Best house battery?
Hi guys. I'm sure this discussion is somewhere on here, I can't seem to find it. Anyway my house battery has died. It was a Lifeline AGM deep cycle. These batteries are pricey and heavy! Someone t...

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
1. Actually they have a 100 amp-hour which might be a group 27, but I don't see why a group 31 would be more useful. Batteries are available in a wide range of sizes and voltages, even up to 270Ah 12V 8D batteries
2. SiO2 batteries charge similar to other lead acid chemistries – 14.4V – 14.7V boost/bulk and 13.5V – 13.8V float charge. Like lithium ion, no equalization is needed. Charging rate is C/4.
3. No problem charging from an alternator, because the alternator will see the chassis battery first--and taper accordingly.
They do not require charging to 100%.
The 100 amp-hour can have a draw rate of 900 amps.
