Marine Batteries - Making an informed choice…

Marine Batteries - Making an informed choice…

All boats have a need for electricity onboard and a good working battery is of great importance, not only for running your equipment, but also from a safety perspective.

It is a simple fact that all batteries degrade over time They are a finite commodity, therefore all batteries will need replacing at some point. When that time comes, it is important you choose the right battery for your requirement. However, how do you know which the right battery is, as every boat will have a different requirement depending on many different factors.

It can be very difficult to decide as the choices are plentiful. Technology, Reserve Power, Cranking Output, Voltage, Weight, Size, etc. The first consideration should always be based on what the battery is expected to power. Will the battery be required solely for starting the engine, will it need to run key instruments, or is there a host power hungry of equipment in the cabin that needs to be powered such as a fridge, microwave, etc.? Maybe all three?

Marine Batteries basically fall into three categories from a performance-based perspective:

  • Cranking Battery
  • Deep Cycle Battery
  • Dual Purpose Battery

Other important considerations when purchasing a new battery should be:

  • Battery Capacity – Reserve Power (Ah rating)
  • Battery Dimensions, i.e. the battery’s physical size (make sure the battery fits where it is supposed to)
  • Weight (does the battery need to be handled / moved regularly)
  • Output (marine cranking amp rating, reserve capacity rating, cold cranking amp rating)
  • Technology (flooded lead acid, gel, AGM, lithium-iron)
  • Warranty

*Always check your owner’s manual for the recommended battery types and ratings. Always choose along with the rating equal to or greater than the recommended value.


Cranking or Starting Batteries

These types of batteries offer high bursts of power for short periods of time to start your engine. Starting batteries are designed to put out a large amount of current for a short period of time. A cranking battery usually has a higher number of lead plates that are thinner and sometimes purer lead, with more surface area to provide the off the mark power.


Deep Cycle Marine Batteries

If you are looking to power both onboard electronics and accessories a deep cycle battery would be what you need. A deep cycle battery puts out less energy density for a longer period of time. It is designed to produce discharge cycles while the engine is off and therefore not being charged. A deep cycle battery generally consists of fewer lead plates that are thicker and more robust to provide continuous power output over long periods of time.


Dual Purpose Marine Batteries Batteries

Dual purpose batteries are designed to both start the engine and to power any equipment / electronics.

When purchasing a new battery, don’t forget to recycle your old one. Lead acid and Lithium Iron batteries can be safely completely recycled when done properly in the right facilities.

A Battery Monitor is highly recommended

Marine batteries have a pretty tough time of it including conditions out at sea, seasonal / occasional use and long hours without being recharged. BBL Batteries always recommends it is worth investing in a battery monitor. A huge number of marine batteries are either massively under-charged or massively over-charged which will certainly end their life prematurely. If you opted for a LIFOS, Lithium Iron battery then you would have the benefit of a built-in communication system that talked to your smart device (smart phone, tablet etc.) via a bluetooth app which would constantly provide you with the key performance indicators of the battery such as state of charge, power output / input etc.

Exceptional customer service from a very knowledgeable staff member. We were directed to the trading estate to find a Europarts by Green Flag as our previous battery had given up the ghost whilst on holiday. In searching for their unit we came across BBL and instantly ‘felt’ and that we would be looked after better. Not only was the customer service first class but the battery was significantly less than a lesser quality battery at Europarts. We will definately advise friends and family that holiday in the South West to use your company for their battery needs. Thank you..

As a keyworker my car was important at this time. Unfortunately my battery died on me. Rang up BBL batteries Monday morning, paid over the phone, instructions given as to where it would be left for social distancing purposes. Partner collected the battery half hour later.  Brilliant service. Would use again

Very good service from start to finish.  Staff pleasant and helpful.

I was surprised to find that the battery I purchased was manufactured by

Yuasa,

As an aside, I was employed by Lucas batteries and took an early retirement

in late 1996 just as Lucas and Yuasa joined forces.

Amazing help and service from the Swindon Branch this morning after my car wouldn’t start and taking a recommendation to bring it to BBL. Matt and the team were really friendly, helpful and efficient from my initial phone call to fitting, which was done immediately!  I am very thankful and will certainly be recommending this place to everyone. Thanks again highly recommended!
