Your TV remote just died again. So did the wireless mouse. And somewhere in a drawer, three dead AAA cells are waiting for a trip to the recycling bin that will probably never happen. Portronics thinks it has a fix for that entire cycle, and it just got an upgrade.
The company has rolled out the Lithius Pro series in India, a second-generation version of its Type-C rechargeable battery lineup that first showed up as the Lithius Cell. The Pro models keep the core idea intact: a standard AA or AAA battery with a USB Type-C port built directly into the top, so there is no separate charging dock to misplace. What has changed is the number that matters most, the capacity, which jumps meaningfully over the original Lithius Cell in both sizes.

What Exactly Is a Type-C Rechargeable Battery
For anyone new to this category, a Type-C rechargeable cell is a lithium-ion battery shaped like a regular AA or AAA, with a tiny USB-C port hidden under a flip cap or rubber seal near the positive terminal. Instead of pulling the battery out and slotting it into a separate charger, you plug in the same cable you already use for your phone or earbuds.
An LED near the port blinks while charging and turns solid once the cell is full. It sounds like a small change, but it removes the biggest friction point of rechargeable batteries, which is needing a bulky charging cradle sitting around the house.
Lithius Pro AA and AAA: What’s New
The Lithius Pro AA is rated at 2066mAh with a 3100mWh energy rating, a sizeable step up from the 1480mAh figure on the original white Lithius Cell AA. The Lithius Pro AAA comes in at 542mAh with an 814mWh rating, again ahead of the outgoing 440mAh AAA variant. Both retain the 1.5V output that most household electronics expect, so there is no compatibility guesswork when swapping out old alkaline cells.
Portronics has also switched up the look. Where the original Lithius Cell shipped in white, the Pro version comes in a matte black finish with the model name printed along the body. Charging input stays at DC 5V through the Type-C port, and Portronics has retained over-current and over-discharge protection along with a low self-discharge design, meaning a charged cell should still hold most of its power even after sitting unused for weeks.

Who Actually Needs These
The capacity bump matters more for some devices than others. A wireless mouse or a TV remote does not pull much current, so even the older Lithius Cell handled those fine. Where the Pro variants earn their keep is in higher-drain gear: gaming controllers, wireless keyboards, flash-heavy point-and-shoot cameras, and kids’ toys that chew through batteries in a single afternoon. For those, the extra headroom on the AA cell in particular translates to noticeably longer runtime between charges.
There is also a straightforward money argument here. A household running through two AAA cells a month for a remote easily spends more on disposables over two years than the one-time cost of a Lithius Pro twin-pack. Add in the environmental angle, since fewer alkaline cells end up in landfills, and the case gets stronger still.
Price and Availability
The Lithius Pro AA twin-pack carries an MRP of ₹799 and is currently listed at a discounted price on the company’s own site as well as major online marketplaces. The Lithius Pro AAA twin-pack has an MRP of ₹899, also available at a reduced launch price.

Both Pro variants come with a six-month warranty from Portronics and ship with a dual Type-C charging cable in the box, so there is no need to hunt for a compatible cord separately.
Charging and Safety in Daily Use
Charging behaviour mirrors what existing Lithius Cell owners are already used to. Plug in a Type-C cable, and the LED blinks blue to show charging is underway. Once it turns solid, the cell is topped up and ready to go back into whatever device pulled it out in the first place. Portronics quotes up to 1000 charge cycles for the Pro range, which at even moderate usage should outlast several years of disposable battery purchases.
The built-in protection circuit is worth calling out for anyone who has been burnt, sometimes literally, by cheap third-party rechargeable cells in the past. Over-current and over-discharge protection help prevent the kind of swelling or leakage that gives lithium-based AA and AAA batteries a bad name in some circles. Combined with the reinforced steel shell mentioned on the packaging, these are built to handle the physical bumps that loose batteries take inside remote controls and toy compartments.
How the Pro Range Fits Into the Market
Rechargeable AA and AAA batteries are not new, but most of the older nickel-metal hydride options still need a plug-in charging dock. Type-C rechargeable batteries as a category have picked up pace over the last year or two in India, with brands like Ambrane also offering similar Type-C AA and AAA cells.
What sets the Lithius Pro apart within Portronics’ own lineup is simply more runtime per charge, aimed at users who found the original Lithius Cell a little light on capacity for demanding gadgets.
For anyone still deciding between the two generations, the maths is fairly simple. If the primary use case is low-drain gear like remotes and wall clocks, the older Lithius Cell AA and AAA remain solid, cheaper options. For gaming controllers, high-usage toys, or cameras, the extra capacity on the Lithius Pro makes the price difference worth paying.
