Product features

Clearance stock at a clearance price, while stock lasts.

The Thunder TDR02104 is a 4A, 8 stage automatic pulse charger for small 12V batteries from 6 to 70Ah (50 to 200CCA), with settings for Gel, lead acid, AGM and calcium types.

The ride on mower or jet ski that sits all winter usually needs a jump start come spring. A small 4A charger looks after batteries of that size, and the pulse mode works against oxidation and stratification so the battery lasts longer.

Protection

  • Overcharge protection
  • Reverse polarity protection with flashing LED
  • Short circuit protection
  • Over temperature protection

Charging voltages

  • Gel: charge 14.3V, boost 14.8V, float 13.3V

Using it

Pick the battery type before charging. Thunder lists it as water resistant, but keep it out of the rain. It will start charging from 0V, so it can attempt a very flat battery.

Frequently asked questions

Will it charge my car battery?

Thunder rates it for 6 to 70Ah batteries (50 to 200CCA). Check the Ah rating on your car battery; if it is 70Ah or less, it is in range.

Can it charge lithium?

Thunder lists Gel, lead acid, AGM and calcium only.

Which setting do I pick?

Match it to the battery: Gel, lead acid and AGM, or calcium. Each runs its own charge, boost and float voltages, so set the type before you start.
