Philips Ultra Alkaline AAA LR03 Battery

Philips Ultra Alkaline AAA is a 1.5V alkaline battery in the LR03 size, from the same Ultra Alkaline family as the AA version. It is a single-use pencil battery for the smaller electronics that take the slimmer AAA cell. The cell is a non-rechargeable alkaline in the standard LR03 format, with a leak-resistant construction that counts in devices left untouched for long stretches. Philips positions the Ultra Alkaline range for extended power and shelf life, and states a shelf life of up to 10 years, so a pack kept as a spare is ready whenever a device finally goes quiet. AAA is the size that runs television and air-conditioner remotes, wall clocks, small toys, wireless mice and keyboards, digital thermometers and slim torches. Change every cell in a device at the same time rather than pairing a new one with an old one, and keep spares in their pack somewhere dry — a closed drawer rather than a windowsill — so the cells reach the device in the condition they left the shop.
