Replace with new battery pack!

For you do-it-yourselfers, Mark VII batteries need to be replaced after a few years. Besides going dead and not holding a charge, these batteries can start to leak acid and destroy the components in the meter.

Here is a direct replacement battery pack that is identical to the one being used in the meter and reasonably priced.

It’s easy to remove the back of the meter (3 screws) and remove the battery (two screws). You just use the existing battery connector on your old battery. The connector has a self-splicing connection.

We've been getting new battery packs from Batteries Plus. They take the connector and attach it to the new pack with the batteries and only charge us $13.
Been doing this with all our meters and they work fine.

Be careful to get the wires backwards! A I recall black goes to black and red to red, but just take a look before you remove the old wires and put it back the same way. Survival of your meter is not guaranteed if you get it wired backwards.
It is tricky to get the new wires jammed into the connector properly, I usually use a small flat blade screwdriver. Align the new wire in the slot, place the connector flat on a hard surface, put the blade of the driver parallel to the wire and give it a solid shove to force the wire all the way down into the slot. You don't strip or tin the wire first, the connector is able to bite through the insulation and make a good connection. At HEM they do it with a special tool, but you can do it at home if you just make sure to force it down all the way. If you use a driver that is too big you can bend the connector clips. If you make a mess of the connector, just strip the wire and solder it on, but be sure the solder does not flow down too far inside the connector. If it does you won't be able to connect it!
It is hard to shove the connector in the wrong way, but if you do the meter won't work. Just don't force it if it seems not to fit well.

Taking a crisp photo of the connector and wire arrangement before disconnecting might make life far easier when it comes time to connect the new battery pack.

An identical (actually higher rated and higher quality) battery pack is available in the uk (built and wrapped ready with cables if you ask them to build it for you)for £14 including free p&p in the uk!
Contact strikalite.co.uk
01543 683122, Roger.
Ask for 7 of Product ID: 629
Finally, I found out the meter may not charge simply because the fuse on the meter's charging board is blown. Check it.
