My next set will be SiO2. They can withstand 620 cycles to stone bone dead. Self discharge rate is 1.6% per month.
Don ... yeah, I kindof agree ... if:
1. They were available in Group 31 size instead of Group 27 size,
and
2. They could be charged directly by any good old run-of-the-mill engine alternator without burning up the alternator,
and
3. They could be charged if you wanted to and without damaging them or the converter by any good old run-of-the-mill 13.8 volt converter that used to come in many RVs.
IAW ... if certain SiO2 batteries were finally true 12V DROP-IN REPLACEMENTS for 12V deep cycle AGM batteries (the AGM batteries that charge good enough from a stock fixed voltage converter and don't ruin stock alternators) ... then I might consider the SiO2 batteries, eventually.
IMHO ... I feel that Battle Born batteries aren't quite there yet unless you have plenty of $$$$ to spend AFTER spending the $$$$ for the BB batteries themselves. :S
