How To Choose The Best Heavy-Duty Battery Charger?
Step 1: Choose the correct charging amperage
You’ll want to look for a few features when purchasing a commercial battery charger. The most important is the amperage, which should be around 10% of the ah capacity of your battery.
Step 2: Understand your own needs
It’s essential to consider what type of batteries you have: SLA, AGM, or Lithium.
You’ll also want to look at special functions that you may need from your battery charger. For example:
- Do you need a charger with Boost start function for boost starting if batteries are deeply discharged?
- Or do you want a dump charger to charge a dead battery easily?
Then make sure to look for those specific functions when shopping. Otherwise, you may end up with a charger that doesn’t meet all your needs.
Step 3: Choose the right type of battery charger
There are 3 types of heavy-duty battery chargers:
