage drops. The clean low ripple
DC output can also power loads without a battery connected. Has DC output
terminals, no meter. Input: 96-140 volts AC, 47-63 Hz. 80% efficiency. Add a DC
breaker and DC ammeter on output. 2 year factory warranty.

Battery Exhaust Fan & Damper
Battery boxes should be vented to the outside for hydrogen
gas removal. This unit stops cold back drafts and provides positive hydrogen gas
venting. Use one unit per 2200 amp hours of battery with up to 125 amps
charging. Use 1.5 or 2 or 3" pipe depending on air volume needed (3-6 cfm). A
voltage sensing controller is required to cycle the fan. The voltage sensing
relays in Trace SW inverters or a voltage controlled switch may be used. 3.5x
