EVDL Dave R., Comparing on a weight basis $/lb (on the theory that weigh goes with Pb content which goes with quality of design and manufacture and looking at $/ Ah:
*#1 13lb* $3.46/lb @ $45 17.2 Ah *$2.62/Ah* http://www.atbatt.com/genesis-np18-12-12v-172ah-sealed-lead-acid-battery-with-nb-terminal.asp?cr_brand=BB&cr_product=BP17-12#specifications *Is this the "Hawker Genesis" you were talking about?* *#2 14lb* $3.57/lb @ $50 21.6Ah *$2.31/Ah* this one weighs an additional pound for $5 more: http://www.atbatt.com/power-sonic-psh-12180nb-fr-sealed-lead-acid- battery.asp?cr_brand=BB&cr_product=BP17-12 *#3 14.1lb* $4.15/lb @ $58.5 22Ah *$2.63/Ah* http://www.atbatt.com/amstron-12v-22ah-electric-vehicle-agm-battery-nb-terminal.asp?cr_brand=BB&cr_product=BP17-12#specifications *#4 14.4lb* $4.38/lb @ $63 18Ah *$3.50/Ah* http://www.atbatt.com/bb-bp18-12-12v-18ah-agm-battery-w-nb-terminal.asp?cr_brand=BB&cr_product=BP17-12#specifications *#5 14.5lb* $4.96/lb @ $72 20Ah *$3.60/Ah* http://www.atbatt.com/bb-battery-hr22-12-sla-battery.asp?cr_brand=BB&cr_product=BP17-12 *#6 15lb *$6.60/lb @ $100 20Ah* $5.00/Ah* http://www.atbatt.com/bb-evp20-12-12v-20ah-agm-battery-w-nb-terminal.asp?cr_brand=BB&cr_product=BP17-12 Raises all sorts of questions... Is #3 lying about the Ah? Does the low weigh really me it is not as good as say #5 which weighs a 180 grams more for an additional $14 each? On a pure money for performance basis one of the lowest weigh, least expensive #2 seems like a good deal. Can 21.6Ah be believed? Is there any merit at all to buying #6? Its price point looks terrible, but on the weight theory is is best. This is a great way for me to learn here, if you all are willing to chime in...
