So, as a recap, a trolling motor battery is a chargeable 12V battery that’s used to energy the motor when it’s hooked up to the kayak within the water. Like most batteries of this kind as utilized in caravans, boats and tenting setups and so on., they should be recharged throughout, or after use. That is the place a battery charger comes into play.

Put merely, it’s the system that fees the battery.

Varieties of Chargers

Okay, with regards to 12 V battery chargers for trolling motors, there are a variety of choices to select from. These embrace:

Plain electrical chargers – My dad and mom used to have one in all these to cost their 12V golf cart batteries. They hooked up the charger after which set an alarm to show it off after a sure period of time. That’s as a result of these ‘old style’ chargers merely do one factor – cost the battery at no matter wattage (see under) has been set with none variation or battery administration. They are going to cost the battery till you flip it off.

Sure, these work and to be sincere, some cost approach quicker than the opposite fashions listed under nonetheless they may considerably cut back your battery life – and as my dad discovered, may cause even the ‘leak free’ batteries to interrupt their seals if over heated by cost as effectively. My recommendation – depart these ones on the shelf.

Sensible chargers – These are the brand new breed of chargers that handle the speed of cost to a battery primarily based on its voltage ranges. These chargers truly ‘learn’ the battery to find out its present voltage degree and distribute cost accordingly. Generally, most will cost totally till the battery reaches round 80% then regulate currents to high up the battery with out overcharging or heating it to unsafe ranges (as occurred to my dad’s battery above).

These battery administration protocols will be certain that every battery is charged to optimum ranges pro-longing use instances and battery life on the identical time. Ought to a charger be left on for a better time period, then the sensible charger will regulate to upkeep mode the place it robotically switches the cost on and off dependent upon battery wants.

Extra superior fashions listed below are known as precision chargers with better skills round upkeep mode and voltage adjustment at varied phases of the charging cycle.

Trickle chargers – Many (together with myself at instances) get trickle and sensible chargers confused – or take into account them the identical factor. Sensible chargers can adapt to upkeep mode as outlined above whereas a trickle charger will ship a cost that is the same as the batteries charge of self-discharge to maintain the battery totally charged, or will cost depleted batteries at a really sluggish charge as a restoration course of. As soon as this has been achieved, the trickle charger ought to be disconnected.

These are used for when a battery is just not going to be in motion for some time and not likely appropriate for these wanting to make use of and recharge a battery at common intervals. Don’t get me fallacious, these will work however as per the plain charger above, can overcharge if not monitored.

Energy pack chargers – these go by plenty of completely different names however consider them as the identical factor as the ability pack that individuals use to cost their cellular/cell telephones when not hooked up to an influence provide. Primarily used as everlasting moveable chargers within the boat or kayak, these are charged by merely plugging into an influence provide till they’re ‘topped up’.

Then, dependent upon the mannequin (and the way a lot you pay), they may keep cost to the battery/s while out on the water as a trickle, sensible or common charging capability.

Photo voltaic chargers – The principle distinction with photo voltaic chargers is that they draw their energy sources from the solar slightly than {an electrical} supply. As soon as that’s performed, the charger element works in the identical capability as above – i.e. trickle, sensible or energy pack and so on. primarily based on the mannequin that has been bought.

The knowledge above has hopefully given you a great define with reference to trolling motor battery chargers nonetheless when selecting one in all these, there are another issues to think about. A few of these will decide the charger kind that you just select and others could also be private desire.

With this in thoughts, listed below are some issues to look out for:

Battery sorts

Typically, with regards to batteries for a trolling motor, most chargers will do the trick. Nonetheless, if you’re unsure what you will have, here’s a fast rationalization of the 2 main battery sorts that you will have to your trolling motor:

Absorbed Glass Matt (AGM) – AGM batteries (also called Sealed Lead Acid or SLA), are lead acid batteries which are sealed, leak-proof and upkeep free. They’re typically fast charging, last more on a cost and have an extended life-span.

These batteries are typically deep cycle – that means that they’re designed to discharge small quantities of present over an extended time period. Nearly all chargers will work on AGM batteries – given they’re successfully the usual lately – however at all times value a verify anyway.

Lithium-ion batteries: These are a more recent know-how in the marketplace and work in the identical vogue as your cellular/mobile phone battery. They’re costlier than the others however are additionally typically smaller and lighter. They are going to deal with being charged and discharged quite a bit higher and have a for much longer cycle life (variety of instances charged and recharged) as effectively.

Not all chargers are appropriate for these kinds of batteries so do your homework earlier than buy.

Sort of trolling motor

This shouldn’t be a giant situation nonetheless earlier than you head off to your favorite battery retailer (or click on on my hyperlinks under), simply verify the suggestions in relation to your motor. Some producers will void warranties if the wrong battery kind or AH specs are used and plenty of require a couple of battery to run that means your charger might have to have the ability to deal with banking as effectively.

Battery banks

Aa above, some trolling motors require two, and even three batteries to run – sometimes called battery banks. When you find yourself taking a look at chargers, many will stipulate what number of batteries they will handle directly. So if in case you have a couple of battery, be certain that your charger is rated for the related battery financial institution quantity.

Amp hours (AH)/Watts

Trending: The Best Trolling Motor Batteries of 2022

12V batteries are stamped with an ‘Amp Hour’ ranking which is a unit of electrical cost decided by the variety of amps being pulled from the battery divided by the overall Ah ranking of the battery. For instance, a battery that’s rated at 100AH will give 100 amp hours of energy when totally charged. So if a trolling motor is working at a medium pace and pulling 10 amps of energy from the battery, then working continually at that pace will imply that the battery will final roughly 10 hours till it ‘runs out’. i.e. 100hours/10amp = 10 hours.

In the case of charging a battery, charger capabilities are recorded in watts or amps. Typically, the upper the wattage, the quicker your battery ought to cost nonetheless if the wattage is simply too giant for the battery, it will probably injury it.

There are such a lot of variations to calculation on the market (albeit primarily based on the identical science) that my eyes went crossed in about 5 minutes, however I’ve discovered a formulation that I believe can provide the fundamentals in therms of amp altering necessities:


  1. Decide the battery voltage – typically 12 volt
  2. Decide what number of batteries are to be charged (1,2,3 or 4) = i.e. your battery financial institution
  3. Find the Amp hour ranking for the battery’s capacities (AH) and if a couple of battery, add them collectively if relevant
  4. Decide your most well-liked re-charge time necessities (6 hours minimal, often 24 hours most – if not recognized, assume 10 hours)
  5. Divide complete Ah by the re-charge time to get charging present – e.g. 100Ah / 10 hours = 10 Amps.
  6. Add 20% to permit for battery in-efficiency – e.g. 10 AMPS + 20% = 12 AMPS
  7. Decide any further load present on the battery throughout re-charging – e.g. 24 Watts / 12 Volts = 2 Amps = 12 AMPS + 2 AMPS = 14 AMPS.
  8. Select the subsequent finest charger within the vary – e.g. 10 – 15 amp sensible charger


Watts are Voltage multiplied by present, so taking the above instance with the 12 volt battery:

  • 1 Amp x 12 Volts = 12 Watts for 100 hours
  • 2 Amps x 12 Volts = 24 Watts for 50 hours
  • 10 Amps x 12 Volts = 120 Watts for 10 hours
