Optimate 2 12V Battery Optimiser / Charger

The OptiMate 2 smart charger-maintainer is the most cost effective solution for long term maintenance of a 12V batteries in any vehicle / craft that is stored in or outdoors.

OptiMate 2 is ideal for standby power applications - the interactive standby mode during long term maintenance reverts to full charge mode if it senses high current drain from the battery.

How it works

 

  1. Battery check: OptiMate 2 must be connected to a battery (retaining a minimum of 2V) to activate its output.

 

  1. Bulk charge stage: Charges at 0.8 Amps constant current to efficiently bring the battery up to 14.3V.

 

  1. Verification stage: Immediately follows bulk charge mode during which the battery's ability to accept a charge and thereafter its charged status is verified. A battery in poor health unable to hold a charge is indicated by the yellow charge LED alternating with the green maintain LED every 3 seconds. For a battery that appears healthy the voltage is limited at 13.6V for 30 minutes while the circuit monitors the actual voltage and the current absorbed by the battery, during which the green maintain LED remains on. If during the 30 minutes the automatic circuit senses the battery requires further charging, the program reverts to bulk charge infrequently until a full charge is achieved.    

 

  1. Maintenance / float charge stage: consists of 30-minute float charge periods followed by 30-minute ‘rest’ periods during which there is no charge current. This alternating “50% duty cycle” prevents loss of electrolyte in sealed batteries and minimizes gradual loss of water from the electrolyte in batteries with filler caps, and thereby contributes significantly to optimising the service life of irregularly or seasonally used batteries. During the 30-minute charge period the circuit offers current to the battery within a safe 13.6V voltage limit (“float charge”) allowing it to draw whatever small current is necessary to sustain it at (or close to) full charge and compensate for any small electrical loads imposed by connected circuitry, or the natural gradual self-discharge of the battery itself.   During the 30-minute rest period the battery voltage is monitored. For a good battery the green maintain LED should remain on. The program will return to bulk charge if the battery voltage cannot remain above the test level during the rest period.

 

  1. Interactive standby: A load that causes the battery voltage to suddenly reduce will return the program to Bulk charge mode. After the battery has been recharged the program returns to the maintenance charge & rest cycle. OptiMate 2 can remain connected to the battery indefinitely - the battery will remain cool and safe. And optimally charged. Of course.

An Actual Nice Chair for a Decent Price. +2 for the Tool.
Color: Black Grey
Welp, My old chair finally broke, so It was time for a new one. I ended up coming across this chair here, and I couldn't really find anyone talking about it online. I decided to give it a shot since it was on a good sale for Christmas, going down to 99$. I'm going to be honest, I am pleasantly surprised. The cushioning for it is a little firm, but that is perfect for me. Its pretty average when it comes to office chairs, but having the added lower back support is a great touch. I have no complaints about it. The one thing that I am actually really happy about isn't on the chair. Don't get me wrong, over the week I have been using it, It has been nothing but great. That thing is the actual tool it came with. Its a basic Allen key, but the top of it is a molded handle instead of a "L" piece of metal. It made the already easy process of putting together this chair even better. Even after this chair has ran its course like all other chairs, I'm going to still use this tool. So yeah, I think 5 - stars pretty accurately describes how I feel about my chair.

Comfortable chair that works great for long hours
Color: Black
I’ve been using this office chair for a few days and it’s been very comfortable for working and longer desk sessions. The high back design and ergonomic support help maintain good posture, while the cushioning stays comfortable throughout the day. The chair feels sturdy and stable, and the 330 lb capacity gives it a solid, durable feel. It also rolls smoothly and quietly, which is nice when moving around the workspace without creating a lot of noise. Overall, it was easy to assemble, looks professional, and offers great value for the money.

Very Comfortable Ergonomic Chair - Great for Long Work Days!
Color: Black, Color: Black
I’ve been using this ergonomic office chair for a couple of weeks now and I’m genuinely impressed. For the price, it offers excellent comfort and support. What I like: • Very comfortable padded seat and backrest — I can sit for 8+ hours without back pain. • Good lumbar support and adjustable height/armrests. • Holds up to 330 lbs easily (I’m 240 lbs and it feels very stable). • Smooth rolling wheels and sturdy base. • Easy to assemble (took about 20 minutes). The mesh back breathes well and doesn’t get hot. It looks professional in my home office too. Overall, this is a solid ergonomic chair. If you spend a lot of time at a desk, I highly recommend it. Would I buy it again? Yes, definitely.

Great if you're average height.
Color: Black
Comfortable for the price. The seat could be a bit better, but for a budget friendly ergonomic chair, it's well made and has helped a lot with my back pain caused by my previous desk chair. Assembly wasn't terribly difficult, though I did have one screw with damaged threads. Luckily they ship spare screws in the kit, so that was a non-issue. Rollers work great on my small rug and hard flooring and don't tend to tangle cords or cables too much. Size wise, works great for my frame (5 ft 6 in) but for someone more than a few inches taller than myself, you should probably look at another chair.

Great chair
Color: Black
I am very happy with my purchase. Easy to assemble but be aware your drill bits included with your set won't fit their screws. However, you can get a fair bit done with the drill and then use tool included to adjust. Super comfortable and exactly the right height for my desk. Highly recommend for quality exceeding price point.
