This type of VRLA battery gelatinizes the electrolyte with SiO2 (silicon dioxide) to stabilize it. While renowned for their exceptional duty cycle life, they are rarely used in campers due to cost, limited charging max similar to flooded((C/5, https://www.trojanbattery.com/pdf/datasheets/Motive_T1275-AGM_DS.pdf and https://www.qsl.net/wb3gck/gel-cell.htm)), and sensitivity to overvoltage. | This type of VRLA battery gelatinizes the electrolyte with SiO2 (silicon dioxide) to stabilize it.

"Lead crystal" batteries may actually be gel, since they claim the electrolyte is made of SiO2.((http://azimuthsolar.ca/getting-silicon-dioxide-sio2-batteries-charging-instructions/)),((https://www.solarpaneltalk.com/forum/solar/the-pros-and-cons-of-solar-energy/22713-why-are-there-no-lead-crystal-battery-distributors-in-the-usa-or-canada?p=272482#post272482)) | === lead crystal === |

| These appear to be an AGM variant with some gel: |

| >> The plate group was taken apart, which showed that the separator is a standard AGM (absorbent glass mat) with double layer. Additionally, a very small amount of gellified electrolyte was found on top of the plates. -- - [[https://www.dropbox.com/s/zz7vf6k8y36btfq/Memo%20%28internal%29%20Betta%20Lead%20Crystal%2026032013.pdf?dl=0|leaked pdf describing a Betta battery teardown]] |

| The "Lead crystal" name appears to refer to the gel component, since manufacturers typical claim the electrolyte is made of SiO2.((http://azimuthsolar.ca/getting-silicon-dioxide-sio2-batteries-charging-instructions/)),((https://www.solarpaneltalk.com/forum/solar/the-pros-and-cons-of-solar-energy/22713-why-are-there-no-lead-crystal-battery-distributors-in-the-usa-or-canada?p=272482#post272482)) |
