Jonathan, Thank you for asking.
Trojan Signature L16P and Trojan Signature L16H are durable deep-cycles flooded lead acid batteries with great cycles performances: 1,200 cycles @ 50% DOD, and, 3,000 cycles @ 20% DOD. Their complete cycling performances curve info is available on their respective datasheet on our website, see here: ü Trojan Signature L16P: http://www.trojanbatteryre.com/PDF/datasheets/L16P_TrojanRE_Data_Sheets.pdf ü Trojan Signature L16H: http://www.trojanbatteryre.com/PDF/datasheets/L16H_TrojanRE_Data_Sheets.pdf Sunniest regards, John John F.

Last week was a busy and I was away from my desk most of the time with limited access to Internet. Both the Premium "RE" versions L16RE-A and L16RE-B, and, the Signature L16P & L16H are great deep-cycles lead acid batteries for solar applications. The key differences between them are: The grid is thicker for the Premium "RE" L16RE-A and L16RE-B, which effectively reinforces further the frame strength which results into a greater corrosion resistance; There is relatively more electrolyte in contact with the plates in the Premium "RE" L16RE-A and L16REB, which enhances the electrochemical reaction, particularly during PSOC; The rubber-based multi-rib geometry separator is approx. 30% thicker for the Premium "RE" L16RE-A and L16RE-B, which translates into a longer life of the separator. The thicker multi-ribs geometry keeps over time the acid channels open longer, promoting the flow of the electrolyte . As a result, the thicker separator is reducing the risk of stratification and enhancing electrochemical processing throughout the plates, resulting into longer continuous performance of the battery. In the approx. same form factor (except the height), this results into more lead per Ah capacity on the L16-RE units nameplate. As a consequence, the cycling performances of the Premium "RE" is 1,600 cycles @ 50% DOD and 4,000 cycles @ 20% DOD. Respectively 1,200 cycles # 50% DOD, and, 3,000 cycles @ 20% DOD @ 20% DOD, for the L16-P & L16-H. I hope this helps. Let me know if I can shed further light on other attributes of lead acid batteries. Sunniest regards, John John F.

Could anybody explain the technical differences between the Trojan L16 and the L16RE-B's. I have read all the brochures but would like to understand what is going on in there instead of getting the marketing of DuraGrid(tm), MaxGuard® XL separator and Alpha Plus.

Premature failure is my experience. About 60% of the cycle life compared to Trojan L-16's and also Surrette/Rolls. I've been using those since 1985. Back to using Trojan. Specifically RE-B's either L-16, or T-105. And have used Trojan Industrial IND 13-6V on one system with good success with another set ordered.
