A mempac rechargeable battery with polarized pins. Two pin positive and single pin on the negative side. The most common variant is the 3/v150h version. Also note that these cells now replace the obsolete V100R cells.
The cells are of Nickel Metal Hydride construction and are direct replacements for the previous NiCd range that VARTA used to produce. Used in central heating timers eg Worcester Bosch HighFlow 400, Drayton ACL Central Heating Timer LP24.
Please note that a few customers have mistakenly bought 3 of these batteries to make up a 3/V150H/2P battery. If you wish to buy the correct battery, please see the Triple Polarised Pins Version below in Related Products.
