Which battery would be suitable for UPS in hot area?

[signode]

Hi;

I want to select a battery 12V-70AH for a UPS (Un-interruptible Power Supply) but problem is “temperature”. The environment temperature where UPS would be installed can be raised up to 42C. So the flooded lead acid batteries can not work there as each 8C of temperature rise decreases the life of lead acid battery by half. Can anyone suggest me then which battery should be selected?

“Lithium-ion cells are rechargeable and deliver a voltage of 3.7V, have no memory effect, operating temperature range from -20ºC to +60ºC. Nickel-cadmium batteries have a legendary reputation for robustness, reliability and service life. This is the benchmark technology for difficult and demanding applications: operating temperatures from –40ºC to +60ºC, excellent cycling capability, long storage life, and low or zero maintenance.”

Here’s an excellent overview of probably the best choice:

“Durathon Sodium-nickel-chloride battery technology is suitable to operate in extreme ambient temperatures without adversely affecting energy delivery, life cycle and safety.
Durathon Batteries do not require the use of air conditioning or heating and are capable of operating at temperatures ranging from -40°C to 65°C.
The Durathon Battery’s chemistry does not develop significant vapor pressure until the cell temperature reaches a level 450°C (842°F) above the nominal battery operating temperature. This gives the Durathon Battery significant thermal margin to avoid high pressures within the cells.”

Just curious. Are you using a these (lead-acid?) batteries in a series arraignment to get, say, a 120vdc or 240vcd source? The trade-off of battery cost vs. cost of environmental control may need to be considered.
