Re: Optima 6V batteries production

"Good quality tenders"... give me an example, I've found a dozen, $15 to ten times that and none specify 6v AGM. Do you feel that the AGM (Optima) will tolerate a "Normal" charger? Thanks for any advice, I need it! |

Re: Optima 6V batteries production
NAPA specs show 12Volt only for that charger.

Re: Optima 6V batteries production
I have used regular cheap 6/12 battery tenders on both of my optimas. The first lasted 14 years, the second is going on 8 years and still going strong. THere are only two kinds of 6 volt electricity : AC and DC. An Optima sure isn't AC.

Re: Optima 6V batteries production
oops, that late night surfing and my mistake. I corrected the part number. The 2 amp # 90-302 , 3 amp # 90-506 , and 3 amp # 90-515 are all 6/12 volt maintainer capable that will work on an AGM battery. Solar makes a 4 amp 6/12 volt maintainer to NAPA SOR # PL2140 also Last edited by uncle buck; 01-31-2019 at 10:00 AM. |

Think battery tender has a 6v tender that is well thought of. . |

Re: Optima 6V batteries production
Wal-Mart has a 6 and 12 volt 3 amp trickle and AGM charger,around $15. Used to have Schumacher brand but is now a wal-mart house brand.Looks the same though.

Re: Optima 6V batteries production
Costco has Battery Tender brand at a good price. Every so often they have an in store rebate making them even cheaper. I only paid $27 last time. Super deal!
