Generator battery chargers ensure reliable power

Generator battery chargers are one of the most critical generator components. The battery charger is a inexpensive and often-ignored widget that keeps tens of thousands of pounds worth of generating capacity works as specified. After all, your generator is useless if it doesn’t start. Battery chargers are the tiny cogs that keeps your business operating.

Generator battery chargers from ComAp and Datakom

IPU battery chargers suit a variety of environments. Our expert assistance makes sure you get the perfect fit

Generator battery chargers are permanently connected to your generator’s battery and trickle charge it to ensure the generator starts when required.

IPU supplies three ranges of battery chargers to suit different environments and we can help you select the correct one. You can either:

  • use our product selector
  • use the questions on this page to guide your choice; or
  • phone our expert team who will talk you through the selection process


Which battery charger is right for your generator?

The following questions should help you decide which charger you need:

  1. Do you need 12V or 24V output or both? Your battery determines this. If you’re buying for mobile field engineers you may need chargers that would suit both battery types.
  2. How will you mount the battery charger? You may want to mount it on a DIN-rail, bolt it to a panel or leave it loose.
  3. How fast do you need your batteries charged? Generator batteries can be charged slowly in most cases. This is safer for the battery and lets you buy a less expensive charger with a lower output current (measured in Amps). Higher output devices charge the battery faster.
  4. Do you need to charge ‘exotic’ battery types? If you always use standard lead-acid batteries you have a wide choice of chargers from ComAp and Datakom. If you want to charge VRLA, AGM, gel or NiCad batteries you need a charger from the ComAp range.
  5. How expert are your fitters? If there’s a chance they’ll connect the charger the wrong way round (you may laugh but it happens) you need a ComAp battery charger with reverse connection protection.
  6. Will you disconnect the charger before you start the generator? The answer is invariably “no” but we ask anyway! If the charger stays connected during start-up you need short-circuit protection.
  7. How often are your batteries and battery chargers checked? When they’re in a remote location and rarely inspected you need a charger with a fail alarm. This feeds an alert to your generator’s controller which relays it to your management systems.


The difference between generator battery chargers

We all have budgets and a battery charger might not seem like a top priority. Skimping on a battery charger and getting a cheaper model is problem solved, right?

The principle is sound but you still need to make sure you buy the right sort of charger, and in general, the higher the charging capacity (the current, Amps), the higher the cost. The fast chargers are the more expensive chargers.

The other factor that affects price is intelligence. Smarter chargers stress the battery less, therefore extending its life. Even the smarter battery chargers is the fraction of the cost of a new battery.

If you have a battery in an inaccessible location, low maintenance is especially important. You might want ComAp’s InteliCharger 500 for this site because its microprocessor control stresses the battery less than other chargers.

The overload protection on all the battery chargers ensures they cut out when the battery is fully charged which reduces stress on the battery.

IPU’s service

IPU offers far more than simply sending you a box containing a new charger:

  1. We will make sure you get the right charger for you – we won’t just sell you what we have and hope it works.
  2. We know the environments that chargers are placed in. IPU’s Engine Control division has decades of experience working with all aspects of gensets and power-generation equipment so we can answer the follow-on questions that would baffle box-shifters.
  3. Replacing defective and cheap chargers will amount to more than the money you originally saved.
