Ridgid Battery Charger Buying Guide
The primary choice is between NiCad and Lithium-ion in these applications. The battery chargers on review will charge both types of battery, but Lithium-ion is more common now, as they have several advantages over NiCad.
There are two types of Ridgid battery charger on review, the single battery charger, and the dual battery charger. The pros and cons of each are discussed in the detailed reviews below.
The single battery types retail in the region of $45 on Amazon, while the dual battery type is in the region of $90.
A battery charger’s power rating affects the speed at which it can recharge a battery. The higher the rating, the quicker the battery becomes fully charged.
It is important to note that fast charging a battery regularly may adversely affect its working life. Its, therefore, advised only to use a fast charger when you need the batter quickly.
The time it takes to charge a battery depends on the power of the battery charger and the amp-hour (Ah) rating of the battery. For example, a 2Ah battery on a 2Ah charger will take an hour to charge. If the charger is rated at 4Ah, the same battery will be charged in 30 minutes.

Battery charging stops once the fully charged state is reached. This prevents over-charging and damage to the battery, plus it saves you on electricity. Once fully charged, the charger switches to maintenance mode to keep the battery topped up at the correct level.

The Ridgid AC840094 Gen5X has the unique feature of accepting two batteries at once. This is very useful, but slightly let down by the fact that it only charges one battery at a time.

Another useful feature is the fast charging rate, allowing two lower amp-hour batteries to be fully charged in less than 60 minutes.
Although this is the most expensive charger on the test, it makes up for this with great additional features. On the front panel of the charger are two pass-through AC outlets, which can be used to power small items below 5 Amps.

Ridgid Battery Charger Problems
Battery charger not working
If nothing happens when you put the battery into your charger, the first thing to check is the outlet’s power. An easy way of doing this is by plugging a lamp into the outlet.
Assuming the lamp works fine, try plugging the charger in without a battery fitted. If the LEDs come on, there may be a fault with that battery, so try another battery if you have it.
In case the battery charger doesn’t light up, it probably needs to be repaired. If you are the original purchaser of the Ridgid tool and registered for the Lifetime Service Agreement (LSA), Ridgid will replace any parts required for free. The LSA is only available on products bought from The Home Depot.
There are two possible fault causes in this case.
- A battery that is too hot or too cold can cause this issue. Try storing the battery in a place that is not too hot or cold for a few hours and then try again.
- The battery may be deeply discharged. In this case, you will need to override the safety circuit to force the battery to charge, until there is another charge for the Ridgid charger to start working.
Battery Charging Tips
- Lithium-ion batteries should only ever be charged in a battery charger designed for them. These batteries contain extra circuits for their protection, and battery chargers designed for NiCad batteries only will not work correctly. All the Ridgid battery chargers on review here can charge either type of battery.
- Although many chargers have a maintenance mode, it is not recommended to leave the battery on the charger indefinitely.
- Protect the battery and the charger from extremes of heat and cold.
- The chargers connect to the mains electricity, so they should be protected from the weather. Water and electrics really don’t mix!
The primary choice between these Ridgid battery chargers is either single or dual battery.
The Ridgid R840095 Gen5X and Ridgid R86092 single battery chargers do what it says on the box, keeping your battery in perfect condition. You have a choice of fast charging or average charging speed. Just remember that continually fast charging your battery may shorten its working life. For home use, either of these chargers will be ideal.
The dual battery charger has plenty of extra features to justify the higher price. Features such as two USB ports and two pass-through electrical sockets could make this the perfect battery charger for you. For tradespeople, out on the road, the extra features may justify the additional cost.
How much is a Ridgid battery charger?
This depends on where you purchase the battery charger. If you buy them directly from Ridgid or their supplier network, they are much more expensive. Genuine Ridgid battery chargers can be purchased on Amazon at a much lower cost. But they will not be in the original box, and the warranty information will be different.
How long does it take to charge a Ridgid battery?
The charging speed depends on the amp-hour (Ah) output of the charger and the amp-hour rating of the battery. For example, a battery charger with an output of 2Ah will charge a 2Ah battery in an hour. A 4Ah charger will charge the same battery in 30 minutes.
How long do Ridgid batteries last?
Several factors affect the working life of your Ridgid battery.
- First, the conditions under which the battery is stored. If the battery is exposed to extremes of temperature, this may adversely affect the battery’s performance.
- Second, how is the battery maintained? Allowing a battery to discharge fully without recharging it for a long-period can adversely affect the cell’s life.
It is recommended to charge your battery fully and, if it is not in use, to recharge the battery regularly.
Is it OK to leave a lithium-ion battery on the charger?
Yes, in theory. However, even though the Ridgid battery chargers have a maintenance mode, it is not ideal for keeping them on the chargers for extended periods.
Does fast charging reduce battery life?
Yes, fast-charging batteries can reduce the life of the cell, although this is still being studied. It is believed that fast charging causes damage to the batteries electrodes, reducing their capacity.
