"AGM Car" batteries for less used tractors?

[sixdogs]

I am getting over 10 years on AGM batteries in tractors, up to 15 years at the most. I do pull them in the off season and bench them on a maintainer.

I don't pull my batteries but keep fully charged a leave on a 1 amp trickle charger quite a bit. I use the NOCO 1 amp smart charger for $30 on Amazon. After doing that I noted my batteries were lasting far longer.

I have 3 of the NOCO chargers (two 2 amp and one 5 amp) and one Optima charger that I rotate around. Amazing how long the batteries are lasting.

Good point. I wanted to start a thread that everyone with equipment should own at least several of the $30, one amp NOCO smart chargers. You don't have to leave them on all year around but I do rotate over winter and do put on first thing in the spring for several days. I also have a 3 and five amp charger.

I posted before but I have had many batteries well over 10 years old. These smart chargers pay for themselves.

I have 2 Opimate chargers (which I think are the best smart chargers), and at least 10 of cheaper smart chargers, 1 LifePo1 chargers for lithium batteries, one 60A booster (old style, not smart) and one 200A booster (old style not smart).

Experience tells me that a guy needs at least one old style booster charger to charge up batteries that are will work, but are discharged because smart chargers cannot charge a discharged battery.

Minnesota that is one way to handle it and it works if you don’t forget it and leave it on all week. I have been told that you can take a nine volt battery and tie it in and trick the smart charger into doing its job. I usually put a set of jumper cables in with the little smart charger. Now I have never tried these chargers you like, but if they are good as a no co they are something else. Have a good weekend sir

I thought there was some way to override a smart charger to get it to charge a battery that was fully discharged. I'm sure I read this somewhere but not sure where.

Look up "force" mode in the instructions.
For the NOCO Genius 1,the complete manual is online.
Too bad not in the box!

I have a 1/2" Milwaukee impact driver that if I forget about leaving a M18 battery on it, it'll flatline the battery and then none of the Milwaukee chargers will charge it up. So I use two razer blades to jump two M18 batteries together to boost the flat battery up to enough for the charger to recognize the battery, or I use the blades with a bench top power generator to do the same.
Bench voltage generators are a godsend for doing bench testing of vehicle junk. Here I'm playing with some whip lights.

I really do not RFM much because I'll forget what it said, anyway.

The trick that I have heard is to parallel a good battery with the dead battery with a set of jumper cables, then connect the smart charger. The good battery will keep the voltage high enough that the smart charger activates. I would take the good battery off as soon as the dead battery has a charge to it so the charger can focus on that battery.
