Which batteries are appropriate for low temperature operation?

One of the biggest threats to batteries is the temperature. It is vital to keep your batteries in conditions that do not affect their chemistry. Unfortunately, getting the right temperature is never easy. Whereas high temperatures are bad, cold temperatures are not good either. Charging a battery above freezing temperature is one of the biggest challenges for European, American and some other countries.
For low temperature operation, EverExceed offers full range of Nickel cadmium batteries and Lithium iron phosphate batteries for variety types of applications.

Nickel Cadmium Batteries
EverExceed Nickel Cadmium Batteries have been designed in such way to cover wide operating temperature range -40°C to +60°C; specially to sustain in low temperature. These batteries also can tolerate extreme of -50°C to +70°C (-58°F to +158°F) for short periods. Our NiCd batteries have injection moulded plastic grids; both separate plate and insulate plate edges. For extremely low temperatures a special high density electrolyte is used. The block battery fitted with a specially designed flame arresting flip top vent and does not produce corrosive vapours.

Benefits:

·         20+years operating life;
·         Minimal maintenance
·         No downtime
·         No replacement cost

Lithium Iron Phosphate Batteries
EverExceed Lithium Iron Phosphate Batteries can be safely discharged over a wide range of temperatures, typically from –20°C to 60°C, which makes them practical for use in all-weather conditions faced by many potentially low temperature applications. For example, at 0°C a lead-acid battery capacity is reduced by up to 20%, while a lithium iron phosphate battery suffers only a 10% loss at the same temperature. When it comes to recharging lithium-ion batteries, however, there’s one hard and fast rule: to prevent irreversible damage to the battery, don’t charge them when the temperature falls below freezing (0°C or 32°F) without reducing the charge current. Charging below 0°C at an inappropriate charge rate causes the battery to become less mechanically stable.

Benefits:

·         Higher cycle life at 100%DOD
·         Lighter weight to move flexibly
·         Mechanically stable
·         No sudden death
