AI Customer ServiceYou should never get batteries hot enough to even think about boiling. 110F is PLENTY (dangerously) hot for them. Altitude would be a factor only for vent pressure for sealed styles of batteries. Re: High altitude affects batteries? You should never get batteries hot enough to even think about boiling. 110F is PLENTY (dangerously) hot for them.
The fire hazards of lithium-ion batteries were characterized by measuring the ignition time, mass loss, heat release rate (HRR), and total heat release (THR). From the results, the ignition time of single battery decreases with the ascending of the state of charge (SOC), whiles the mass loss, and ejection energy increase with that at two pressures.
Cell phone batteries are a different chemistry than we are talking about here with Lead Acid batteries. Altitude can have an effect--but probably from two mechanisms... One is temperature--Above ~5,000-7,000 feet, many electrical devices need power derating because there is less dense air and less cooling effect.
Solution slowly bring up the charge and bring them to a gassing sate ( boiling ) after 10 min. stop allow to cool refill the water and recharge. the same is a problem for backup and not used for a few months the capacity drops. because the battery is a sleep. greetings from Greece. Re: High altitude affects batteries?
Aricell manufactures non-rechargeable lithium-thionyl chloride batteries. A 1986 Jet Propulsion Laboratory study titled Safety Considerations of Lithium-Thionyl Chloride Cells noted that "safety hazards have ranged from mild venting of toxic materials to violent explosions and fires."
The second issue is that NiMH batteries are designed to get hot when charging (high end chargers take temperature into account during charging). The batteries may develop higher pressures during charging due to poor cooling.
