Frequently Asked Questions
Can I leave my deep cycle marine battery charger connected?
If you are not using the battery, then there is no reason to keep it connected all the time. Keeping it connected may end up in some kind of malfunction and to something worse.
Can I keep my marine batteries in trickle charge mode?
Yes, you can. Because deep cycle marine batteries don’t tend to heat up in trickle mode, hence no long-term damage if kept in trickle mode.
How often should I charge my deep cycle marine batteries?
If you have a lead-acid battery or an AGM one, it is suggested to check on them every 30 days or so. A better option is to invest in a battery maintainer that comes with deep cycle marine battery chargers.
Do marine batteries require special chargers?
No. They use the same charger as other batteries. But the charger depends on the kind of battery you have. If the charger does not support the kind of battery you have, it won’t charge or even damages the battery.
Any battery is good as it is taken care of. With that said, you have to buy the right kind of charger for your battery. If the charger doesn’t match in terms of battery compatibility, it might damage the battery. Also, the amperage and volts of charging is a crucial element. If the amperage is higher than the battery charging capacity, it might fry the battery or damage it permanently. So always go for the charger that you need and read the specification of your battery and the charger to match. This way you will prolong your battery’s life and the charger.
