How to charge battery

[Brian Butt]

My tag battery is dead from sitting for a few months. Someone told me I can just charge it with a car battery trickel charger. Is it ok to use this type of charger? Thanks!

Yes, you should be OK using any 12 volt charger so long as you do not exceed the capacity of the battery. Exceeding the capacity of the battery will boil the battery dry and kill it in short order.

Do not be surprised if the battery is beyond saving and will need replaced. Batteries left in an uncharged state die an early death.

Good Luck.

Yes, it is ok. It matters that the charging current isn't too high. Anyway we use a special charger for gel batterys.

I use a Battery Tender Jr. that is made for motorcycle batteries. I picked it up at the local auto parts store for $20-30 and they're safe for AGM batteries.

I finally made the choice to invest in a real battery charger at Sears after using the 20-30 dollar trickle chargers and having loads of reliability issues with the actual charging units themselves. I think I paid $90 or $100 and it has been well worth it. Several modes of charging and charges much faster than the trickle units. Also shows battery voltage as it rises etc.

I would save some money and invest in good equipment. Batteries are an essential part of any automotive system. You get what you pay for an personally I have had no luck with cheap equipment in the past.

Hey guys, along the same question. I just got into Sr Rotax and don't have the rotax charger. I have loads of fancy chargers for RC stuff. Now even if the charger is for a different chemistry I assume I can still charge the lead acid as long as I charge to the proper amperage and voltage right?
