I have a hummingbird ice 55 and lost the charger. I m an idiot when it comes to amps and voltage. Can I charge these batteries with a trickle charge from a regular car charger. How low does the charger have to go to be safe?

So I answered my own question with some research on line. It all has to do with the amp hours. These chargers are meant for a car battery which are approx. 45 Amp hr. You can do it, but there is a possibility of overcharging. If I have a 1 Amp charger it would charge at a rate of 1 amp/hour. So a 9Ah battery completely dead would take 9 hours if charged with a 1 amp charger. A 3Amp charger would take only 2 hours.
I believe the slower you charge the better it is for the battery. If someone else could chime in that would be great thanks. Found a good explanation for dummies here.

If your location is correct this may fit the bill with a short drive ...whens the last time you charged your battery ? How old is your battery ? ..

I wouldn't recommend using more than 1.5 amps when charging a battery of that size. Rule of thumb is to charge your battery for two hours for every hour you used it.
-
The last time I used the battery was last year. Its probably 4-5 yrs old. The hummin bird says its at 70 %. And I know when I go buy a charger, I'll find the old one....

May have reached the life span of your battery...should be charged after each use ..and once every two months or so between seasons .

Pick up a battery tender jr 12v. Your battery should state on the side what the max discharge/charge rate is, most are 1.5-2A. Car/boat chargers are typically 10-20A and 2A on trickle setting. Trickle setting may work, but I wouldnt chance it.

How could that possibly be a "rule of thumb" when the amount of draw can vary so much?

Kevin23, Pick up a battery tender jr 12v.
After researching this sight, I came across someone recommending the battery tender junior to someone else with my same problem. Might have been you. They look nicer than the other chargers. I ordered one on Amazon last night I'll have it today. Just in time for Sat. Now all I need is Ice. Thanks.
Pretty sure the battery is still good, even though its at 70% I'm still getting a smidge over 12 volts. Thanks for every ones input.

Good video about batteries and charging ..9:59 mark makes a good point

Just an old "rule of thumb" from the days when flashers came with a 7 ah battery and a 500 milliamp charger. Probably doesn'f fit in today's world.

Good video...Thanks.

The real rule of thumb is actually C10, or 1/10 the capacity of a battery. Yours being 9amp should be charged at .9 amp or 900mAmp. Now a 1 amp charger won't do any damage, just don't leave it on for more than 8-9 hours, sort of overnight.
-
I bought the 750mA battery tender junior. It seems nice I like it, it has the technology to not over charge the battery. Took about 3 hrs to charge it to full capacity. All is good now.
-
Yeah the battery tender jr is a nice smart charger.its a maintainer also and wont overcharge a battery.i leave one connected to my snowmobile battery all year.
-
If your goin to charge a smaller amp battery, you don't want to high of an output on you charger. Always safe to go with something like a 2 amp charger or something similar. I was given a battery tender jr. which which only is a .75amp trickle charger so it takes a while but it does the job.
-
The battery will tell you right on it.

As long as you don't charge it with more amps than that you'll be fine.I use a 2 amp ship and shore charger Schumacher 2 amp setting with AGM( if that's your battery type).Usually takes 3-4 hrs depending on battery.A trickle charger could take 12-16 hrs.

I picked up one of these seems to work pretty good.

That's perfect...actually see it's 1.5 amp charge too. The battery tender junior I have is nice but only .75 amp charge so it takes a little longer to charge a 9 amp battery.

Did I read somewhere that slower was better???
