Sanyo claims to have less performance loss that other brands at high temp. The downsides are that they are expensive and the warranty is 20 years, rather than 25 as with Sharp. Drake Drake Chamberlin Athens Electric OH License 44810 CO License 3773 NABCEP TM Certified PV Installer Office

Trojan T105, Deka GC15, most every battery maker including Sears sells them. They're generally a 6 volt 220 to 235 Ahr, deep cycle, 65 lb battery that has been the main stay of small off grid systems for decades. They are primarily used in golf carts, so they are readily available, and usually
